    Addition to clarify previous question:
    Live-drive , meaning, as for diagnostic use. Not to be used for installing Windows, but “running Windows-from the drive”.
    There are loads of tutorials for creating the live disks & USB’s but none for milti-boot (dual/triple boot).

  6. ity_bity_lilo_ME says

    I haven’t made this yet, but I’m going to after I finish typing, but I have a request.
    By using a larger USB drive like a 16GB, Can you make a Dual-boot, or even triple-boot,live-drive?
    Like Windows-7, XP and maybe Ubuntu or”?”.
    And if so , How?

    I tried to make PEN drive bootable with the software but no luck. Even i have to face one more problem. Accidently i choose my another hdd 2nd partition (E). Had two partition (d and e)in the HDD. As soon as it started creating the image i realised that i have choosen wrong drive letter (hdd instead of PEN drive) and hence cancelled the process, since than i cannot see my partition in HDD. there is only one partition (E) shown to the disk. I lost partion D …
    i am using window 7
    was trying to create usb pen drive bootable for XP.
    i had two partition in 500 GB HDD .. 1 (D) -10GB and 2(e)-30gb and rest was unallocated. Now it is showing 465.76gb only with drive letter {E}.

    Please suggest.

  18. smiegel says

    it seems to be working…. my cd drive wasnt/isnt working so this seems to be a great tool.

    thanks to the geniuses behind this website

  19. Dave says

    You can mount your iso. on a virtual drive such as virtual clone ect. then use the virtual drive as the source file.
    (tried and tested success on Win7)

  20. Johnson says

    @KC: You need to write the ISO to a CD first, and not just as a data CD which wont work. This can be done using Nero or similar. (I think windows comes with a program that can do this also).

  21. Johnson says

    For those that on boot up are having problems: Enter the BIOS and remove everything but the USB device from the boot list. Even if priority of USB was higher in boot order or I chose USB device on startup it still attempted booting from HDD which you do not want. Hope this helps a few

  22. KC says

    PLEASE HELP! I cannot get it to work! The WinToFlashTool program keeps saying incorrect windows source file location or something like that!
    I don’t know what is wrong.

    Can you reformat your flash drive back to normal, if i do not need the bootable format.

    I have Windows 7 Ultimate SP1

    If anyone knows how to fix a Windows Update fail that occasionally freezes and must have a ‘hold down’ power off. I hope the recovery will work.

    Thanks you if anyone can fix my problem!!!!!!
