Ubuntu 11.10's cannot seem to see my SUSE reiserFS. I am trying to add SUSE to Ubuntu's grub menu.

I have tried editing the 40_custom. When I run update-grub I get "can't find an ext2 filesystem on dev loop0". My SUSE is on it's own HD at /dev/hde. Update grub seems to find the SUSE ext2 partition at hde1, but errors out with the above error after. Unless I am wrong it seems to be assuming the SUSE hde3 partition will also be ext2 rather than reiserfs.

I have search the forum and found a suggestion to run reiserfsck, but it said there were no errors. Anyone ever added SUSE 9.1 with reiserfs to a Ubuntu 11.10 grub menu?

Do you have the reiserfsprogs package installed in Ubuntu?

Yes, had to to run reiserfsck

Post the output of:

Are you insmod'ing reiserfs ?. Unlikely to work without it (although I haven't worked with reiser since before reiser4 came out, i.e. well before grub2).

Hi
I had a similar problem between Ubuntu and Mandriva when Cannonical have switched to Grub2 and Mandriva clinged to Grub1.
I have a collection of Debian/Ubuntu like distros on my multiboot, plus a Red Hat family member.
In my case, the grub menu goes on displaying the partition with Mandriva but when I try to boot it >> kernel panic ;-((
I had found a solution : booting from Super Grub CD and I could choose my distro, alas, after an update, it is now impossible to boot on Mandriva.
I have Ubuntu 10.04, MacUbuntu, Voyager 11.10, Puppy Linux 4.3.1 and two great French projects, Hybryde EldoradOS based on Ubuntu 11.10, Hybryde Evolution 12.04 on the multiboot and with many updates coming for every distro, i have given up trying to use Mandriva.
Now I start another machine to enjoy it.
I don't know why, but .deb and .rpm distros seem to be quarelling all the time ;-)
