Windows 7 USB/DVD Download Tool (WUDT) is unable to copy files
This post explains why the Windows 7 USB/DVD Download Tool (WUDT) is unable to copy the install files to the USB drive in some cases. The tool allows you to create a copy of your Windows 7 ISO file on a USB flash drive.
By Michael Pietroforte - g+ - Thu, April 8, 2010 - 269 comments Michael Pietroforte is a Microsoft Most Valuable Professional (MVP) with more than 28 years of experience in system administration.
You might have heard of the stir that Microsoft’s Windows 7 USB/DVD Download Tool (WUDT) caused last year when some Open Source watchmen recognized that the tool contained code that violated the GPL. Microsoft was then “forced” to release WUDT under GPLv2. Considering the upset in the media about this incident, I expected a luxurious tool that comes with lots of customization features. I was somewhat disappointed to discover it does nothing else but copy the contents of a Windows 7 install DVD to a USB stick and make it bootable.
The funny thing is that WUDT even failed to perform this simple task with my no-name USB stick. This message was the only thing that the Open Source tool could do for me:
We were unable to copy your files. Please check your USB device and the selected ISO file and try again.
At least, my cheap stick wasn’t the cause because everything worked perfectly when I manually did the job (hopefully without violating any Open Source laws). So, I thought, I would write this post for those who might run into the same problems and think they need to buy another USB stick. After all, this is Microsoft software and there are not many options to integrate bugs in such a simple tool.
Anyway, here is what you have to do. Launch a command prompt with admin rights and run the diskpart tool. Note: Before you run these commands read the warning below!
diskpart
list disk
select disk #
clean
create partition primary
select partition 1
active
format quick fs=fat32
assign
exit
The “list disk” command will show you the connected drives and with “select disk”, you can choose your USB stick.
WARNING: Be careful to select the right drive or else your day won’t have a happy end because if you select the wrong drive you will lose all your data on this drive!
The crucial step here is the “clean” command. It overwrites the MBR and the partition table (thereby, deleting everything on the stick). My guess is that WUDT misses this step and only formats the flash drive. It appears my memory stick had some odd partitions (which is not uncommon). When I tried WUDT again with this prepared stick, the Open Source tool mastered its task without further murmur.
By the way, this is also the reason why you shouldn’t use the Windows Disk Management applet to prepare the USB stick. This GUI doesn’t offer a clean command.
After you prepare the stick, you have to copy the contents of your Windows 7 DVD to the thumb drive, and you are done. If you only have an ISO file, you can use Virtual CloneDrive to mount the Windows 7 install DVD first.
Instead of formatting the partition with FAT32, you can also use NTFS (like WUDT does), but then you need an extra step to make the drive bootable:
Bootsect.exe /nt60 X:
“X:” is the drive letter of your USB stick. Bootsect.exe can be found on the Windows 7 DVD in the boot folder. However, I can’t really recommend using NTFS. My USB stick, at least, appeared to be slower with NTFS.
Thanks for posting this Michael.
I used the WUDT countless times on the same Kingston G2 stick, until one time it decided not to restore – strange.
Anyway, it’s working again so thanks again!
That’s interesting. I thought it is only a problem with unprepared USB drives. Seems there are some other bus in WUDT.
This worked to correct the problem for me. I had previously used my USB drive to boot an Apple Mac X OS and clearly it had some residual MBRs that needed to be cleaned.
Thanks Michael!
That clean command did the trick. U just saved me a whole day of fiddeling arround!
I’ve been struggling with this for a while. This post cleared it right up. Many thanks!
Fantastic workaround – a big thank you.
thanks, it works!
Nice one! Thanks very much, bit of a head scratcher!
I recently had the same problem with this MS tool, The solution was quite simple: disable Avira (free antivirus tool)! It turns out that the antivirus software detects malicious activities on the usb device (surprise, we are trying to make it bootable & copy stuff like autorun.inf!).
So if you see this “can’t copy files”, try to disable your antivirus software!
thanks very much — i was totally stuck and this worked great.
The problem resides in the partition table format.
WUDT need a ms-dos partition table format, some cheap usb sticks don’t have a partition table, o some special operations like dd an debian image to the sticks erases that partitions.
My solution is open gparted (or any partition editor) and create a ms-dos partition table on the stick.
After that WUDT will work perfect.
Thanks
diskpart command with clean did the job
thanks, it really works!
Great post, thank you very much!
Worked fine!
big thanks, it’s helpfull
Thanks Michael, your post solved the problem for me.
Diskpart doesn’t work well in xp.
Because usb drives don’t seem when typing “list disk” at XP.
They will be able to seem at least Vista.
Thank you for sharing. Microsoft tool is annoying….your steps did the clean install from usb stick quick and easy.
Thanks again for helping me getting out from nowhere
Thanks a lot! this is was so helpful!!
I’m not the most computer literate. Is there an idiot’s guide for the command prompt? Or at least for this process?
Nevermind. Trial and error prevails! (And I didn’t blow up my computer!)
Much appreciated, have been experiencing this kind of strange behaviour. Anyways it works flawlessly for me now, thanks a lot for your advice
greeat!
nice ware…
but something wrong with my usb device after using this software.
my computer did not recognize my usb device anymore.
can anyone help me?
Good Work guy !!!
work pefectly !
Thanks a lot for this post, worked a treat when my Sandisk Micro Cruzer wouldn’t work with the USB DVD tool, where it had done before.
I have another USB stick with the same problem so gonna test your solution with that and if it works, you just resurrected an old USB stick for me!
Cheers!
Thanks a lot. This worked for me.. I no longer get that ugly error!
Thanks Brother. Great.
Just like Rene Treffer above. I also got the message do to Avira. Disabling Avira allowed me to use WUDT.
good job~ thank you~
For your information:
You can also correct that problem with the “HP USB Disk Storage Format Tool 2.2.3″, download here or google it:
http://www.softpedia.com/get/System/Hard-Disk-Utils/HP-USB-Disk-Storage-Format-Tool.shtml
Run it as admin, choose the correct drive and do a quick format.
Thank you, my problem has been resolved, thanks a lot.
Thank you, great!
Thanks a lot man, works great!
wow thanks man helped me a lot.
Hey guys, just format your usb drive with HP USB DISK STORAGE FORMAT TOOL, which can also be found here:
http://files.extremeoverclocking.com/file.php?f=197
and format your usb stick by selecting fat32 filesystem (quick format will do, no need to check msdos filesystem stuffs)
and again run the WUDT, and this time it copies. thanks all.
Thanks very much, this worked for me!
Yes, the clean command did the trick. Thanks a lot.
great! it’s working perfect
Hi man
I consider myself to be an IT prof or atleast somewhat pro
– I had a hard time getting this to work but with your guide it just worded Flawlessly. Thanks mate
oh thanks so much for this post. you are the best ever.
u r great person ever that problem scared me alot i thught my USB Stick is gone thanx alot brother
you saved my life twice with this Tut
thank you so much Michael Pietroforte
This worked perfectly for me. Thanks!
There are a lot of guides on the net regarding making a thumb drive bootable with or without the download tool, but none explains WHY it works (and doesn’t work) like yours do. Two thumbs up!
I have similar problem, but the solution was to disable antivirus which blocked copy process.
DUDE…………. YOU ROCK!!!!!
OMG, I love you!!! Thank you!!!
thanks alot…haha, it is copying…
You can try HP USB Disk storage format tool.
I formatted my USB with this tool and then used windows 7 USB DVD download tool and it worked like a charm.
I had error like can not copy before.
ok you now saved my life 3times
thank you again
Thanks a lot!!
However you don’t need to manually move the files to the USB. I did the command promt thing then ran Windows 7 USB DVD Download Tool again and it is now copying the files onto the USB.
Thanks a lot though!!
)
Thx alot. The step indicated resolved my issue.
Thanks very much!!!
I was about to throw away my usb stick.
Thank you!! it works awesome
Great! Thank you. Very helpful information.
Thank you very much. It works very good
This worked brilliantly, thank you!
THANK’s a million now it is perfectly working I tried everything from quick formating to disk formating but nothing worked except yours THANKS !
I am not sure when it comes to choosing the ISO file, I have no idea what to click! any suggestions?
thx dude my problem was solved as you describe, very good Tutorial!
Thank you so much!!!!!!111111
thx a lot!!!
i really thought mb its my stick, couse it worked with my old one i just lost.
but now after the preparation no problem ;D
Really great job with that article.
Thanks a lot.
Thanks, it worked.
Thank you so frekkin much!
I had this problem.. I solved this problem desactivating my avira…
Thanks to Michael Pietroforte for the procedure and Rene Treffer for the tip related to Avira. It works fine to me now!
Thanks a bunch for posting this. I knew my USB stick was not defective but the download tool would not copy the files no matter what I tried. Using your instructions, I was able toa get it working.
Thanks bro that helped a ton
This post was really helpful!! thanks for your help!!!
thank’s. i’m so happy about this solution
Whoever you are buddy. I salute you for posting the MOST SMART WAY to get rid of this annoying error.
This works!
I made a Google Chromium OS boot disk on my USB drive and it created half a dozen non windows partitions. Disk manager was having problems even deleting them, I got another program to remove them and used Windows to reformat it but it was the MBR that was causing problems.
Thank you!
Had the exact same problem, found this through Google.
Quite lame that Windows’ disk management doesn’t offer the “clean” option in the GUI and that the WUDT doesn’t realize where the error lies.
I’m trying this. But the clean option wont work… Everytime I select my flash drive and try and clean it. It says there is no disk selected. Please select a disk and try again.
NEVERMIND.. Presistence is key.. I went over to a computer with windows 7 and did it from there.. God dam windows xp 32bit.. God dam you to hell..
dude – u rock – I installed a WIN XP on my second partition, and it destroyed the MBR of WIN 7, thanks to you its now copying files to my USB – I hope I can boot from my USB to fix the MBR…
thanks a lot
Thanks once more! Worked flawlessly.
Thanks! Had the same problem and your solution worked like a charm!
Wow. Seems that I’m the only idiot who can’t get it to work. I tried with diskpart, which seems to do what it is supposed to do, but to no effect. Tried the HP Tool, but that won’t work either. Turned off the antivirus software (ESET), but there’s nothing to be done. It just won’t give in.
My USB Stick is from Lexar (8gb). Any chance I missed something important? Or is there a possibility that some sticks just won’t work no matter what?
P.S.: WUDT actually starts copying but stops really quick. A few files find their way to the USB stick. Does that indicate… something? (sry for my english)
This did not work for me. I wonder why Microsoft doesn’t just fix this…
The diskpart tool worked great! For those people who can’t understand what to type, here you go:
- Run “diskpart” from a command prompt with admin rights
- list disk
- select disk # (the number of your USB)
- clean
- create partition primary
- select partition 1
- active
- format quick fs=fat32
- assign
thanks very much, Michael, after a lot of search, this is the most clear, simple and reliable article I’ve ever found
In my case the flash drive had been used previously as XBOX 360 storage. Even after formating it again in Windows the WUDT utility would complain. Your tip solved the issue.
My experience just so if you don’t get it to work, you don’t have to go mad and pull your hair out:
I think some sticks just don’t work, no matter what. With two sticks I tried everything mentioned here and then some, but no use. Then, I tried two other sticks and the first one worked right away and the second had to be prepared the way you explained.
P.S.: Might be coincidence but the really cheap stick and the really expensive stick didn’t work. The two working were in the medium price segment.
You are awesome!
nice work – helped with installing windows 8 preview
Thanks. It would be easy if you wrote commands separately!
Thanks for the hint. It appears the page was rendered incorrectly after the last update. I corrected it now.
Works a treat. Getting the unable to copy files error. Tried running through the diskpart steps but would not recognise the USB stick as I was using an XP machine. Tried installing the MS tool on a Win7 machine and retried the steps. After following your series of DISKPART commands the ISO copy tool works perfectly.
Thaks for fixing a very frustrating problem.
Maybe add a note to your instructions that you’ll need a Vista or Win7 machine to be able to perform the commands. Otherwise the earlier comment regarding using the HP tool may be necessary.
thank you so much! you saved my life!
i have been looking for a solution forever and stressing about it.
you are the man!
Great! this really worked. finally. A big thanks!!
Thank you, this worked like a charm. This is the 2nd time i’ve used this to fix the problem
.
so after “list disk” i typed “1″ for the disk 1 and it brings up the commands.. so i typed “clean” and it says “there is no disk selected. please try again”.. help!
Also in my case, WUDT report: “We were unable to copy your files. Please check your USB device and the selected ISO file and try again.” I disabled my free antivirus Avira and all worked well (as Rene Treffer written above). Avira blocked a file named “autorun.inf” written on USB stick and everything went wrong from that point.
Thanks very much – this solution worked for me perfectly.
Thanks for that.
Got me past an annoying issue.
Now I’m off to try it out with Server 2008 R2.
Greatly appreciated.
You rock!!!
Thanks a lot for the advice.
Worked! Thanks a ton!
Hai dude
great job i like this
I hope that people like you multiply..
thank you…
Nice post, save me! THX!
I would register if necessary.
I want to thank you for the tutorial in cmd and why should i even go there
Thank you
Many thanks, you’ve saved my day!!!!!
Thanks a lot man , it did work for me haha , I was getting the ” unable to copy ” error , then I used your steps plus disabled the WUDT to format my USB creating a new register in regedit and it finally creates my Win7 Sp1 usb copy
Thanks a lot. You’re a life saver!
Michael, you’re my new god.
If you are displeased with the Microsoft tool, try the Win To Flash tool from: http://wintoflash.com/home/en/
it works flawlessly for creating a boot-able Windows install usb drive. It also supports other versions of windows like Vista and XP.
Worked. Many thanks for sharing this.
Thank you, found this post by googling, and it solved my problem.
Michael, thx for sharing! Worked like a charm!
cool verry thx mate
Thanks, the post stopped me from buying a new USB stick.
Thanks for saving my lot of money which I am going to spend on more DVDs and USB stick.
Greatest! Thanks alot Michael. You not only saved me a lot of time but also $10 on DVDs.
Dude… _this_ was the best tutorial in a while. Was nearly rippin my hear out. Dunno what happend, suddenly my stuck refused to accept the .iso
After your instruction it works fine again! Thanks a lot!
Big thanks, tried and tried and tried until found this site.
thanks a lot. Great work man
Used HP utility and it works Great now… Great post.
Thanks so much for the clear and informative post, this solved my problem!
I had the same problem. What was strange is that I had installed Win 7 in other computer using the same USB and ISO file; and that I could still do it with another USB. So I formated, checked for errors in the drive, etc. and nothing worked. Then I found your article, and the solution, with the plus of a satisfying explanation of the problem. Thank you very much, my friend!
Worked like a charm. thanks!!!!!_
Thank you very much!
The same problem exact.
Works perfectly. Fixed.
Thanks
Thanks a lot! That was really helpful.
Thanks, greetings from Brazil.
Thanks a lot for posting this! Works fine, had the same “unable
Perfect! It works perfect! Thank you very much! That was really helpful!
Thanks! This solution worked perfectly!
Hey, This is totally works! Thanks a lot!
Thanks mate. I just bought my USB drive and was gonna return it thinking it was no good. But it totally worked.
Thanks for this soloution to a very annoying problem
have restored my usb stick to work as it should, it worked from new but i dont know what i did to break it.
thanks again
Thanks man!!
Microsoft is so messed up they can’t develop a simple tool that uses the command-line they created to install an OS they also created IN the environment they created!!
lol
thanks man, u saved my day…
i was right to suspect Microsoft and search for the solution online…
hello. just tried to do this and i still get the same error. any ideas? bugged Iso or actualy my usb stick done its share of work for this lifetime?
thanks for a great post.
Thanks – this worked perfectly for the Windows 8 developer preview image preparation as well. Much appreciated!
I could not get this to work, I kept getting the same error. So I used this: http://www.pendrivelinux.com/universal-usb-installer-easy-as-1-2-3/
Where it asks for your iso type, scroll way down to the bottom where it says Windows 7 and click that.
Follow directions. Wait. Boom.
Worked! Every drive I tried to install the windows 8 pre-release refused to work. I tried 3 different drives and kept getting errors. As soon as I tried this method it finally worked. I am now installing Windows on my tablet! It’s odd that Microsoft never added the clean option to that program.
Thanks, this worked for me.
A big thank you – first result on google, and worked. Much appreciated.
maestraso me solucionaste la vida muchas gracias
Thanks, it works perfectly. After hours “googleing” the first good advice.
10x man! work like a charm
Mate, I’ve just got to say, this saved my butt. I am trying the same tool with Windows 8 Consumer Preview and couldn’t figure out why it won’t copy. Thanks!
when i type list disk it show only my pc disk and there no usb why is this happening?
You saved my day. THX!
The clean command really did the trick for me. Thanks a lot!
Thanks a lot! Helped me out. All the good for you!
Thanks a lot.just solved my problem.appreciated.
Saved the day! Thanks a lot. I’ve used WUDT a few times before and it worked, then all of a sudden it didn’t. I was driving myself crazy trying to figure out what was wrong… I’ve formatted and reformatted to no avail. Then I came across this post and all the positive responses so I had to try it.
It worked, thanks again.
thank you micheal.
thank a lot bro it worked for me
you rock
Thank you very much for this! It was quite helpful ^^
Problem solved! – thank you a bunch! And wow.. What a crucial bug in WUDT..
Thank heavens I found this article, just like one of the guys here said about plugging the pen drive in the xbox 360 it’s true. I had it in when I was having a Gears of War 3 marathon between two places, so I used my flash drive for my saves. When using this tool to use it for WUDT, it just would not budge. This guide did the trick, but I did have to use the HP USB Format Tool since even DISKPART was telling me “Well your USB is in a pickle right now so…NOPE”.
But after using the HP tool and then WUDT, life was good again. My laptop is finally ready for a trip to Windows 7!
MANY thanks for the guide and to the peoples comments with helpful pointers!
Tank you so much, man. You save me.
Thanx a lot . btw. i killed the autostartprocess under avirafirewall and after that it works perfectly. MANY MANY Thanx again and have a good day
Thanks I was about to bash my head into my screen trying to set up a boot drive to throw some SSDs in!
Thanks, your instructions helped.
Avira was the culprit for me as well.
Just disable the real time protection by right clicking the icon near the clock and you’re good if that’s what is causing it on your system.
Thank you very much…
Thanks
It worked for me also.
Greetings, and thanks for the instructions–they were awesome for a computer-illiterate person! After completing the file copy, I got a message saying that the files was copied…”however, drive is not bootable”. Hmm… any suggestions? I’m hoping to install W7 to my new SSD. Thanks!
thank you sir
Hello, In my case Antivir blocked the “autorun.inf” that did prevent this MS-Tool from working.
I also did format my USB to Fat32 first.
HI! I got a problem: list disk doesn’t show my USB Stick.
When I enter command list volume it’s there. If it doesn’t show in the list I can’t select it and other subsequent commands won’t apply. Does anyone know what the problem is?
Oh yeah, almost forgot. My USB stick is Kingston DataTraveler 4 GB. I’m running WinXP Sp3.
Thanks
For me it was my antivirus software. The WUDT log file was filled with this message: “Error during backup., Usb; Access to the path ‘X:\autorun.inf’ is denied.”. I disabled my Trend Micro AV and it worked like a charm!
The logfile can be found @ Users\\AppData\Local\Apps\Windows 7 USB DVD Download Tool\Log
Thanks so much!
thnx man it worked
Thanks a lot for this post! Helped me out a lot
I used bootsect /nt60 X: /mbr /force
1. My AVG antivirus is turned off.
2. Format with FAT32.
3. Run BOOTSECT X: /nt60 /mbr /force
4. Tried Acronis Disk Director to format & modify partitions.
Above steps have been tried and still DISKPART didn’t show my USB stick. Therefore, I can’t proceed with CLEAN command.
What seems to be the problem?
Please help. Thank you.
Brilliant post. Had this exact problem, knew it couldn’t be the USB drive or the ISO. Originally tried formatting the drive through the GUI format utility built into Windows, but still didn’t work.
Couldn’t work out what was wrong.. This worked perfectly, thanks!
Luke
Thanks a ton,helped me out when i thought i was doomed.
Great job.
deactivate the Virusprogramms@start the Windows 7 USB/DVD
Oh great! I was getting desperate with my flash drive, having tried to burn an image of windows with the Windows 7 USB/DVD tool countless times. Your method works like a charm!
wow, can’t believe this solved the problem. It was a great find.
Thx Dude, it really was time for my netbook to get his Windows reset
Thank you for this… You should make this known to Microsoft because I was on the phone with tech support for 3 hours talking to multiple “experts” and none could figure out why this was happening… One of them did explain how to clean the drive and stuff which I already knew how to do anyways.. My only question was why it KEPT recorruing… They don’t know that if you use the drive in an Xbox 360, you need to go through these steps in order to get it to be used by another program created by them. Cross compatibility between Xbox & Windows sould be pretty close when handling things like “Formatting” — Anyways, thank you for finally making it clear to me what was causing it at least..
thanks! this works every time i need it. i should probably bookmark this for next time.
Thank you for whoever made this tutorial! saved my day! God Bless you.
flawless victory
hey dude.. it worked.. thanks for sharing this..
thank you very much…
Thanks, it works
This does not work for me.
ISO is fine, USB stick is fine, disabled AVG and used the command prompt guide, everything in it’s right place but I’m still getting the same error message.
Perhaps it’s just one of the times where I simply have to give up?
This article has saved me considerable head scratching, thanks!
Haven’t dabbled in command prompt shenanigans in a fair while.
Sean
Hi Rene,
i did everything, not working, so I tryed to disable my Antivir, and now: WOKRING
Thanks. Worked like a charm
Greetings from Malaysia!
Mike, I don’t know about the issues that the others were facing. I was just looking for a way to install Win 7 from a thumb drive & I stumbled across your article.
I tried the steps u mentioned, & it worked like a charm, no dramas at all. I’ve just completed the stages up to the point where you unpack the contents of the ISO file to the thumb drive. So far, so good. Now, I’ll try to install Win 7 on my other computer with the thumb drive. I’ll update the results whether I succeed or not.
Anyhow, Thanks for your tips up to this stage! Cheers!
Hi
thanks a lot dude
Thanks a lot, this works great!
Thanks, worked flawlessly.
tnx man, I’m currently copying files to flash memory, I hope everything goes fine
Thanks!
It is not working for me it stops on 97 or 98 what can i do now please help…..
you’re awesome man
Thanks a lot dear. It worked for me. I am installing on Dell Inspiron Mini
I can’t express my gratitude, thank you really.
Thanks dude. I was surprised my old stick was working and the new wasn’t. thanks, you saved me a trip to the computer store. precise information with good explanation.
Yay! worked!
Disabling antivirus which blocked autorun.inf worked for me. I am using Avira.
Excellent! Worked like a charm! Thanks for posting.
THANKS! You saved my night! Win 8 here i come!
Hey bro thanks it worked
GOD bless you
Would like to comment that after performing the steps
“Anyway, here is what you have to do. Launch a command prompt with admin rights and run the diskpart tool”
You can then just use the Microsoft Windows 7 USB tool – strange, but true!
tyvm for helping me with this issue, I suggest an ammendment to the article regarding the above
Thanks a lot for that trick it works for me
Thank you very much for posting the solution that would otherwise take me too much time to solve myself. +20 to you Michael!
Thanx man! As always, find the solution from Microsoft problems elsewhere. Good for you Michael!
Did not work for me – same old *we were unable to copy your files* message
Very good solution, thanks
Saved me another two days of trying 
thanks!! this worked for me as well! i guess my “verbatim” brand 8GB usb is considered a cheapo haha.
Thanks, you rock!
I was assuming formatting the usb drive with the panel control -> somethingPartitioner was enough.
thanx a lot man
it did work
i had a nrg win 7 image
converted it to iso using poweriso
then used win7 usb tool to create a usb bootable dev
thanks for your article
it avoided wasting a lot of hours investigating on the problem…!
bye
please help,i input the wrong disk number and my 700G files were deleted, is there a way i can retrieve them? thank you in advance sir.
Fantastic advise, thank you.
it works !!! thank you
Thanks!! It solves my problem. Perfect
This worked for me – thanks for posting
Greg
this is top
i was close to buy a new stick
thank you very much
thanks a lot!
This seriously helped me a lot..!! thankyou you brother..!
Your instructions worked on a Sandisk Cruzer 16 GB whereas the MS tool did not!
Worked perfectyl! I Thank you very much!
Thank you, my good man, the advice you provided was accurate and successfully resolved my issue. It seems that the Microsoft provided tool is unable to cope with drives >32GB, as it will not format them with the FAT32 partition table. Manually creating the boot disk using NTFS was the solution. Your guide provided me with the missing link; the bootsec.exe step was one that I had missed.
Thanks alot dude! That did the trick!
Unfortunately, the disk part did not work either. The format quick fs=fast32 resulted in a incompatible file system error.
Simpler solution for me: Use Windows Explorer to format USB Stick with FAT32 (which works interestingly), then start Windows Download Tool again. Now works fine.
Thank you, sir! The Windows USB Tool was giving me fits but this simple fix got the ball rolling.
Thank you very much.
I was having the same problem and your method sorted it out
Thank you very much. Now the program is working perfectly and it’s able to copy my windows 8 iso into the pen drive!
HOW DO I SELECT THE DRIVE I AM LOST HELP PLEASE
Thanks a lot for this valuable information, you saved my day!
Cheers,
K.
I have done all above method on 2 usb with 2 Iso files. but both of them were unsuccessful for me . i have win8 iso file . i dont know what is problem , i have changed the USBs , any help please
Thank you very much! It was helpful for me.
Thanks for that great solution.
Thanks for the commands. The reason why this error message appears at my installation was that avira antivirus tool blocked the autorun.inf of the windows iso-file I tryed to copy to the USB stick. Unchecking this function in the antivirus tool made WUDT doing its job.
Thanks a bunch. Worked perfectly.
Works perfectly.
did the job. nice work. thank you very much!
Thank you very much… Worked perfectly
Just deactivate the “block autorun” function of you firewall and /or anti virus software. i´m using avira antivir as antivirus program and had the same problem. after deactivation of the block autorun function it just went well.. cheers
Flawless victory! Thanks a lot dude
My drive was formatted with the NTFS file system, and this guide steps you through formatting it as FAT32. I guess the Microsoft USB tool is only FAT32 compatible.
Thanks! worked great for me too.
Thank you. Though I’m a bit confused about the magic commands(diskpart, xxx, xxx)
Anyway, this method indeed works.
Thank you very much good sir!
Worked perfectly. Thanks!
Thanks man.. this did the trick
Hello,
Brilliant, I was getting the same error, I followed your steps to clean partition etc. then I used the tool again and it began to copy, thanks alot.
Ryan
Thanks for a very helpful post
Thank you
Thank you so much, it worked!
Very surprised the ‘clean’ command has no GUI access anywhere within windows. Obviously there shouldn’t be anyone fiddling with it willy-nilly, but what common consumer goes into the Disk Management within control panel anyway? Should have been added.
Anyway, thanks a bunch! Worked for me.
Thank you, appreciate it very much!
You sir, are a genius, thank you!
Thanks for this!
Hi Michael..
My USB stick not detected in the command prompt after writing “list disk”. Iam using windows xp sp3
please help me. thank you very much
Thanks, saved my day.
Good grief – thank you for this….just saved me an hour of futzing around.
Thank you, great tip.
