Hi All,
after not finding any solution for my previous FC2 install(couldn't load X system), I went ahead and did a fresh install of FC3 on to another partition. I didn't create another boot partition, as I was thinking I could either redirect grub to the boot dir for the new install or copy the dir/files onto the existing boot partition. Which way would you do/have done it..? Cheers.
new install = /dev/hda5
boot partition = /dev/hda9
old install = /dev/hda12
I usually install with multiple partitions/logical volumes anyway.
I assume that your entire new installation went into /dev/hda5 and you didn't tell the installer to re-use the existing /boot partition in /dev/hda9?
You can configure your existing FC2 grub to chain-load the FC3 grub
from /dev/hda5, or you could copy the grub.conf kernel entries from your
FC3 install into your FC2 grub.conf. I would do the former rather than
the latter, because the latter would require you to repeat the operation
every time you upgraded the FC3 kernel.
If you post the output of "fdisk -l /dev/hda" and your FC2 grub.conf file, you might get more specific help.

here is what was asked for. FC2 grub.conf and fdisk output,

Paul, I also tried to point grub to the partition like below, but, it generated errors,
root (hd0,4) filesystem type unknown, partition type 0x7
setup (hd0)
Error 17: Cannot mount selected partition
Didn't you install grub in /dev/hda5 during your FC3 install? If so, why are you trying to reinstall grub?
Don't un this, as I can mount the partition under the old install like so,
mount -t ext3 /dev/hda5 /mnt/hda5
And, I also don' un why it shows as HPFS/NTFS when I formatted as ext3.
The partition type entries in the partition table don't have to accurately represent the filesystems those partitions are formatted with, but it causes some confusion (e.g. for grub) when they don't. You can use fdisk ("t" command) to fix the partition types. Did you delete a 4GB NTFS partition and use the space to install FC3?
If you installed grub in the root partition (/dev/hda5, not the MBR) during your FC3 install, you should already have grub installed in (hd0,4) and the following addition to your FC2 grub.conf should be sufficient to run it:

Hi All,
Paul, I got the following at boot,
Error 13: Invalid or unsupported executable format
I also made the change with the t command in fdisk, and made the ID = 83. I definitely have a /boot dir on hd4. Cheers.
So you probably did not install grub on /dev/hda5 when you did the FC3 installation.
below is the output of the boot dir on hda5,
total 2.6M drwxr-xr-x 3 root root 4.0K Mar 12 21:45 . drwxr-xr-x 23 root root 4.0K Mar 7 23:19 .. -rw-r--r-- 1 root root 0 Mar 12 21:45 bootdiroutput -rw-r--r-- 1 root root 50K Nov 3 04:53 config-2.6.9-1.667 drwxr-xr-x 2 root root 4.0K Mar 7 23:20 grub -rw-r--r-- 1 root root 384K Mar 7 22:58 initrd-2.6.9-1.667.img -rw-r--r-- 1 root root 698K Nov 3 04:53 System.map-2.6.9-1.667 -rw-r--r-- 1 root root 1.4M Nov 3 04:53 vmlinuz-2.6.9-1.667
Cheers.
P.S. bootdiroutput is the file created that contains this output.(if that makes any sense).
Try booting from the FC3 rescue CD, get to the command prompt, and do:
# chroot /mnt/sysimage # grub-install /dev/hda5 # reboot
See how that goes.
Paul.
