Uninstall Windows XP
 

Hi, I am currently using windows xp and ubuntu. Now i just want to use ubuntu, how can i remove windows xp and release all space to ubuntu?

Ubuntu has GUI tools like GParted for this.
In fdisk you just delete both partitions and (re)create the one from Ubuntu(usually /home) to use all space.

Post the output from "fdisk /dev/hda" (or whatever) if you need more specified info.

Oh, thx, will grub update if i use gparted to remove windows xp?

This depends on where your boot files are installed.
Posting your partition table would be very helpful.

Even if it doesn't boot you can simply reinstall grub using any cd/dvd/... that has grub.

oic. how can i reinstall my grub if my grub is corrupted?

Assuming you only have one hard drive (using your installation/live cd):
grub-install /dev/hda (for IDE)
grub-install /dev/sda (for SATA)

oic, thx for ur help.
