Hi, I want to set-up a dual boot system with Windows 7, my laptop's original OS, and Mac OS X. As I said in the title if at all possible I would like to do a triple boot with Windows, Mac, and Ubuntu. I've been doing research, and I've found that, correct me if I'm wrong, I need a partition on my disk for each different OS. However, because my C drive is a basic disk, and HP have filled up the maximum of 4 partitions with, 'system', 'C', 'HP_Tools' and 'Recovery'. I don't want to delete any of these, as from what I've read they could stop me being able to restore Windows if something were to go wrong with it. As a result of this my only choice is to change the disk type to dynamic, as I can create more partitions. But I've heard that I am unable to install OS's on this type of disk. I've already tried both in Virtualbox, but I actually want them as a booting OS rather than in a sandbox. Also, are there programs that enable the dual or triple boot up thing, such as Chameleon which I've heard of but not sure about. Thanks.
