I have seen someone using XOSL to do multi-boot. Actually, this is my first time messing up with multiple OS. Do you guys have any tutorials or guides for me to learn?
Assuming that I am using a brand new hard disk, what should I do first? If I have installed two or more OSs on the hard disk, how do I share files between these OSs?
A little bit off-topic: if my BIOS supports booting from a thumb drive, can it support booting from an external hard disk as well?
