Load Error! Press a key to reboot

If the computer after power on is checking the drives ie the CD and/or floppy to boot from then it is a software problem. You need to put in your recovery CD/disk and hope fully it will allow you to just fix the errors within the boot up files and not have to install os.

Your norton could help - try booting from that or the ones you produced by using Norton.

If you have to reload then do not format just save old - it should give you that option.
