Need to reinstall grub from install disk - Help please

[goldstar1]

I screwed up...

I'm running x86_64 and was trying to improve the looks of my grub splash screen, using various methods on this forum.

I removed grub via package manager and now I don't have a boot loader.

I am right now communicating to this forum using my install disk and what I need to do is install grub onto my hard drive.

How do I do this?

TIA

Boot from the LiveCD.
If you know the "device name" of your linux partition (e.g. /dev/sda1) then skip to step 3. Otherwise, open a terminal (Applications>Accessories>Terminal) and type

sudo fdisk -l
(note "-l" is a minus lowercase L).
You should see some output like this:


Device Boot Start End Blocks Id System
/dev/sda1 63 112454 56196 de Dell Utility
/dev/sda2 112455 10602899 5245222+ b W95 FAT32
/dev/sda3 * 10602900 51568649 20482875 83 Linux

The device name is in the first column, the partition type is on the right under the column entitled "System". Find the line with partition type "Linux" and then find the corresponding device name. In the above example, /dev/sda3 is the device name of the Linux partition.

Type

sudo mount /dev/sda1 /mnt

Replace /dev/sda1 with the correct device name for your Linux partition.

Mount the dev and proc directories:

sudo mount --bind /dev /mnt/dev
sudo mount --bind /proc /mnt/proc

Change root to /mnt

sudo chroot /mnt
Install the grub package

apt-get install grub
copy GRUB images into the /mnt/boot directory and install the stage* files into the MBR and succeeding sectors

grub-install --recheck /dev/sda
regenerate menu.lst

update-grub

[goldstar1]

Thanx for your quick reply --it seems that gfxboot is stopping me hold on...oops!



root@ubuntu:/# grub-install --recheck /dev/sda
Probing devices to guess BIOS drives. This may take a long time.
The file /boot/grub/stage1 not read correctly.


Should I continue on here?

I would just boot Ubuntu from the Live CD. Once inside there:


sudo apt-get update || sudo apt-get purge grub || sudo apt-get install grub

[goldstar1]

I'm getting some errors here...

You having DNS issues I bet.


cat /etc/resolv.conf

post your results please;)

[caljohnsmith]

Before you chroot, you should copy over your /etc/resolv.conf file into your chroot environment:

sudo cp /etc/resolv.conf /mnt/etc/resolv.conf
And then try chrooting. Let us know if that helps with your "unresolved host" problems.

Hum...I don't know what this means...

Have you tried:


apt-get clean && apt-get autoremove grub

then:


apt-get install grub

[goldstar1]

Here it is...

It's a DNS issue. Add your DNS servers inside your network manager. It should do the trick.

[goldstar1]

Okay here's what I've done and it seems we are getting closer...

ubuntu@ubuntu:~$ sudo mount /dev/sda1 /mnt
ubuntu@ubuntu:~$ sudo mount --bind /dev /mnt/dev
ubuntu@ubuntu:~$ sudo mount --bind /proc /mnt/proc
ubuntu@ubuntu:~$ sudo cp /etc/resolv.conf /mnt/etc/resolv.conf
