  1. Hello. Everytime I start up my computer, it says disk boot failure error. Do I have to reinstall everything on the computer?

    You might have to replace your hard drive too

    If your data is valuable, do not reinstall. Get another drive, then use this one as a recovery drive.
    Later you can find out if it is any good, but like Tmagic650, I would worry that the drive has gone bad... at least in the first four to eight sectors where the boot information is installed.

    Check boot ordeer in Bios is set floppy (if you have 1), cd and HD0.

    If it is and using XP, using a valid Windows XP disk, boot from it, press "R". Type "fixboot" and press "Enter". Type "fixmbr" and press "Enter", type "bootcfg/rebuild" and press "Enter".
