Refresh install of ubuntu in dual boot system

[Leion]

Hi,

Currently have installed Win XP and ubuntu 8.04 in my laptop.
Grub is the boot loader.

I would like to reinstall my ubuntu only and resize my partitions for it. How can I do so without reinstalling my winXP ?

Hi Leion,
I have done this same process before. Just boot off of your Ubuntu install disc and start the install process again. When you get to the Partitioning part, just watch carefully which option you choose. Its been a while, but I believe the option was to use the existing Ubuntu partitions.
