I'm trying to install elementaryOS (which is based on Ubuntu 10.10) on my MacBook Pro 13" Early 2011 (model No 8,1). I have resized a partition on my hard drive, and I've installed refit. Two things I've noticed:
refit doesn't notice the optical Drive, however pressing c allows me to boot the CD.
When I try to install or "try" the OS, I always end up with the following message:
(initramfs) unable to find a medium containing a live filesystem
I think these two things are connected - perhaps the OS isn't giving access to the optical drive somehow?
