Description of problem:
Installing Fedora 9, and it's associated GRUB to the MBR, on dual-boot system (in attempt to make it a tri-boot system), with a pre-existing and functional Debian 4 and Ubuntu 8 OS issues no errors.
But upon reboot, fedora 9 GRUB fails to correctly detect and boot Debian and Ubuntu (which previously dual-booted from the MBR successfully). Manually changing GRUBs lst file and rebooting does not fix the problem. GRUB reports and invalid boot sector for both.
Overwriting GRUB with the Debian distribution of GRUB in the MBR makes Ubuntu and Debian accessible again, but fails to boot Fedora 9. Seems that the three cannot co-exist in the boot loader.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Load Ubuntu 8, and Debian 4 on different partitions.
2.Use either Debian or Ubuntu GRUB boot laoder to boot them (it does not matter which one).
3. Load Fedora 9 on a separate partition. Overwrite the GRUB boot loader with the Fedora distribution GRUB.
4. Then try reinstalling the Ubuntu/Debian GRUB boot loader for the second problem.
Could not access Ubuntu/Debian parititions.
A successful GRUB install and tri-boot system.
Installed on a 2 year old Dell Dimension Intel Dual Core with 1 gig of memory, where Fedora 9 alone runs perfectly.
Thank you for the bug report. This looks like a subset of bug 334701, so I'll mark this as a duplicate and ask around about what to do about this issue.
