RC1 partition not included in the new boot loader

English Install/Boot/Login

Somehow, the RC2 installation didn’t include the partition with installed RC1 in the new boot loader.
I tried Boot Loader → Propose New Configuration and it didn’t help. Simple copying of RC2 section with the partition number shift doesn’t work either.
How to add that partition to the boot loader?

So if you install openSUSE 12.1 RC2 into a separate partition from RC1 and you want the ability to boot from both RC1 and RC2 and the grub boot loader is loading the grub menu.lst from RC2, then you need to mount the RC1 partition. Load up the old /boot/grub/menu.lst that caused RC1 to load and add the single standard load of RC1 to the new /boot/grub/menu.lst you are using now as a new boot menu option in RC2. If both RC1 and RC2 exist on the same boot drive, the new entry will work straight on. If they are on separate hard drives, you must make sure the device.map file of RC2 shows both hard drives and that the HDx setting from the grub menu option for RC1 is correct now for the new device.map in RC2. Of course, one would wonder why you want to boot both RC1 and RC2 and further, I think you missed something during the install of RC2 as you should have been able to over write the old RC1 if you wanted to do so.

Thank You,

The old menu.lst is overwritten.

The reason for booting RC1 was that system had already been tuned. I’ve got an image of 11.4 too, which I’d like to boot some day. I hope it won’t be difficult to do.

I didn’t want to overwrite RC1. RC2 was installed on another partition of the same drive.

Not at all.

Thank you, poor soul, for trying to help me.

I think I’d better have a read about grub.

If you know the partition it’s on
Use code like this (adjust accordingly)

###Don't change this comment - YaST2 identifier: Original name: SUSE###
title openSUSE 12.1
root (hd0,7)
configfile /boot/grub/menu.lst

I used the adjusted code. The result is:

Error 15: File not found.

/boot is on a separate partition. I probably should have mentioned it earlier.

Finally I plainly updated the RC1 system from RC2 DVD. Now both partitions are bootable.
