I recently purchased a MBP 13.3 i5 system, and I'm keen on making it triple boot (Lion, Win7, Ubuntu 11.04). What is the safest way to do this ? I found quite a few websites online, but I'm not sure of whether they are entirely accurate/updated for Lion etc.
I would really appreciate it if someone could post a link that has worked for Lion/Win7/Ubuntu 11.04.
Also, would this action invalidate the warranty of the MBP ?
