On sda1 I have a common bootloader for all OSs installed. On sda3 I have openSUSE 12.2 installed. On sda5 I have openSUSE 12.3 RC2 installed. On sda6 I have Tumbleweed installed. I had kernel 3.8.1 installed on oS 12.2 and also on oS 12.3 RC2. Everything worked fine. This morning I installed kernel 3.8.2-1 on oS 12.2 (sda3) and it everything went well, No hassles. I then installed kernel 3.8.2-1 on oS 12.3 RC2 (sda5) - and now I cannot boot. All the parameters in the bootloader(s) appear to be OK except when I go to boot into "safe mode" in 12.3 (sda5) I get the error message: Invalid Magic number. What the f*** is "Invalid Magic number"?! *WHAT* number?! Of all the lame-brained, inane, stupid, meaningless error messages to have ever existed this one MUST take the cake! I think this beats whatever Windows ever managed to come with - and that's saying something. The use of "Magic Mushrooms" seems most appropriate here for whoever used "Magic number" in an error message. OK, apart from knowing what this "Magic number" may be all about, any ideas of how I can boot into oS 12.3 RC2 (sda5) just to be able to, say, tun YaST2 to get back kernel 3.8.1-2? I've tried using the Recovery mode of RC2 but I don't know how to get this to boot into sda5. I can always re-install RC2 and take it from there but there MUST be a way to recover from something like this. Does anyone know, please, what can be done to 'recover' my oS 12.3 RC2 installation?

Basil: I have never worked with grub2 therefore this even might not be appropriate (I don't know how grub2 works compared to grub(1)). Just an idea: Earlier I had boot problems as well and it turned out that one of the stage images had problems. I had to reinstall grub using grub shell to fix it. (grub stage images are copied from /usr/lib/grub/ to /boot/grub when grub is installed, in case of grub1.)

To begin, using grub2 everything is now "grub2-<somecommand>" :-) . That's the first and the most easiest thing to come to grips with - everything else remains basically the same. I've looked at what you wrote and found that what is in usr/lib/grub2 is NOT totally copied over to /boot/grub2. I don't know what the process is but 50% of the files are copied over and given the date that they were created in /boot/grub2. But, of course, my problem at the moment is that I am unable to boot into 12.3 RC2 (on sda5) to be able to use any of the grub2 commands or to re-install the kernel. I read a few minutes ago that 12.3 is almost ready so I think that I will wait for this and install this.

While you wait, boot any live media that contains Grub Legacy (I use Knoppix, the granddaddy of live Linux media), then: mount your /boot partition (sda1) to /mnt # cp -a /usr/lib/grub/* (or wherever you find what belongs in /boot/grub) /mnt/boot/grub/ # grub grub> find /boot/grub/stage1 (hd0,0) (hd0,2) (hd0,4) (hd0,5) based upon above output, e.g. (hd0,2) (aka /dev/sda3, your 12.2 /; /dev/sda1, your master /boot) grub> root (hd0,0) grub> setup (hd0,0) quit ensure MBR code is generic (not Grub) ensure only active (aka startable) primary is /dev/sda1 using fdisk or other tool That's all that's actually required, though creating a usable /mnt/boot/grub/menu.lst (if one does not already exist, otherwise edit appropriately) now will ease the next boot. Assuming you don't do menu.lst, then to get into 12.2: reboot grub> find /boot/vmlinuz # ensure what's expected exists grub> find /boot/initrd # ditto, e.g. (hd0,2) grub> kernel (hd0,2)/boot/vmlinuz grub> initrd (hd0,2)/boot/initrd grub> boot You may or may not need to append anything following /boot/vmlinuz, but nothing at all is probably enough to get you going. -- "The wise are known for their understanding, and pleasant words are persuasive."

Thanks Carlos. As the adjusted Subject header shows, I solved my problem - well, NOT by somehow managing to boot into the RC2 installation but by re-installing RC2 and noting carefully what I was doing. And had I done this earlier I wouldn't have created the "Grub2 hell" for myself :-) . I learnt a few things in during this process :-) . It was all my fault by trying to be too smart and doing things ahead of time - which is what wrecked the system. As a VERY brief explanation, I mentioned that I have a "main" bootloader for ALL OSs installed (as btldr) on sda1, with12.2 installed on sda3, RC2 on sda5 and Tumbleweed on sda6. Well, each of the OSs have their *own* bootloaders installed in their root partitions; and you get *these* bootloaders fixed when you fiddle with the individual OSs *BEFORE* changing anything in the "master" bootloader (btldr) on sda1. I jumped ahead of myself, anticipating what will happen when I fiddled with RC2, and manually with btldr in sda1 - which is why I created the "hell" for myself. There is a correct way of doing things when having multiple systems with a main btldr - and I now what this is :-) .
