Nevermind, it's already working
I tried following this guide to set up a dual boot.
I just finished defragmenting my C: drive and everything is in the front of the disk now, so i booted into the System Rescue CD (page 2 of guide) as the guide tells me.
The guide then tells me to do this (after entering 'boot: fb800 nodetect'):
After the rescue CD boots, you'll see a Linux command prompt. Enter run_qtparted to launch the QtParted disk partitioning application. (Documentation and screen shots are available from the project's site.)
Well, i tried to run it and it comes up with an error that the command doesn't exist. I think the reason is that it has been removed in the newer versions... However now i need to find a Rescue CD that still haves it or and older version of it. Or am i just doing something wrong and/or should partition in another way?
