Hey poliva, I booted into the Ubuntu live USB and ran the command for all of the sda* shown: both sda and sda1 returned "GRUB" output. There is also a grub folder in /boot/ for that partition (i.e. /boot/grub/). Does that mean anything to you?
Code:
$ sudo strings /dev/sda |head -n 30 |grep -i grub
GRUB
$ sudo strings /dev/sda1 |head -n 30 |grep -i grub
$ sudo strings /dev/sda2 |head -n 30 |grep -i grub
$ sudo strings /dev/sda3 |head -n 30 |grep -i grub
$ sudo strings /dev/sda4 |head -n 30 |grep -i grub
GRUB
$ sudo strings /dev/sda5 |head -n 30 |grep -i grub

Ok, I removed rEFIt and installed rEFInd, following the instructions to manually install it using Mac OS X and installing it to the /Volumes/esp/ partition (disk0s3 for me).
Now when I reboot, rEFInd is showing only the Mac icon and no other icons. The MBR is exactly the same as before. What can I do for next steps to troubleshoot this?
