mpwalter, I hope you have a good boot floppy/cd and a backup, because this can get messy :) Actually it shouldn't be any risk at all, only boot sectors will be changed, and if you can boot a grub floppy you can always recover.
- I am not sure if it's possible to use stage1 from Mandriva and stage1.5 from Ubuntu, but you can try. - the grub command "install" allows to choose any stage1 file. Try "help install" - the MBR is (hd0) - you can specify "full path" to a file, for instance if your have set root to Mandriva and needs Ubuntu menu.lst: root (hd0,4) configfile (hd0,2)/boot/grub/menu.lst This would be what I asked for in (2) in my previous post, and I suggest you try this first, since it doesn't change anything on the disk. Of course, boot into the Mandriva grub before running these commands. Then I was thinking something like this for experiment (1). root (hd0,2) install hd(0,4)/boot/grub/stage1 (hd0) (hd0,2)/boot/grub/stage2 p (hd0,2)/boot/grub/menu.lst This should install the Mandriva stage1 to MBR and link to the Ubuntu stage2 and menu.lst I am new to the "install" command myself, and still find the stage1.5 vs stage2 a little unclear, but if you run setup (hd0) you can see what the default install command is, to get an idea.
