I'm booting Ubuntu from rEFInd on a 15" MacBook Pro. For a long time I haven't had a problem, but just now booting has been hanging on the error
Invalid ROM Contents
This seems to happen when it attempts to mount /dev/sda3
which is the Ubuntu partition. I've read that this may be related to graphics and I can boot an older version of the Kernel without graphics, however nothing else that I have read has helped and I am at a loss as to what to do. Any suggestions for fixing this error?
Reinstalling the nvidia drivers seems to have fixed the problem. Boot headless (you can probably use one of the backup kernels).
