Can't boot in opensuse 11.2

I have installed windows7 than ubuntu 9.10 and than I have installed opensuse 11.2 but after reboot I can only boot on opensuse and windows7 I can’t boot in to ubuntu 9.10. please help me.

You can boot Ubuntu by repairing (or replacing) the entry for Ubuntu that the openSUSE installer makes in the Grub bootloader configuration file. A workable entry for Ubuntu goes something like this:

#Don't change this comment - YaST2 identifier: Original name: none#
title Ubuntu 9.10 booting via symlinks
root (hd0,8)
kernel     /vmlinuz   root=/dev/sda9 ro quiet splash
initrd      /initrd.img

For full info see this: HowTo Multiboot Ubuntu from openSUSE using the GRUB bootloader

If you have difficulty applying that, post here the reply you get from these two commands and we can advise further

  • sudo cat /boot/grub/menu.lst
  • sudo /sbin/fdisk -l

I had try to repair ubuntu by live cd before your reply and now I am not able to boot in opensuse but I can boot ubuntu and windows now give me exact reply so I can boot in all this opnsuse, ubuntu and windows os.please…
THANX…for previous reply…

The sequence would be
(1) boot into openSUSE
(2) reinstall the openSUSE bootloader
(3) put the code into the menu.lst file that we discussed above for booting Ubuntu from openSUSE’s loader.

For (1) use this tutorial: HowTo Boot into openSUSE when it won’t Boot from the Grub Code on the Hard Drive
For (2) use the Appendix in this tutorial
For (3) use this tutorial: HowTo Multiboot Ubuntu from openSUSE using the GRUB bootloader
