    I have original win 7 preinstalled, and want to make a bootable/backup copy on usb or dvd but don’t know how…
    Don’t have win7 on usb/dvd or any other drive.

    A quick note, USB 3 ports will NOT work on windows 7 without a previous copy of windows installed / the drivers. They require host controllers, if you’re installing windows 8 via a usb 3 port it should work fine as they have native support. method worked flawlessly for me installing win 7 professional via a usb.

    For those of you still having issues with invalid ISO, this is what i did. Follow IJas intructions.

    1.) Open ISO with PowerISO- Full Version
    2.) Go to File, File Properties
    3.) By Default, UDF is checked. Verify, it must be checked
    4.) Press ok
    5.) Go to file and “Save As”. This will re-create the ISO with UDF enabled and should only take a min.
    6.) Load the re-created ISO With the Windows 7 USB Tool and that should work. It worked for me.
    Good Luck and thanks IJas for figuring it out.

    2nd note: For those of you having NTLDR errors, Try reformatting you USB to FAT32 format, not NTFS.

    I have a question: this tool works on Windows XP too? I mean, if i don’t have installed Win 7, only a Win7 kit, it’s ok?

  6. justin says

    i’m tried as given above but if i select the iso file the following error will display “The selected file is not valid iso file. please select valid iso file and try again later”. when i check the file properties ti shows iso image file.

    ANOTHER POORLY written untested set of instructions.

    Most of us have legitimate versions of Windows on CD. What about instructions on how to get the Windows 7 CD onto the USB to speed up the process??

    Based on the many many comments here, this does not work.
    Thanks for nothing!
