MacBook Pro won't boot to recovery or Mac OS Install disc

I just got a Macbook that needs to be reformatted for a new user. I tried rebooting into recovery with command + r and all it did was go back into the login screen. Then I tried re-installing Mac OS 10.6 with the disc and reboot while pressing c and it stopped at the grey apple screen and doesn't change. I tried restarting again with the c key press and did the same thing. I left it on overnight thinking it was just taking a while to load the cd, but no change.

Please do this:
Turn on the mac book, immediately press and hold:
CMD + ALT + P + R
The screen will go dark and the computer boots again if successful. Release the keys.
Then, turn off the MacBook and turn it back on, but holding the power button pressed for several seconds until you hear a loud beep sound. Them release the power button.

Next, turn off the MacBook and tun it back on, leaving the ALT key pressed.
You should be presented with a list of bootable devices.
Can you see and select your Recovery Partition?

There won't be a recovery partition unless the Mac had 10.7 or 10.8

Is the 10.6 you are using a full retail install DVD? If it is black, it is and should work.

If it is grey it is an OEM disk that came with a new Mac. Unless the Mac you are trying to boot was the exact same model as the one the grey OEM disk shipped with, it will not boot your Mac.

helge000, I chose the option to boot to the install cd and the screen went to the gray apple screen and hasn't changed.

strung, I bought a 10.6.3 2z691-6634-a install DVD from the Apple Store. The disc is white. Is there a Difference?

If you bought it from Apple, it should be a full retail DVD.

If you have another Mac, connect your MacBook with a FireWire cable and boot your MacBook into Target Disk Mode (press the T key while booting) this will boot your MacBook as an external hard drive.
On your other Mac you should see your MacBook as a mounted hard drive. You can run Disk Utility and repair your disk. You may want to retrieve any files from the drive as backup.

Once done, reboot your MacBook! If you still have issues, you can install the OS while in Target Disk Mode using another Mac!!

Silly question but I've got to ask. :-)

Did the Macbook in question come with 10.6.x or earlier?  If so, did it have a firmware upgrade or two?  If not, with which O/S did it come originally?

Finally, what is the exact version of 10.6 listed on the disk (10.6, 10.6.3, 10.6.4, 10.6.8, ...)?

I ask because it is possible that a sufficiently new Mac or one that has gone through firmware upgrades might not boot with a 10.6.0 disk.  However, a newer version of the disk might work.

The I don't know if it had another version of OSX on it but it was 10.6.6. I tried looking up the version of mac I have and it showed that it's Model: A1286 MacBook Pro (15-inch, Mid 2010) and its one of the following I don't know which one: 2.4GHz MacBook Pro (MC371LL/A), 2.53GHz MacBook Pro (MC372LL/A), 2.66GHz MacBook Pro (MC373LL/A). It still won't boot the 10.6.3 disc I got from apple. I'm starting to wonder if I should just send it to apple to get repaired.

Before getting it repaired, try booting from a 10.7 source.  If it boots, try running a disk repair.

Should the above options fail then I would look at the possibility of it needing repair.

Otherwise, look at trying a 10.6.8 disk, if one exists.
