When starting pc up, i get a message "Disk Boot Failure, insert system disk". I have gone into the bios and disabled the cdrom and still i get the message, so i dug up xp cd and put it in and it goes throught he set up for windows then says that there is no harddrive detected.

I have checked and it is attached correctly. It is a fairly new harddrive which has been working for 3 weeks. Usually when i have ever recieved the mesage with previous harddrives, i would turn off at the wall and restart and it owuld work fine now it doesnt.

Any Suggestions?
