> I use Windows XP, but I want Debian on my computer too. > Is that possible? Yes. You will need to either partition your hard disk or use two different hard disks. Then just be sure to tell the Windows installer to install to use one disk or partition, and the Debian (or Red Hat or whatever) installer to use the other. If you are not experienced in these things, best to get an experienced friend to hold your hand, if at all possible. Good luck!
