Upgrade dual booted MacBook Pro to Lion from Snow Leopard/Ubuntu I have a MacBook Pro running Snow Leopard and Ubuntu on separate partitions. I use rEfit to choose which operating system I want to boot into. I would like to upgrade to Lion, but I'm concerned this will cause major problems due to my partitioning scheme. Has anyone else done this?
I used to dual boot fedora and snow leopard on a macbook pro and upgraded it to Lion no problems. You should just be able to upgrade as normal without altering your ubuntu partition, although as per Vlads answer it's always best to take a full backup first (not that I'm always very good at following that advice myself).
