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.

Update: If you have problems Windows 7 USB/DVD Download Tool you can try the free alternative Rufus. The most powerful tool for creating a bootable Windows setup flash drive is WinSetupFromUSB.

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.

Windows-7-USB-DVD-Download Tool-WUDT

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!

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:

"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.

Take part in our competition and win $100!

    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.

    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!

    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.

    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.

    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?

    - 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

    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.

    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.

    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.

    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 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!

    Oh yeah, almost forgot. My USB stick is Kingston DataTraveler 4 GB. I'm running WinXP Sp3.

    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.

    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.. 🙂

    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!

    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.

    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.

    Thanks; this got me sorted after a few frustrating failed attempts to create an installer USB stick.

    Didn't work for me. Manually copying the contents of the DVD after using Diskpart does not create a bootable install USB drive. I used UltraIso It prepared the drive in about 4 minutes and it works perfectly.

    Watch out!
    The WinToFlash utility recommended halfway thru the comments, loads a ton of spyware on your windows even when you choose NO, DO NOT INSTALL during the installation.
    OptimizerPro, LiveSupport, Search, etc. Use something else!

    It worked, finally something does!!!!!
    Now I can reinstall Win7, then I hopefully won't get the bootstrapper error message when trying to load MS Office 2013.
    A Win 7 reinstall, is my last resort after reg fixes and uninstalls failed to allow a successful Office 2013 install.
    At this point without a disc, I was super frustrated when I couldn't save to the USB, but am happy that someone knows what they are doing and is willing to help others.

    Great fix. I was re-using a USB that was previously used for Xbox save games; apparently more residual data/settings that could not be wiped.

    One tip: run everything as admin mode for this.

    My flash drive and ISO were too large for FAT32, so I input fs=ntfs instead. Win7 tool is working fine now.

    It did not work for me. I am trying to create a bootable USB drive. I followed disk part steps and then tried WUDT. It again gave the same error. WUDT still try to format.

    Can I do something manually instead of using WUDT?

    Sujay, you can try Rufus. I also wouldn't rule out that your USB stick is broken.

    I'm had the same Kingston DataTraveler 100 G3 8GB.

    After doing the diskpart commands in an elevated command prompt I successfully copied my ISO file using the Windows 7 USB/DVD Download Tool.

    Thanks for sharing this info.

    Just followed this and worked perfect. Like someone posted above, I used the flash drive to boot a Mac OS X. Reason it doesn't work properly after using it to boot Mac OS X is that Mac drives use GPT (GUID Partition Table) instead of the standard MBR.

    Thx but this doesn't work for me because the diskpart utility tool wont "see" my USB removeable flash drive I get to "list disk" and only the combined space of the 2 internal HDD's are showing but If I use list volume then all 3 drives show

    I am using windows xp professional, is this the core of the problem?

    After you prepare the stick with the steps provided, you have to copy and past the contents of your Windows 7 DVD to the thumb drive, and you are done.
