In that case the only thing to do is:
remove rEFItBlesser in /libary/Startup Items/
Restart computer or shut down and open
Open Terminal
type:
cd /efi/refit
./enable.sh
fill in your (computer login) password....
exit
And it works.
I did not test this without the repairing disk and disk permissions with a install CD. I am so glad it works now finally.

Hey guys, just wanted to confirm that this is working for me so far on late 2011 17" MBP running OS 10.7.5.
