GRUB issue
 
Hi,
After installing Ubuntu 8.10 in my laptop I-ve partitioned the disk and I-ve installed win xp in another partition. Since this GRUB doesn-t appears when my laptop boots and I can only use xp. How to solve this?

xp overwrote the bootloader links in the mbr.

get a live cd and just re-link the mbr to your /boot partition

eg if /boot is on partition 5

Code:
su
grub
root (hd0,4)
setup (hd0)
quit
while in live mode...mount the harddrive partition and edit grub's /boot/grub/menu.lst to have a chainloader menu

my signature may help?

if you do not know how to use a live cd...too well..after doing just the grub...reboot to hard drive...boot into linux and then edit that file with root powers..the file /boot/grub/menu.lst

sudo grub
find /boot/grub/menu.lst (use the output in the next step)
root (hdx,y)
setup (hd0)
quit

To use "su" in ubuntu you must use,

sudo su

To make sure XP does not override GRUB again, always install Windows first, then Ubuntu. As a warning, I have not figured out how to change the default OS from Ubuntu to another OS.
