Just installed openSuSE, but no grub offered. Where are my other OS's???

And another odd question:

Can I make a partition JUST for GRUB, so that grub is not compromised whenever this situation arises:

...try to repair the MBR for some reason (by running fdisk /MBR from DOS prompt), you will erase the GRUB and render all systems listed in the menu.lst unbootable. (Quoted from GRUB bootloader - Full tutorial @ http://www.dedoimedo.com/computers/grub.html)

...and so that the current situation (with installing Suse) can be remedied...

???

there has to be a bootloader installed in the MBR of your /dev/sda . This bootloader can start either all Operatingsystems or another bootloader installed on in the Bootsector of a partition, for example /dev/sda1. If you want to start Windows, you have such a situation, look at my example from my system how Windows is started.

Am i reading correctly, that I can install grub from my Kubuntu LiveCD???

That should be possible, but be aware, if installing Grub legacy, that there must be anywhere a menu.lst file in an installed distribution.

Don't ever repair an MBR from dos (with a Windows-CD) this is nonsense!!! Look here: http://www.linuxquestions.org/questi...he-mbr-850261/

One can clean the MBR with

Code:

dd if=/dev/zero of=/dev/sda bs=446 count=1

and then reinstall Grub or Lilo respectively.

Man, you rock!

But I ended up fixing everything by...

Backing my FAT32 files, Gparted and zapped all partitions, except my faithful Kubuntu. Then I re-partitioned (with more organization this time), and finally re-installed Ubuntu on a partition, so that I'd get a bootloader back.

Can't find a legacy to work with. The Ub's n Kub's have grub2.

And, Im not so sure how to get to the proper console for executing the grub commands.

Noobz... hee hee!

it seems you'll have to give Grub 2 a try. Read the documentation carefully, it is different from Grub 0.9?

just open a terminal. The preliminaries which where necessary when you chrooted into your environment are now not necessary.
