I was under the assumption that you tried linux and already had it installed, however, if you have the image file or the live install cd and a 1 GB flash drive, you can boot linux from that. Otherwise you can get ubuntu here
. You can burn it to cd or dvd or use uNetbootin
to make a bootable flash drive. Once you've got the ubuntu desktop up, you'll find gparted by clicking on the system dropdown menu and selecting administration (upper left). Gparted has the ability to move partitions into free space too, but moving a large partition can take hours, so I would only do it once, when you've freed enough space on your system partition to shrink it to 60 gb, then move your media partition to the left and expand it to fill the rest of the free space. Since you're planning to reinstall windows anyway, you won't have to worry about damaging system files. You can create free space in your hdd by deleting the windows folder and the program files folders, and Gparted will compact everything into the gaps created when you shrink the partition. You'll have manually empty the trash after deleting anything in order to create free space. (lower right corner of the ubuntu desktop).. (or you can simply format the partition after you have everything you need, and resize it to whatever you want)...The interface is pretty easy to use, just be sure to format any new partitions you make to NTFS. (Default is ext file system used by linux, which can't be read by windows) Another thing, move your personal files and media out of the users folder (My documents, My music, etc) if your account is password protected before going into linux or you might not be able to find them. Good luck and if you have any questions, please ask before doing something when you don't know for sure what's going to happen... wish my customers would listen to me when I say that..
