Quad Booting (XP, Vista, Linux, Mac OS X): Complete How To
This guide is a comprehensive guide for quad booting on a single hard drive with wireless internet access on all platforms and introducing basic networking on all platforms to access network shares on other computers. It took me a bit of time to figure out so I decided to write a guide for others who were interested in going this route.
This guide is based on specific hardware and it is uncertain if the procedure will work on other hardware. If you are going to attempt quad boot I would strongly recommend installing the operating systems separately first, so you make sure they all work by themselves. Also, it is very helpful to have a usb flash drive handy and a separate computer running windows so you can download stuff as needed and put it on the flash drive. That being said, lets continue.
