[kamranhameed]

folks i have installed 3 OS on my machine giving me tri boot option..

2. SLES (SuSE Linux Enterprize Server )
3.opneSUSE

Now i want to deinstall SLES, so that i should give me a dual boot asking for openSUSE and Windows.If i deinstall SLES, that will remove the Grub as well.. Can any one tell how to do that?? plz tell me comprehensively coz i will not be prehaps backing up my data...

Regards!

one thing i forgot to mention is that "Is it possible to allocate the space of SLES to openSUSE?? if yes then how?


Regards!

Which Distro's GRUB are you using right now?
Its very easy to remove any OS and allocate its space to other OS.
Boot up OpenSuSe, log in as root and execute this

fdisk -l

Post output here. Post the contents of /etc/fstab file too.

i am using open Suse

Here is the output of fdisk -l

Which partition has OpenSuSe? /dev/sda7 or /dev/sda8?

[kamranhameed]

open suse is on /dev/sda8

i want to remove SLES which is on /dev/sda7

[devils casper]

Ok ! You have to edit /etc/fstab and /boot/grub/menu.lst files.

Boot up OpenSuSe and post the contents of /boot/grub/menu.lst file.

Download PartedMagic LiveCD. You will need it to merge partitions.

i got the PartedMagic Live CD.. and here is my menu,lst file of openSUSE

Back up data before changing partition structure.

Edit /etc/fstab. Replace these lines:

/dev/disk/by-id/scsi-SATA_FUJITSU_MHV2100NW9YT6A2EHKP-part8 /                    ext3       acl,user_xattr        1 1
/dev/disk/by-id/scsi-SATA_FUJITSU_MHV2100NW9YT6A2EHKP-part9 swap                 swap       defaults              0 0

with these

/dev/sda7 /                    ext3       acl,user_xattr        1 1
/dev/sda8 swap                 swap       defaults              0 0

Edit menu.lst :

gfxmenu (hd0,6)/boot/message
 
###Don't change this comment - YaST2 identifier: Original name: linux###
title openSUSE 10.3
    root (hd0,6)
    kernel /boot/vmlinuz-2.6.22.5-31-default root=/dev/sda7 vga=0x314 resume=/dev/sda8 splash=silent showopts
    initrd /boot/initrd-2.6.22.5-31-default

Does Windows OS boot up fine?
This is incorrect code for Windows OS in menu.lst file.

Anyways, edit both files and boot up from PartedMagic LiveCD. Delete /dev/sda7 partition and merge space in /dev/sda8. /dev/sda8 and 9 will become /dev/sda7 and 8 respectively. Reboot machine.
