Problem Description
After doing a RecoverEDGE restore, I get an error message saying "NO OS" and the system won't boot.

Cause
The boot track and boot record have not been laid down properly on the hard drive.

Solution
Boot from the recovery diskettes and invoke an operating system shell. Execute the following commands:
dparam -w
dparam /dev/rhd00 `dparam /dev/rhd00`
dd if=/etc/hdboot0 of=/dev/rhd0a
dd if=/etc/hdboot1 of=/dev/rhd0a bs=1k seek=1

After the boot files have been written, exit to the RecoverEDGE menu, press F2 to power down the system and then reboot from the hard drive.
