OK I installed in the following order.

Windoze XP
Ubuntu 8.10
Fedora 10
openSUSE 11.1

All show up as selections in the suse grub menu and all boot except Ubuntu. I can't figure out why. It gives an error of a file missing when I try to boot Ubuntu.

Please help!

well obviouslk suse did not read your meneu first file. and load ubuntu. go into you /boot/grub/menu.1st. and configure it. mine is on hard drive hdc. so my grub points to hd2,0.

If Suse was your last install go to YaST and select 'system' in the left panel then 'boot' in the right panel then find the edit menu list. It has been sometime and I am not near my home computer so I may miss a step in my directions. If ubuntu is not listed then the easiest would be to open terminal and type the 'fdisk -l' command and post it so that we can see the layout of your hd. If there is anything you do not understand please ask.

Here is the output of fdisk -l

Hope this helps. Thanks for the help!

In your first post, you indicate you get a message that a file is missing, which file?

You have an entry for Ubuntu in your posted Opensuse menu.lst file so the missing file is the problem. You might try removing the configfile line for Ubuntu by putting a hash mark (#) to the left of it so it looks like:

#configfile /boot/grub/menu.lst

immediately below that line enter "chainloader +1" (w/out quotes) and see if that works. If not, let us know which file is missing.
