Installed F9 after CentOS, can't boot CentOS now

[drokmed]

EDIT: Man, my brain is offline today, don't know why I'm struggling with basic stuff.

I booted F9, mounted the old centos boot partition, fetched the boot parameters from the old grub, and added them to the fedora grub menu.

The only problem with this solution, is every time centos upgrades the kernel, I'll have to manually fetch the entries from the centos grub and add them to the fedora grub. Oh well, it works.

====================

Hi all,

I'm having trouble with grub, booting into the CentOS partition.

PC has three OS's: Windows XP, CentOS 5.2, Fedora 9
- Installed XP first, 50G partition on /dev/sda1
- Installed CentOS next, 50G partition on /dev/sda2 and swap on sda3 (4G), grub on MBR
- Installed Fedora last, 50G on sda4, using same swap as CentOS (sda3), grub on MBR (replaced CentOS grub)

I have overwritten grub before with other distro's grub, never had a problem. Grub can still boot into Fedora and XP fine.

From grub, when select CentOS, gives:

  Booting 'CentOS'

rootnoverify (hd0,1)
chainloader +1

Error 13:  Invalid or unsupported executable format

I would be grateful for any suggestions.

Thanks,

Daryl

Hmm upon further review, I should have installed centos grub on /dev/sda2. I need a way to do that after the fact. damn

title CentOS
      root (hd0,1)
      configfile /boot/grub/menu.lst

is probably the easiest way.

Re-installing grub is easy, you can use the install DVD and type 'linux rescue' then follow

or you can use any LiveCD and do

I didn't think of that!

Damn, I'm not thinking right at all today... I'm gonna screw something up if I keep going like this!

Time to get drunk, and start the weekend!

Wheeeeeeeeeee!!!!!!!!!

Captain'n'cokes are on me!

Hello, I use a separate grub partition and install every/any distro to the root partition. I use chain loading so that the grub partition just hands off to the distro's boot loader. It works really well.

I suggest trying that. It minimizes boot issues. Well, for me, it does. I've done it twice on two different drives from scratch. I'm just learning a few more things but so far, so good.
