I made a robot which has a hard-disk inside and also a disk drive. After assembling the robot, I am inserting a floppy through the disk drive and installing openos in the hard drive. Then later the robot is booting from the hard disk just fine. THe problem is, when ever I am using pickaxe on the robot to take it to another place, it stops booting. I am getting this error: Unrecoverable error, computer halted. Any what I am doing wrong?
