I have my friend comp and convinced him to try Ubuntu instead of Windows. He doesn't know much about comps so I'm dealing with all the starter things he'd need. He presantly has Windows XP installed and for the life of me I can't remember, or never knew how to uninstall it.Windows sucks!! I can't even find a web site of there's that explains how to do it, so if any one remembers how it's done please send me a message back.

Just boot from a Ubuntu CD.You'll have an option there to delete or format XP partition.

you don't uninstall windows, you just install over the top of it.

You just need to boot the pc from the ubuntu cd and then remove/format the windows partition. First go through the install instructions at the ubuntu website.

You may want to save any important data first, unless you don't care, in that case follow the others advice.

Duplicate post, see below.

I would definitely recommend to either make sure that you friend has at hand a trusted media with which he/she could reinstall Windows if he/she ever wants to, or even better do not erase Windows but configure a "dual boot" Windows / Linux on his/her computer.

To do that:

1) Get gparted. For that I recommend dowloading and burning a live cd
2) After having made a backup of all valuable data, use gparted to downsize the Windows partition(s), in such way that you keep only around 10 free gigabytes inside that partition.
3) Then with gparted reuse the freed disk space to make three Linux partitions:
- the first of around 20 gigabytes for /, formatted as Linux, e.g. ext3 filesystem
- the second of the RAM size for swap, formatted as Linux Swap filesystem
- the third using the remaining disk space for /home formatted as Linux, e.g. ext3 filesystem

Be careful while using gparted : do not interrupt it while it is running, knowing that some operations -- noticeably resizing -- can take a lot of time.

After that you will be able to install any recent distribution, instructing the installer to configure a dual-boot Windows / Linux, using the already prepared partitions as stated above for Linux.
