So I have this one single pc right now floating around here that doesn't have a cdrom drive. Hooking up a cdrom drive is an extreme hassle as the case only has room for a slim drive and I haven't gotten one for it. To make it more fun and exciting the machine won't boot off a usb flash drive or usb hard drive go figure. Either way that leaves me with a couple of choices on being able to perform an operating system installation. The first is to go out and purchase an external cdrom drive and just do it which is kind of lame and not very interesting.
