You can:

to get a list of partitions and partition types. Hopefully you can identify which ones are /boot, swap, and /


Done - no problem.  There's /, /home, and swap.


the reason grub didn't work, was because it couldn't find the /boot partition while chrooted.

if still in rescue mode:

mount /mnt/sysimage first, then mount /mnt/sysimage/boot with the boot partition, THEN chroot /mnt/sysimage and grub-install should work

But there is no separate /boot partition. The /boot directory lives in /. I used to make a separate /boot partition, but was told a while back (perhaps 2 years or so) that this was no longer necessary.


You might also want to check to see if the system will boot after /boot was fscked, and failing that, to see if the rescue would now work properly.

Running fsck on / did nothing.

Other things to look for:

after mounting /mnt/sysimage and /mnt/sysimage/boot

does /mnt/sysimage/boot/grub exist and have a grub.conf in it?

It does exist, and doesn't look corrupted in any way. Just for the sake of thoroughness, I changed the "kernel" line to point to /dev/sda1 rather than the device ID. No dice.

install-grub as described does not attempt to repair a broken grub.conf

Thanks for your patience, and help,
