problem in GRUB OR MBR

[kamranhameed]

folks i installed open suse 11.0. Every thing was working fine.. Then i committed a very ******** mistake. I tried to allocate some space from my window Partition on linux partition. using YAST.

Now what happens is, when i boot, Nothing is shown.. no menu.. just black screen.. probably some problem with MBR. I tried to boot with CD in the rescue mode, but in the end, it says "MBR corrupted".

Interestingly enough, i went on to make a new installation, and instead of choosing "new install", i checked "Upgrade" and guess what? When i booted, my all previous settings+data was there...

But the worst thing is, that even after doing it, when i rebooted, again, nothing is shown, except the black screen.... so now when i have to use PC,.... i boot with CDROM and upgrade it, use it then do this process again and again....


Can any one tell?

Try to re-install grub. Open Terminal and execute this

su -
grub

You will get a grub prompt, grub>
Execute this:

find /boot/grub/stage1

If you get "Error 15: File not found", try the following:

find /grub/stage1

Using this information, set the root device (fill in X,Y with whatever the find command returned):

root (hdX,Y)
setup (hd0)
quit

Reboot machine.
