You will need to take it to an Apple repair center where you will be asked for proof of ownership, then they will remove that EFI password for you. You can read about it here.

Replacing the hard drive will not get around this.

Ask your friend for the password. There is no way to circumvent or change the password, other than taking it to Apple.

That means the system cannot find the OS to boot from. Most commonly this is a bad drive.
when is drive bad and i am trying to get to recovery would show that greylock?

You need the firmware password to boot from a different volume, so yes, you'd get the password prompt when trying to boot into recovery. You'll need to get the password from your friend.

You have two things going on at once here. When that EFI password is turned on (the one that is giving you the grey login screen like below), it locks the machine to whatever boot drive is currently selected. That why when you try to command-r boot you are getting the EFI PW prompt.

The second issue is you likely have a bad hard drive there and that is why the system won't boot and gives you that question mark.

Like I mentioned... take it to an Apple repair center and prove you own it and they will fix you up.

Seems to be a lot of dancing around here with no one suggesting the obvious...

But it ain't going to be me! :p
I'm inclined to agree, although it's never known for certain. I find it interesting that someone who I assume used the computer on at least a fairly regular basis wouldn't know the firmware password required to boot up. Granted, that's an assumption and there are many possible scenarios, but on the surface, it "smells funny".

Thing is the firmware password is not required for normal boot up. If you set an EFI password then use the machine with the same drive, you would never need to enter the EFI password again. I typically set an EFI password when I buy a Mac, then never enter it again until I go to sell it.

Interesting! And all the more reason to make sure you never forget the password, if you set one!

Who bought it from Apple? Apple knows who bought it originally. Unless this computer came from a "friend" who got it from a "friend" who got it from a "friend's" trunk in a dark alley. He should be able to help you out.
