My aging Amilo Pi 3625 today failed to start up, telling me that it could not find the OS. I have been trying to restore from the backup/restore disks I made when I first got the laptop, but I am getting the almost immediate message "An error has occurred (6)". What does this mean, please, and is there anything I can do? Or does it just mean my computer is dead? I've had to restore from these disks twice in the past, and not had problems. There is no visible damage to the disk, and the disks cave been stored carefully. Please respond asap, I'm tearing my hair out as this is my primary work computer...! Thank you!
