Re: @David Hagood
Macs have proven far more difficult to multi-partition than any Windows machine, in my experience. Windows machines these days are a doddle to me compared to something running OSX. First you have to resize the partitions using an editor that takes your inputs as mere suggestions. Then you have to deal with their non-standard bootloader (constantly), plus the hybrid partition table that becomes irritatingly necessary despite the other two operating systems both supporting EFI, and then because of the hybrid table, you have to have your partitions in the right order or Windows is screwed. Get all that set up and make sure you remember to sync the partition tables, otherwise OSX will merrily destroy your other partitions without prompting you. Gah!
Getting 3 operating systems on this 2011 MacBook Pro was....not fun. Not looking forward to a ML upgrade. Wouldn't be so bad, except my old 2007 MacBook was much easier!
