error disk...press ctl.Alt.Del. to restart
What is the complete message? Without the dots after disk...????
Did you do a CHKDSK? You may have a BAD HARD DRIVE, CHKDSK will tell you that.
You could also try changing option in the BIOS to defaults (or "optimized default" if this is an option) first.. if this works, then great. note that sometimes defaults are to boot from CD or a floppy first, so if this is the case, change the boot order to have the hard drive go first.
