I have a multiboot system in which the default bootloader is legacy Grub. From the Grub menu I can boot into opensuse 12.1 (legacy Grub), Windows 7 or Ubuntu 12.04 (Grub2), etc.
During today's updating of Ubuntu, the screen says:
So I had no choice but to check the dev/sda box and hit Forward.Writing Grub(2) to boot device (/dev/sda7) failed. Continue?
Now when I reboot, I only see the Grub 2 menu. Obviously I unknowingly chose Grub2 as the default bootloader.
How do I change the default bootloader from Grub2 back to legacy Grub as I have before?
Thanks in advance for your help.
