Make usb pen/flash drive appear as a dvd to Win 7

Hello, I'd like to make a usb flash drive appear as a DVD drive so that I can use it to create Win 7 recovery 'disk'.

Thanks in advance.

  1. OK, install or repair from the USB pen drive.

    U need this tool – use USB2 port only! Windows 7 USB/DVD Download Tool

  2. Thanks Niko, but perhaps I didn't frame my question correctly or clearly enough.

    I'd like my USB flash drive to simulate a DVD drive. Ie when it's connected Win 7 should recognise it as a DVD drive. This is particularly for the purposes of creating a Emergency Repair Disk. - I am asked to create a repair disk when wanting to restore the computer from an Image file (one previously created from within Win7).

  3. youll need diskpart.. it comes in windows....
    run CMD
    type DISKPART.exe
    And follow these
    select disk # (find the drive of your usb)
    clean
    create partition primary
    select partition 1
    active
    format fs=ntfs
    assign
    exit

    Then, drag everything over from your disk image over to the Disk drive, this makes the usb drive bootable too, so you can run a linux disk or something from it too :)
  4. Making a usb drive bootable is not the same thing as making it appear as a dvd drive. As far as I know, you can't make it appear as a dvd drive, but if your motherboard supports booting from usb, then making a bootable usb drive will work just as well.

    Thanks Hawkeye, but I don't want to boot from a USB stick. I just wanted to make it 'look like' a DVD drive to the os (Win7 in this case). And as you've said, you don't think it's possible to make a memory stick look like a DVD drive, which is a shame as it will mean having to get hold of an external drive just so I can restore the HDD image to my Netbook (the os needs the drive to create a recovery DVD).

  6. What you want is possible this way:
    I used dd.exe (from chrysocome.net) to find & copy the hidden recovery partition:
    CMD> dd --list <shows the device & partition information>
    CMD> dd bs=1M if=<partition name> of=Recovery.img

    I then mounted the partition image as a drive using OSFMount from OSForensics, but there are plenty of other tools.
    The stick drive can be prepared using DiskPart(plenty of pages on how) & the image contents copied over. This creates a full, bootable recovery from the stick drive. But you do need a 16GB drive.
  7. Quick Update:
    Using DiskPart, http://arstechnica.com/business/2009/12/the-usb-flash-drive/2/ says the stick should be formatted as fat32, otherwise you need to use bootsect.exe, which can be hard to find without Win7 Install disk.
  8. Thanks GryphonB, you have answered my question by thinking outside the box. This method clearly gets around the need to have the memory stick 'look like' a DVD drive.
