Help restoring Grub.

Ok Installed Mandriva 08 .. It took away my Ubuntu Grub .. Well now Mandriva even not working

It nly works just after I install it and after 2 bot I end up in GDM hangs.

Sucks.. Well thats not the point how can I restore my past fiesty grub so that I can use till my Cd arrives..

You should have known that, or should have searched it at least, being so good at Linux here. There've been so many threads on this ...

Anyway, the procedure is:

Easy and Dumb:

1. Boot your computer up with Ubuntu CD
2. Go through all the process until you reach "[!!!] Disk Partition"
3. Select Manual Partition
4. Mount your appropriate Linux partitions

/
/boot
swap
.....

5. DO NOT FORMAT THEM.
6. Finish the manual partition
7. Say "Yes" when it asks you to save the changes
8. It will give you errors saying that "the system couldn't install ....." after that
9. Ignore them, keep select "continue" until you get back to the Ubuntu installation menu
10. Jump to "Install Grub ...."
11. Once it is finished, just restart your computer

Smart:

1. Pop in the Live CD, boot from it until you reach the desktop.
2. Open a terminal window or switch to a tty.
3. Type "grub"
4. Type "root (hd0,6)", or whatever your harddisk + boot partition numbers are (my /boot is at /dev/sda7, which translates to hd0,6 for grub).
5. Type "setup (hd0)", ot whatever your harddisk nr is.
6. Quit grub by typing "quit".
7. Reboot.

^^ My bad

But still help is always appreciated and now I'll not forget it

Just be careful if you got multiple hard-drives

always bakup ur old menu.lst file.

Shashwat, I think you had the same problem a few months ago rite? At least you should've been more careful this time.

Were you able to solve this problem?

Ya did solved

and I had same prob months ago

Well how to merge 2 grub menus.. I mean when open SUSe mandriva sk me to install grub should I install it in the same HDD of Ubuntu 1

You're installing it onto the MBR right? If so yeah, you have to let it overwrite and hope that it detects the Ubuntu too.

Else, after you get inside SUSE/Mandriva/Whatever open the Ubuntu partition and see the menu.lst there and paste the required entries to the acting distro's Grub's menu.lst as required.

The best thing would be NOT to let mandriva install GRUB onto MBR. Instead let it reside on the boot partition. Then you can manually edit the grub menu list in you ubuntu and add the mandriva entry.

^^ Another option wd be not to install Mandriva's GRUB at all..
So that u dont have to pass thru two bootloaders to get to Mandriva...
Or keep the Mandriva bootloaders default OS as Mandriva and keep the waiting time 0 secs..

^^^ I think I said the same thing about not installing Mandriva Grub!
