    When trying to boot from a USB disk, I get:

    Non system disk or disk error

    What does a non system disk or boor error mean?

    Well, it looks like either:

    Y

    1. our USB boot disk doesn’t have a system partition on it (in other words, it doesn’t have an operating system to boot to)
    2. Your USB boot disk has a disk error (The USB disk might be broken or the system partition has been corrupted)
    3. You may have the boot order set incorrectly – perhaps it’s trying to boot to the hard drive that doesn’t have a system partition on it, instead of booting to the USB disk

    To fix the non-system-disk-or-disk-error, check that the PC is set to boot from USB (BIOS settings). Failing that, try recreating your USB boot disk.
