I have a Macbook Pro 8,2 and I managed to install Windows 8 and Ubuntu 12.10 along with Mac OS X Mountain Lion.
To make my life ‘easier’ I decided to install rEFIt, which did not work correctly and did not display all my operative systems, so I uninstalled it by erasing the folder “/efi/refit” using OS X.
Then I stumbled upon rEFInd, which seemed to be a better option as it had been updated as compared to rEFIt which development seem to have stopped in 2010.
Now, rEFInd ‘worked’ in the following manner:
It’s menu showed the following:
From left to right.:
Option 1.- Mac OS X
Option 2.- vmlinuz-3.5.0-22-generic
Option 3.- initrd.img-3.5.0-22-generic
Option 4.- vmlinuz-3.5.0-17-generic
Option 5.- initrd.img-3.5.0-17-generic
Option 6.- Linux (Ubuntu)
Option 7.- Windows 8
Options 2 – 5: took me to some kind of ‘Terminal’
Options 6 & 7: took me to Ubuntu’s booting menu. (Where I could choose from Ubuntu and Windows 8)
Now, this made having rEFInd useless for my purposes. So I tried the following to remove it.
Attempt #1 - Followed ‘Uninstalling rEFInd’ (http://www.rodsbooks.com/refind/installing.html)
I followed the procedure for OS X, which consisted of opening the terminal and doing:
$ sudo rm -r /EFI/refind – Result: No such directory was found.
I later tried on Ubuntu’s Terminal:
# rm -r /boot/efi/EFI/refind – Result: No such directory was found.
Attempt #2 – Tried Following THIS: https://bbs.archlinux.org/viewtopic.php?id=152832
Upon trying to do ‘# efibootmgr -v’ I got the following message:
Fatal: Couldn't open either sysfs or procfs directories for accessing EFI variables.
Try 'modprobe efivars' as root.
Then ran 'modprobe efivars' in the terminal, but it made no difference.
Attempt #3 – Ubuntu’s Boot-Repair
Installed and used the automated ‘Recommended Repair’option.
Added an 8th option on rEFInd, option 1 is the only one that boots, booting OS X, the rest of the options are un-operational/don’t boot an OS.
NOTE: Boot-Repair created this report: http://paste.ubuntu.com/1589208/
Partition Inspector on Mac OSX shows the following: http://pastebin.com/sXg6wjxE
rEFInd initiates upon booting, only Option 1 (OS X) works.
I need some guidance/help on:
-Fixing my booting options.
If I can’t solve it then I would like to know how to reset my Macbook 8,2 to manufacturing settings. (The recovery option does not appear when I press ‘Alt’ upon turning my laptop on)
Any help would be GREATLY appreciated.
