Missing Operative System

when the system starts, the boot loader let me choose the partition to start.

when I choose 1 (which is the ONLY partition on the disk) it says “Missing Operative System” and halt.

now, the os IS on the disk and everything seems to work in the right way (I’ve installed 2 HDD, starting the “missing OS” disk as slave!)

how can I restore the default loader??! (fdisk /dev/hd1 loader doen’t work)

Since you got the screen “choose the partition to start”, first stage boot loader is fine. You need the second stage loader. Try something like this:

dloader /dev/hd0t79 pc2

Check dloader doc for details.
