FC-9 boot problem/solution

I installed fc-9 on a friends computer. We updated the system and it
went flawlessly. After rebooting we notice that the kernel had been
updated. I rem out the line for the older version in grub.conf. I should
have first made sure it would worked.
Upon booting it failed with the new kernel. I booted to disk 1 of
Fedora and tried a repair. It didn't see /boot or grub in etc. I don't
know why this is? /boot/grub/grub.conf is were it is located. I was
going to use vi and take the rem out so linux would boot to the older
kernel. I couldn't get there? No boot directory visible. I know I've
done this before and it was there. Any ideas?
I edited grub in the boot process and saw “f'c9” on the boot line.
Edited it taking out the “'”and it worked fine. Once it booted I took it
out for good, but the insures I'll try a boot before just rem it out again.

IIRC, when booting to recovery mode, you still need to manually mount
the partition holding the grub.conf since your current working
environment and root will be the recovery CD, not your hard disk.

If in the newer Fedoras it's mounted automatically for you, check
for something like /mnt/sda1/boot/grub/grub.conf. Otherwise, you'll
have to mount the partition manually.

Hello Jesse:

In Grub:

After having had an OS update installed, the next reboot offers a short
period of time for you to either continue the bootup with the newer OS,
or go back to the previous OS. It may seem wasteful to keep the extra
files around, but this is your insurance policy, for success, on those
rare occasions when the newer OS fails. I believe the OS files that
are installed during an update amount to <100MB.

Good luck to you.
