I am just about to install Yellow Dog Linux 6.1 on my spare HDD and I would like to know if I have to do some configuring to be able to dual boot. My first idea would be if I hold down option on boot and I am presented with the usual HDD boot options. Will this work? I also thought of another idea - that a boot loader would be needed, although I have no experience with boot loaders (or even what they are really). To summarize - I have Mac OS X 10.4.11 install on a 128GB HDD, and I am about to install YDL 6.1 on another 50GB HDD, and I would like to know how to go about dual booting. Thanks so much!
