I have used 10.04 for a while using the wubi installation with Windows XP.
I then uninstalled it and gave Fedora 13 a try (on its own partitions).
Now I would like to completely get rid of Fedora and install ubuntu 10.10 (not using the wubi, but the real thing this time), so I will have a dual boot with my XP.
What's the best way to do that?
The only caveat is that I don't have the XP CD in hand (I know it's needed sometimes to run fixmbr
from recovery console to get rid of grub). I can ask for the CD from our admin but it would take a couple of days.
You can install Ubuntu into the partition that is currently fedora either with a CD, or with a usb stick. You can download the necessary iso from http://www.ubuntu.com/desktop/get-ubuntu/download. The Ubuntu help wiki has more information how to install dual-boot
To fix the MBR you can use utilities independent from the XP CD http://www.ultimatebootcd.com/ is just one of the examples.
