Grub

Why is that the SUSE grub doesn't pick up other OS (besides XP) when trying to set it up through yast? FC4, uBuntu and I think Mandriva grub certainly picked up the other Linux distros on the machine.

I am trying to add an installed uBuntu onto the grub menu.lst

Code:

# Modified by YaST2. Last modification on Thu Feb  2 19:33:56 SAST 2006

color white/blue black/light-gray
default 0
timeout 15
gfxmenu (hd1,0)/boot/message

###Don't change this comment - YaST2 identifier: Original name: uBuntu (/dev/hdc8)###
title uBuntu 
   root (hd1,7)
   kernel /vmlinuz root=/dev/hdc8
   initrd /boot/initrd.img

There are other entries that I have not included. The Mandriva that is on hdc6 has root(hd1,5) and boots without a problem.

kernel /vmlinuz root=/dev/hdc8
initrd /boot/initrd.img

You must add (hd1,x) in front of /vmlinu and /boot.
x=number of partition-1, where /boot is placed.

Yeah that's exactly what I did. That's the format the Mandriva entry has and I copied it.Interesting that both the vmlinuz and initrd.img are on the / directory rather than /boot (where the other 3 distros have them located).

But that still doesn't answer the question of why SUSE never seems to pick up other Linux distros (when using YaST). Or am I doing something wrong?

Given our freedom in Linux to use partitions any way we like, I'm not sure how grub could discover other installs unless they were already configured in /boot/grub/menu.lst.

Suse does not add other Linux distros to the boot menu.

FC4 and uBuntu picked up that there were other Linux distros installed. Why not SUSE?

When I installed SuSE 10.1 RC1, it recognizes that I had FC5 and FC4 in my system, and created the corresponding entries in menu.lst:

On the other hand, it didn't recognize Gentoo, I had to add it manually. I believe this is because I don't have a vmlinuz file in the /boot directory of Gentoo, just 2.6.15-gentoo-r7.

As far I can tell SuSE do recognize other Linux distros.

victorh,

Thanks for setting us all strait with the facts to back it up. I'm looking forward to the final release of 10.1.
