Problems booting from sdb

Hi
I installed Opensuse on sdb but the os refuses to start.
I would like to start the OSś with the Bios-one time menu.
The flag is staying on sda3 (for windows7) and on sdb2-the boot partition for suse.
I dont know what went wrong, meanwhile, through my experiments solving the problem, I formated by mistake this boot partition.
I guess I have to install the bootloader in this partition again and somehow “tell” the mbr to load from sdb2, is it right?

Maybe is this a UEFI or a BIOS machine?

Itś a BIOS mashine.

Then you are right :slight_smile:
