First Cup of Ubuntu
another thing to consider is multiple drives. Make sure your boot drive is the drive with Grub on the MBR as it can be on multiple drives...

I just installed Windows XP which overrides the Grub loader and MBR. I want Grub back. So I am using the initial post in this thread as a guide. I get stuck, however:What does this mean? Does this mean my sda ubuntu partition isn't loaded? I tried mounting it as the intial poster recommended but I failed. Here are the commands I tried:Code:grub> find /boot/grub/stage1 (hd0,5) grub> root (hd0,5) grub> setup (hd0,5) Checking if "/boot/grub/stage1" exists... yes Checking if "/boot/grub/stage2" exists... yes Checking if "/boot/grub/e2fs_stage1_5" exists... yes Running "embed /boot/grub/e2fs_stage1_5 (hd0,5)"... failed (this is not fatal) Running "embed /boot/grub/e2fs_stage1_5 (hd0,5)"... failed (this is not fatal) Running "install /boot/grub/stage1 (hd0,5) /boot/grub/stage2 p /boot/grub/menu .lst "... failed Error 12: Invalid device requested grub>Oh yeah, these are the contents of my fstab:Code:ubuntu@ubuntu:~$ sudo grub Probing devices to guess BIOS drives.

If you want to install grub to the mbr, then "setup (hd0)"..."setup (hd0,5)" installs grub to the root partition.
(hd0,5) is the way grub recognizes /dev/sda6...if your root partition is indeed reiserfs, then:
or if its ext3:Code:sudo mount -t reiserfs /dev/sda6 /ubuntu
The fstab you've posted is from the live cd, not from your installed Ubuntu. If you're able to mount your root partition, this will show your fstab:Code:sudo mount -t ext3 /dev/sda6 /ubuntu
Code:gedit /ubuntu/etc/fstab
May the Ubuntu Be With You!

setup (hd0) doesn't work either:Code:grub> root (hd0,5) grub> setup (hd0) Checking if "/boot/grub/stage1" exists... yes Checking if "/boot/grub/stage2" exists... yes Checking if "/boot/grub/e2fs_stage1_5" exists... yes Running "embed /boot/grub/e2fs_stage1_5 (hd0)"... 17 sectors are embedded. succeeded Running "install /boot/grub/stage1 (hd0) (hd0)1+17 p (hd0,5)/boot/grub/stage2 /boot/grub/menu.lst"... failed Error 12: Invalid device requested grub>

I changed the dir from /ubuntu to /u666 (don't ask):
Code:ubuntu@ubuntu:/$ sudo mount -t reiserfs /dev/sda6 /u666 mount: /dev/sda6 already mounted or /u666 busy ubuntu@ubuntu:/$ sudo mount /dev/sda6 /ubuntu6 /dev/sda6 looks like swapspace - not mounted mount: you must specify the filesystem type

You may want to use Grub's CLI to investigate your computer:

Is /dev/sda1 a separate /boot partition & your root partition sda4 or sda5?
