MacBook Pro 5,1 and Oneiric installation

[kevpatts]

Okay everyone, I know this has been covered on many threads, but after trying everything I can find (and works for other people) I still can't get Linux to boot.

I have:

• Installed rEFIt (latest version)
• Shrank my Mac partition by 28Gb using Disk Utility
• Booted from the Ubuntu LiveCD (using "acpi=off")
• Installed Ubuntu normally but with grub2 installed to /dev/sda4 (root linux partition)
• Manually forced a grub2 reinstall (using chroot & apt-get)
• Tried installing grub1 instead to /dev/sda4
• Fixed my EFI/GPT partition tables many times (http://ubuntuforums.org/showpost.php...&postcount=185)
• Tried installing grub to /dev/sda instead of /dev/sda4

I always end up with the same result:

• gptsync and rEFIt both say the tables are synchronised
• If I used grub then I get a black screen with "GRUB" in the top left corner
• If I used grub1 then I get a black screen with a blinking cursor

Any help appreciated.

HA! Got it!

Strangely enough, the way to get Grub to work properly was to chroot to the hard drive from the LiveCD and run:

grub-install /dev/sda
apt-get remove --purge grub

Amazingly this made grub1 display perfectly!

Hope this helps others.
