Old XP Pro box (SP3 - all updates) froze, which was not unusual. Reboot yielded Boot failure message. Restart with Boot floppy (last updated 5/28/09) gets me a message saying that Windows could not start because of a disk hardware configuration problem & that it could not read from the selected disk. Could not start in safe mode - I just got multiple Boot failure messages. I checked the floppy drive cables. After pressing on all connections, safe mode seems to work. Now the PC does not recognize the USB keyboard. Crap! Try PS/2 keyboard - it works. However, restarts in safe mode still yields the disk hardware configuration message. I don't have a rescue CD, but do have the original Windows XP CD. I am out of ideas & think I have a problem. Help!
