[opensuse] can't install SuSE 11.0 grub in MBR
I installed 11.0 on my ThinkPad T60 and it worked fine. Installed another disrtro and it wiped out 11.0 grub in the MBR. Now I can't boot 11.0. Tried to install 11.0 grub in the MBR thus: "# grub
root (hd0,11) setup (hd0) quit #"
This works with every other distro I ever used except suse. "grub> root (hd0,11) Filesystem type is ext2fs, partition type 0x83 grub> setup (hd0) Checking if "/boot/grub/stage1" exists... no Checking if "/grub/stage1" exists... no Error 2: Bad file or directory type grub>" stage1 is in /boot/grub Can I use the SuSE 11 DVD as a rescue system to boot 11.0? In the old suse installation, there was a choice to boot an installed system, is that still available? jozien -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

The feature was removed. :-( Perhaps you could use the supergrub cd instead. There is another method. No, two methods. One is to boot the DVD into automatic rescue mode, it should be able to repair things. Another is to boot the DVD into manual rescue, ie, into console. Once there, you have to manually mount your system (root /) and boot partition if it exists, for instance in /mnt, and do: mount --bind /proc /mnt/proc mount --bind /sys /mnt/sys mount --bind /dev /mnt/dev chroot /mnt/ /bin/bash --login Once there, you should be able to use your normal Yast in text mode, and try then to restore/repair/whatever grub. - -- Cheers, Carlos E.

But linuxrc still has it. This is from memory (so please cmiiw) but the general steps are something to the effect of; - boot from dvd - choose 'installation' - hit 'abort'/'quit'/'yes I mean it' until you get the red 'an error occured'-screen - hit 'ok' - choose 'start installation' - choose 'boot installed system' At this point linuxrc looks at the partitions and gives you a choice of the ones the are 'regular' filesystems. - choose the 'correct' partition - boot Not very 'flashy', but it does work. It suffers the same weakness as the 'boot installed system' from the installer; You end up with a system running the kernel from the dvd, which in many cases is older than the one on disk. So there are some operations that just won't work properly. But you *can* 'boot installed system' from the dvd.

I have never succeeded in booting installed system from the 11.0 retail dvd using the above method. It throws an error and then the next time you try it hangs on glibc general protection faults.

Interesting. I'll try next time.

The end result should then be similar to the chroot manual route I propossed.

I just booted using opensuse 11.0 dvd rescue system and kexec. I used the mount root at /mnt, mount --bind /proc /mnt/proc, mount --bind /sys /mnt/sys, mounr --bind /dev /mnt/dev and chroot /mnt /bin/bash --login. The next step is simple:- kexec -l /boot/vmlinuz --append=root=[your root] --initrd=/boot/initrd to load the kernel into memory then kexec -e starts the kernel.

I found a better way using kexec in the dvd installation system. Boot into rescue system, init 1 (you must go to single user mode otherwise you will boot with the dvd's drivers) mount your root at /mnt then kexec -l --command-line=root=/dev/yourroot --initrd=/mnt/boot/initrd /mnt/boot/vmlinuz then kexec -e You could probably do this from any console in the installation system, for instance after system repair.

Thanks to all who replied. This I got from alt.linux.suse: "If anything fails, give SuperGrubDisk a chance" www.supergrubdisk.org It worked fine, I booted suse 11.0 and was able to install grub in the MBR. jozien -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Wow extremely nice! This should be a big simple wiki page all by itself with plenty of keywords so it turns up in searches. All related discussion about how to determine "/dev/yourroot" etc should be off in other pages but linked, to keep the recipe above exactly as short and clear as it is. -- Brian K.

Its actually better than boot installed system because you end up with your current kernel, all it does is bypass the bootloader. There is already a wiki page for kexec http://en.opensuse.org/Kexec. If you have kexec package installed and you run the command kexec-bootloader prior to a reboot it skips the bios and bootloader part of the reboot.
