Re-installing Xubuntu in Dual Boot

[pavan115]

Hello, I am very very new to linux. I have been playing with Xubuntu dual booted with XP for a while. When I change the screen resolution in Xubuntu it always crashes and I need to shut down and restart it :( But anyway, I want to reinstall Xubuntu and remove all instances of my old Xubuntu. I dont have much HD to spare :| How do I do this?

Also, GRUB shows two copies of the same thing (generic, recovery mode and so on..). Will this be fixed with a fresh install?

If you need to reinstall, just install over top of the existing installation as the partitions get reformatted. The double entries in grub are just to different kernel versions.

You will be starting from scratch with a new installation.

It still has not resolved my graphics problem. I have no data in Xubuntu that I am worried about, so I want to do a new installation replacing my Xubuntu. I have the live CD with me. How do I simply erase this xubuntu and reinstall it with default settings and everything on the same partition?
