Sorry, I don't use windoze, so I'm no help there. Is windoze already
installed?

As for ubuntu, why do you want to install an outdated version? Support
for 8.10 ends in a few weeks, and almost nobody is still running it, so
it will be hard to get help. I recommend you go with the current version
of ubuntu, 10.04, which will be supported for 3 years. (the server
version will be supported for 5 years).
