Lion uses the + R to boot into recovery mode. Resetting the PRAM in anything less than 10.7 was + + P + R.

Recovery mode now seems to override the PRAM command. Does anyone know if there is a new way to reset the PRAM now that Lion is installed?

It's a matter of timing. You need to push these key immediately after turning on. If you wait too long, the bootloader is already active, which uses Cmd+R for the recovery function. – René Aug 9 '11 at 7:18

Resetting the PRAM works the same way it always did. This is a function of the hardware - not the OS. What makes you think it doesn't work anymore? (tested on Macbook, Mac Mini).

I tried it 4 times on my wife's MacBook and it booted into recovery mode each time. – Nate Bird Aug 9 '11 at 14:35

Nate , PRAM reset is not working because you turn on Password Firmware Protection. Turn it off and P+R+Option+Command will work.

Had the same problem, and this was the solution – René Aug 3 '12 at 13:52

Or she has spilt something on the keyboard and the shift key is telling the computer it's being held down, so no matter what, it will boot into recovery mode. I work for an apple specialist and see it all the time.
