Fedora 9 - Update - Grub Black Screen

[soggyoreo]

Hello,
I upgraded from F8 to F9 today using a dvd iso image. Everything was working fine (after a few minor fixes) and I decided to do a yum upgrade. After the yum upgrade and a reboot I am now looking at a black screen with 'GRUB' in the top left corner with no ability to type or do anything. I assume that there was a kernel change of some sort that occurred and somehow goofed up my GRUB.

Im just wondering if anybody else has came across this and found a fix? Ive been web surfing for hours trying to get a reliable solution but have came up empty handed. Im going to continue searching in cyberspace and will reply back if I find a solution.

Cheers.

ok, this was able to get fixed.

i was able to pop back in the fedora 9 dvd and go into recovery mode to get a prompt.

I had to chroot /mnt/sysimage to be able to run 'grub-install /dev/sda' in order to restore my grub loader. All now works like a charm. I hope this helps someone.

Hello,

The scary thing about this is, it happened to me later on.
I mean, I have several machines I updated from F8 to F9, it all worked without any particular issue, then after the last kernel update (2.6.25.3-18.fc9 to 2.6.25.4-30.fc9), grub was dead upon reboot.
This happened to 2 of my machines and I had to rescue it as described by soggyoreo (with some more complications on one due to raid system and a messed up partition table).
Anyways, I hope it is not as common as it looks, because otherwise there might be a lot of people out there working in rescue mode... Up to now, both machines on which it happened were dual boot with windows XP and F9 x64.

Cheers

This happened to me on two machines after I did "preupgrade" on them.
You need to run the install disk in rescue mode and
run grub-install or use the grub shell to reset the grub to the proper place. I think this
problem was a one time thing with preupgrade (it's a new Fedora
feature just started in common use for F9). Also not all of my preupgrade's
did this, there must be some set of requirements to be hit by this one.
