tip: what to do when grub crashes
 

just to share with whoever needs this tip

i somehow screwed up my grub loader. and my system now boots to the grub shell if i may call it so. so here is what you do, assuming that your menu.lst still intact

grub> root (hd0,#)

# refers to partition number where your system is installed

grub> configfile /boot/grub/menu.lst


and it should boot fine .... i am using kubuntu

good luck

Say My Friend informs me that a system has been screwed up and now it displays only
And Yu say
How Gonna I know Which partition the system was installed.Thats Not my System.Then Its Obvious I am not familiar with the system before.
How gonna I track it out?

you can try out a couple of them ... and check if filesystem is there

But How? Thats my question?

grub has the feature of command completion when you hit TAB

start to write and hit TAB at any place for a display of anything that fits what you have written so far...
For fun: try to boot your perfectly working system this way and you will see (hit "c" or "e" when the grub-screen shows up)

You can also use the find command at the grub prompt:

find /boot/grub/stage1

This will give you the partitions with grub but it isn't always helpful if you have multiple operating systems.

I managed to bork my grub last night with two phantom OSes in the MBR, and I did what I always do: loaded the "Super Grub Disk". Yeah, it's nice to know the grub commands, but I can never remember them all when I need them the most. Super Grub Disk is just the easiest solution for me.

Standard Disclaimer: I have nothing to do with the SGD software.
