Some things on the last few posts to note about.
A CD key that came with a computer will NOT work on any CD you get and try to install. You need a CD key from a past copy of Windows, or just a new key. Retail and even OEM CDs will not accept the volume OEM licensing versions which your PC manufacturer gets from Microsoft.
A lot of games do now run on linux, just that most of the ones I seemed to get ran on kernel 2.4.

Wasn't really too bad, just keep a small partition of Redhat 6.1, fire it up, and play them. Of course, if I felt the need, I could play them in Windows, but, well, I don't know, lol.
Vista. Well, Vista, unfortunately, installs itself, and completely ignores the use of the same bootmanager we've known forever. This also takes away the use of the boot.ini file. There is no where to edit the boot loader to chain boot either. On my last attempt to dual boot the two, I resulted in an error after GRUB loaded, and I selected the Windows partition. It was just hd(0,0), followed by a bunch of nonsensical symbols.
The best way I see to dual boot the two, until (to my knowledge it does not yet exist), a new bootloader comes out, is to install your operating systems on two physical disks, with two separate MBRs. Then unfortunately, from here, you'll probably have to toggle the two seperately via the BIOS, unless you have any special hotkeys enabled for this at boot time.
