Re-Install of 9.10 Results In Failure to Boot Grub

[brianafischer]

I have been working on re-installing Ubuntu 9.10 for the last 4 hours. I have made my way through multiple issues, and finally made it through the install process. Now upon reboot, grub fails to boot into Ubuntu.

Issue #1
GRUB does not load linux, upon startup of the computer I get the following error message:

GRUB loading.
error: no such partition
grub rescue>

Issue #2
Cannot seem to repair grub from a live CD.

Please help! My previous install was on /dev/sdc4 which I assume is where grub is currently looking. When I re-installed Ubuntu, I deleted and created a new partition which is why I assume /dev/sdc5 was created.


Is there a way to change /dev/sdc5 to /dev/sdc4?
How can I fix grub?

Let's not assume, let's see exactly what your setup is.

Let's get a better look at your setup & boot process. Boot the Ubuntu Live CD/USB. Choose "try ubuntu without any changes", when the desktop loads come back here and use the link in my signature to download the Boot Info Script to the desktop. Once on desktop open a terminal and run this command
sudo bash ~/Desktop/boot_info_script*.sh This will create a RESULTS.txt file on the desktop. Paste the entire contents of that file back here. Once pasted highlight all text and click the # sign on the toolbar to place code tags around the text.

Hi, I am not the original poster but I have a similar problem and here's the info on my system, maybe you can help me. The symptom is that it's stuck on "Grub Loading" and seems to be looping with disk access every 5 seconds - this at the 1st reboot after a fresh x64 install.

Any help is GREATLY appreciated!

As you can notice from the top of the result of that script, you have grub2 both on sda and sdc. Always when installing with multiple drives make sure you know where are you installing grub.
The grub2 installed on sda might work (it's looking at /dev/sdc5 as it's supposed to) but you might be booting the other one.
The grub2 on sdc definitely will not work because it's looking at /dev/sdc3 not sdc5.

What you should do:
1. Decide which drive you want to use as boot and set it as first option in BIOS. Lets asume that's sdc.
2. Start with the LiveCD and instead of the commands you tried in your first post, open terminal and do:


sudo mount /dev/sdc5 /mnt
sudo grub-install --root-directory=/mnt/ /dev/sdc

See if that will work. If you decide to install grub2 elsewhere, change the /dev/sdc from the second command into /dev/sda or whatever.

[darkod]

@keforex
You have similar situation, even more complicated.
Grub2 on sda, grub1 on sdc and syslinux on sdd. Why so many bootloaders?
The previous advice is applicable to you also. You should use the commands:


sudo mount /dev/sdc1 /mnt
sudo grub-install --root-directory=/mnt/ /dev/sdc

And make sure sdc it the first drive in boot order.

[presence1960]

+1 darkod! BTW syslinux bootloader is from a bootable USB/flash drive which was plugged in when the script was run.

That didn't seem to work.


ubuntu@ubuntu:/mnt$ sudo grub-install --root-directory=/mnt/ /dev/sdc
grub-probe: error: Cannot find a GRUB drive for /dev/sdc5. Check your device.map.

Auto-detection of a filesystem module failed.
Please specify the module with the option `--modules' explicitly.

It appears the device map is empty:

ubuntu@ubuntu:/mnt$ sudo ls -l /mnt/boot/grub/device.map
-rw-r--r-- 1 root root 0 2009-11-30 02:19 /mnt/boot/grub/device.map

Any additional help is appreciated! Also, how can I remove grub from a drive?

TIA

[darkod]

For the second command try this modification:
sudo grub-install --recheck --root-directory=/mnt/ /dev/sdc

[brianafischer]

That worked great, thanks for the help!


ubuntu@ubuntu:/mnt$ sudo grub-install --recheck --root-directory=/mnt/ /dev/sdc
Installation finished. No error reported.
This is the contents of the device map /mnt//boot/grub/device.map.
Check if this is correct or not. If any of the lines is incorrect,
fix it and re-run the script `grub-install'.

Excellent! This did work perfectly - thanks a bunch, I really appreciate the help.

The only thing I've lost was the nice looking mandriva grub menu I had before. Any hints on restoring and/or creating a grub menu that is a little more pleasant to look at? --Thanks!!

[darkod]

Glad you got it working, both of you. For changing layout of the grub2 menu, try googling for "grub2 tweaks", or similar, but not sure how many tutorials are out there yet. Also try searching for "grub2 colors", if that's what you mean by more pleasant, changing the colors used.
Grub2 is fairly new so it might take some time for people to create nice tweaks for it.
The main thing is that it's working fine, and is able to add all OSs that finds on your computer.
