Hey all!

I have had this problem since i first got my Mac Book Pro (7,1) a few years back. I've tried every Ubuntu version from 8.04 to 12.10 without any luck....

It boils down to Nvidia MCP89 and linux not being able to recognize my hd. I'm running Mac OS and Win 7 with no problems at all. I use rEFIt as boot manager.

One recent errormsg when I boot:

init: line 7 can't open dev/sda/

I've tried following this guide to install grub2-efi to see if that helped, but as I can't boot from anything writable like a flash drive or external hd I'm helpless.

Can anyone please guide me in the right direction?
