What is the safest way to triple boot Macbook Pro?
Solution 1:
Lifehacker's guide to triple booting has worked well for me in the past. You will also definitely need refit. I've seen varying reports of how well refit works on Lion - it seems to be that if you don't have FileVault enabled, you should be fine. Obviously make sure to back everything up before starting - any sort of partitioning/boot loader editing/etc is always slightly risky.
The basic steps are:
- Install refit
- Partition all the necessary partitions (OS X, Windows, Linux). Be careful at this step, it can be very difficult to resize partitions that aren't HFS+. You'll need three additional partitions: Windows, Linux, and Linux swap.
- Install Windows, then install uBuntu.
(Lastly, this does not invalidate the MBP's warrantee.)
