  • Just to clarify... You are installing XP on a USB drive and it fails to boot and gives this error or?

    @dan I thought that might be the case - WinXP does not support installing to a USB drive by default, and will crash if you do so (because it will, by default, disconnect and rediscover all USB as it boots - disconnecting the drive it's running from in the process and causing the STOP you are experiencing).

    BSOD STOP code 0x000007B means INACCESSIBLE_BOOT_DEVICE, which is pretty self-explanatory. The bootloader loads the kernel (otherwise you wouldn't be able to get the BSOD) off USB using BIOS calls, but then the kernel has to switch to its own USB storage driver, which it doesn't have at that point, and crashes.
