Remove Ubuntu and partition?

I installed Ubuntu today, and I don't really like it. I was thinking of trying Mandriva, or Slax. Maybe even Puppy Linux. The only problem is it's a little to slow. I was looking for something faster. So how do I get rid of the partition? When I click the Windows XP option from the Dual Boot screen, it just hangs there. So it won't boot.

When I open Gparted, theres a pair of keys next to this: /dev/sda2
I can't edit it, or do anything to it. Theres also two other things under the /dev/sda2 (still trying to figure out what they are).

Since I can't delete the partitions in Ubuntu, and Windows isn't booting I can't delete it to try another distro.

Any help? I was also going to increase the size of the drive, so thats why I wanted to delete it. Otherwise I would just install over it.

Thanks, all help is appreciated.

 

OK.. xp isn't booting because the boot/grub/menu.lst file isn't properly pointing at windows.

Yours should have an entry like this at the bottom

Code:

title Microsoft Windows XP Professional
root (hd0,0)
savedefault
makeactive
chainloader +1

boot ubuntu and post your boot/grub/menu.lst file and we will sort it out XD

 

Well I'm going Puppy Linux, I got Ubuntu removed with a Gparted live disk (had to reformat windows though, no biggie).

 

I don't understand what you don't grasp about using the linux tools... when you boot linux you can chose a runlevel from the prompt..

With ubuntu you have to hit <esc> while the splash screen is up to get the grub boot menu, then select the single user mode.

Login as root and use umount to unmount the filesystem you want to kill.. then use cfdisk to resize/reformat/delete/make partitions.

Puppy has gparted included so that's fun. The reason for the keys on the partitions earlier is because they were mounted, and you can't unmount them with a partitioning gui application running within an operating system which is running from the mounted partitions.
