Red Hat Bugzilla – Bug 38713
kdm corupts MBR and (probably) partition tables
Last modified: 2005-10-31 17:00:50 EST
I have Powerquest Boot Magic installed on my MBR. The first time I asked
kdm to reboot the system, it gave me a list of the partition I could reboot
do from the lilo.conf file. But simply rebooting back to the standard MBR
did not appear to be an option. After selecting a DOS paritition that I
really wanted to, the system rebooted and then hung. After a ctl-alt-del
reboot, I ended up booting strait to the linux partition, Boot Magic no
longer was functioning.
After several attempts to put things back together, and reinstalling Boot
Magic, the (DOS) BM configuration program still isn't working correctly,
and there some as yet undetermined amount of damage to my disks partition
tables. I'm working with Powerquest support to try to determine what is
broken and whether it can be recovered. In the meantime I would warn
people not to use the kdm reboot feature under any circumstances.
If you aren't using LILO, don't ask kdm to configure LILO for you.
Open kcontrol, go System > Login Manager > Sessions, then deselect "LILO >
Show boot options".
You'll lose the feature of being able to specify which OS/kernel you want to
boot next time around because this doesn't work with any non-LILO boot
