Rebuilding GRUB

[Tak178]

Hey guys,

Silly me, but I thought I would try to play around with Ubuntu 9.04. Consequently, I got it to run, but still can't configure drivers to work properly. As such, Ubuntu rewrote my MBR, and so it is using the GRUB prefs from the Ubuntu partition. How do I reassert Mints right over the MBR?

Were you using the Ubuntu boot CD? Whatever you did while on that CD, you could probably do with the Mint CD and get similar results.

I think the original poster was talking about an install vs a LiveCD.

It's really quite simple to restore your Mint menu.lst.

1. You need to know what the partition is that Mint resides on (sda2,3, 4 or whatever).
2. Boot to any Linux (even Ubuntu).
3. Initiate the terminal mode.
4. $sudo grub.
5. Assuming your Mint is on sda4 and your mbr is on hd0 : grub > root (hd0,3)
6. grub > setup (hd0)
7. Exit and re-boot.

One additional thing I forgot to mention in my post. By restoring your Mint menu.lst , you will probably loose visability to the Ubuntu ops. If you want to continue to access this ops, you will need to modify your Mint menu.lst to include the Ubuntu ops.

Thank you, everyone!

Since I will installing Linux Mint when it arrives, I am probably going to wait and let the new version rebuild the MBR from the install CD.

I appreciate your info, and I will keep it in case I need it in the future.

Cheers,

from my experience, messing around with GRUB can be very tricky, especially if you don't know what you are doing it can cause little disasters
waiting for the new release may not be the most efficient way to solve the problem, but it will certainly be the safest and cleanest way to handle the problem

Hi ckeep, and welcome. The directions DataMan gave above are good, and they will work from any linux, live or otherwise, so feel free to use puppy.

If, however you get stuck at step 1 of his directions, skip over it and do the following after step 4:

Code: Select all

find /boot/grub/stage1

This will give you the code to use in step 5 (e.g. (hd0,3))
