There are two processes here. The first is where GRUB loads the kernel and
boots it. The first root line tells GRUB which fs to mount. The first argument
to the kernel command tells grub what kernel to load.
If your linux kernel starts booting then those settings are fine.
The second process is when the linux kernel boots. GRUB can pass arguments to
the kernel, these are the arguments that follow the 'vmlinuz-2.4.5'.
kernel (hd0,0)/vmlinuz-2.4.5 root=/dev/hda3 ro
This second root parameter is what linux uses to mount its root fs.
On my system I have (in /boot/boot/grub/menu.lst):
title GNU/Linux
root=(hd0,4)
kernel /bzImage root=/dev/hda6 mem=128M hdc=ide-scsi
If your second root is incorrect, linux won't be able to boot. Are you sure you
have the correct partition specified?
Check that your /etc/fstab is correct, the <type> must be reiserfs.
Make sure you have a new version of GRUB, the older ones don't read reiserfs
(but if your kernel is booting then it's working).
If you want to find the correct partition that has your root, you can use
different root(hd0,x) commands in grub and tab-completion to see what files are
on each partition.
Are you using the command line directly? You can enter command-line mode by
pushing c, this is the quickest way to find the correct settings.
The grub .info manual has a lot of useful stuff, eg:
- Command: cat file
Display the contents of the file FILE. This command may be useful
to remind you of your OS's root partition:
grub> cat /etc/fstab
- Command: find filename
Search for the filename FILENAME in all of partitions and print
the list of the devices which contain the file. The filename
FILENAME should be an absolute filename like `/boot/grub/stage1'.
Good luck
