I had Vista installed after SUSE which then resulted in the Grub disappearing. Now after getting the solution on how to re-install Grub from openSUSE site, I get the boot menu but my SUSE linux won't boot. The solution was as follows (so anyone who's familiar, please help out):

In rescue mode:
I enter ----------------------> grub
Computer returns like this------> grub>
I enter ------------------------> find /boot/grub/menu.lst
Computer returns like this------> (hd0,6)
I enter ------------------------> root(hd0,6)
Computer returns like this------> File system type is ext2fs, partition type 0x83
I enter ------------------------> setup(hd0)

Then I see 4-5 lines like this: checking if /boot/grub/stage1 exists...yes
Computer finally returns: succeeded...Done

I enter -----------------------> quit
I enter -----------------------> reboot

____________________________________________________________________

However, upon booting I get the following error message on screen a few seconds before the boot menu appears: "root(hd0,5)/boot/message: file not found"

Then the boot menu appears, and when I choose SUSE I get the following error: "Error 17: cannot mount selected partition"


Help will be greatly appreciated.

can you copy and paste /boot/grub/menu.lst

We need more info...

on grub prompt, enter
to see available partition.

You can see available root by typing root ( on grub prompt followed by TAB. (don't miss the bracket)

If you miss the bracket, grub will give you 'root and rootnoverify' options

Entering "geometry (hd0)" on grub prompt I get the following:
__________________________________________________________________
drive 0x80:C/H/S=7296/255/63, The number of sectors:117210240, dev/sda
Partition num:0, Filesysyem unknown, partition type 0x7
Partition num:1, Filesysyem unknown, partition type 0x7
Partition num:5, Filesysyem unknown, partition type 0x82
Partition num:6, Filesysyem is ext2fs, parttition type 0x83
Partition num:7, Filesysyem is ext2fs, parttition type 0x83

----------------------------------------------------------------------
Typing root ( followed byTAB doesn't seem to do anything...

Take a look at the grub help page. Grub

in your post it read

this addresses to swap partition, hence it cannot find the kernel.

Change it to root (hd0,6) might solve the problem...

You can manually change it from boot menu, when it appears, press 'e' to enter edit mode (or 'c' to get grub prompt),

when finish editing press Esc to back to menu and retry select the edited menu.

If succeed booting then manually edit your menu.lst.

Hey hurry_hui, thx 4 the feedback...
I still don't succeed booting; I edited the "root (hd0,5)" to "root (hd0,6)" and pressed ENTER. Now when I press 'b' to boot it seems that it might boot, but then prompts me to enter the root password. Upon entering the password it gives the "(repair filesystem)#" prompt, and I don't know how to proceed from there (sorry I'm a bit n00bish).
Another thing, do you think I should edit the other entries on the boot menu as well? For example, when enter 'e' for edit when it's the "windows" entry highlighted on the menu, I get these 2 lines:
rootnoverify (hd0,5)
chainloader (hd0,0)+1

The other 2 entries other than openSUSE (i.e. Failsafe and XEN) also have the line "root (hd0,5)",so I wonder if I have2 edit that as well to "root (hd0,6)"?
And how do I save after editing in the grub prompt?

If you use the "repair filesystem" you should not have to modify anything. You should have some options with the repair and one of them should be repair boot or grub. It has been a while but if I remember it will repair grub then let you opt out on repairing (overwriting) operating system.
