ubuntu and open suse grub2 vs grub

English Install/Boot/Login

I wouldn’t call it “chainloading” though. update-grub adds kernel entries for direct booting. If you want to chainload openSUSE’s Grub - which is possible too - you have to manually add entries in /etc/grub.d/40_custom. Everything in that file (except the 5 lines at the top) will be appended to Ubuntu’s /boot/grub/grub.cfg after update-grub. An entry to chainload openSUSE’s Grub could look like this:

menuentry "openSUSE 11.4" {
   set root=(hd0,4) 
   chainloader +1
}

Of course you have to replace (hd0,4) with the hd and partition where your Legacy Grub bootloader (stage1) is located.

Solved my problem. Sabayon has a boot loader recovery on their install disk. Repaired the original boot loader and added Osuse. Dont know why Osuse don’t play well with others first ms now linux.

I was kind of in the same situation as the OP.
This worked great, I now have a tripple boot.

THANKS!
