Fedora 10 Update killed GRUB

[MAC693]

After a Fedora update Fedora does not boot. It gets to a GRUB prompt and does not echo keyboard input.

I found following steps that should recover the problem.

1) Insert Fedora installation media
2) boot to rescue mode
3) choose language, skip network settings
4) once you are at a shell, type:
5) grub –device-map=/tmp/drivemap
6) quit
7) vi,pico or nano /tmp/drivemap and move sda and sdb around, or perhaps hda.
8) chroot /mnt/sysimage
9) I had checked that /tmp/drivemap had stayed the same by running cat /tmp/drivemap
10) grub –device-map=/tmp/drivemap
11) quit
12) grub-install
13) reboot

8) didn't work. I have not sysimage on /mnt
12) I can not execute grub-install

I am not a Linux expert....need really help.

I am really pissed , because I have a lot of apps on this linux maschine and I dont want to reinstall this stuff.
So...can anyone help me with this problem..

Hello MAC693,

If what you actually saw was "GRUB _" with the system hung and requiring a hard reboot, then that is not unheard of after an update. I don't quite know what to say about the steps that you tried. However, what is usually done for this situation is simply re-installing the GRUB boot loader in the normal and classic way. Why don't you try that?

Hello stoat,

with classic way, do you mean
Linux rescue
chroot /mnt/sysimage
grub-install <devive>

but as I mentioned chroot /mnt/sysimage and grub-install dont work!

[stoat]

Well, another common and popular thing to do in this situation is to download and create a Super Grub Disk. It's a free utility that can boot Fedora when its boot loader is busted. Once Fedora is running, open a terminal and run your grub-install command to re-install GRUB. Or, if you prefer, the Super Grub Disk itself can re-install GRUB for you.

I'll check it....thanks for help

Hi Mac and Stoat. After attempting to install fc10 I ended up with the dubious "GRUB_" also. I had to use the text install method because I have an nvidia video card. Before that attempt, I had the machine working fine with fc8 on the 80G (sdb) drive and XP Pro on separate 250 GB (sda) drive. (I am able to boot the Fedora rescue program (from the DVD) and I do have a "SuperGrub" CD that loads. But, haven't tried anything with either, yet.) So, Mac...Could you let me know how you came out?

this is odd

" also. I had to use the text install method because I have an nvidia video card

10 installed just fine using the gui with my 8 year old gforce 2 card
the network did not work but Anaconda & Gnome worked just fine WITHOUT installing a driver

Thanks to all. I did get F10 working great (so far) ....Had to go back and re-install with putting Grub on sda. I'm guessing my Bios won't even look at sdb unless something on sda tells it to. Don't know much about this stuff...I'm more into routers and switches...But, it works now. (Note: Had to download and install nvidia driver from rpmfusion to get the graphical interface to work. GeForce 7300 LE is my nvidia card. Nvidia driver version is 180.29, if that helps anyone.)..
