Unmountable_boot_volume

By souton
Apr 29, 2005
  1. When I started my computer up, I got a BSOD:

    UNMOUNTABLE_BOOT_VOLUME

    STOP 0x000000ED (0x8636A900, 0cC0000032, 0x00000000, 0x00000000)

    I did some research and found that this was not an uncommon problem and to use the Windows CD-ROM and to select R to repair the Volume. But when it searches on my CD I get a message that says:

    The file cdrom.sys is corrupted
    Press any key to continue

    I tried it one more time and got this message:

    The file cdfs.sys is corrupted
    Press any key to continue

    I am at a loss, any help would be most appreciated.
    Thanks

    try not using the first prompt for repair
    let it install then you will get another screen saying it found OS repair or add
    try repair from this point
    sounds like the MBR is corrupt
    remember back it up

    and the computer retarts

    May be a bit too obvious to ask, but what condition is your cd in?
    I'm 90% sure thats not your problem, but figured I'd ask anyway.

    Are you sure you cd drive is working properly? Try another cd drive if you have one installed. If not just check the cables and make sure they are properly seated.

    If you do that and it still occurs, try removing some RAM. Sometimes bad ram causes all sorts of wierd things to happen. Try each stick individually.
