    "A disk read error occurred" After installing XP


    Hello

    About 3 hours ago I installed Windows XP x86 on an empty partition. Before the install my partitions were like this:

    C: Windows7
    D: Empty NTFS Partition
    E: Backups Partition

    I've installed XP many times before and I've never had this happen, but when the install finished, suddenly my Backups was C and my Windows 7 partition was E, making Windows 7 refuse to start. I tried to go into XP and switch them back to their original letters using "Computer Management" or something similar under "Administrative Tools", and to do that I had to make the Windows 7 one "active" and switch the letters, but it still wouldn't start.
    The Windows 7 install disk will sometimes detect something is wrong, but it's tried to repair it 3 or 4 times now and still the same thing: "A disk read error occurred, press Ctrl Alt Del to restart".

    Would anyone be able to help me out?

    But have you ever installed XP on a drive with W7 already installed ?
    Did you make a disk image of W7 on your backup drive ?

    Post a shot of disk management.
    You can`t just change drive letters to a partition, they will be pointing to the wrong partition.

    Ah, well the data in my Windows 7 partition and my backups partition is still accessible through Win XP, and even before I changed the drive letters I had that error when trying to start Windows 7
