    I just bought my friend's Macbook Pro today. Upon checking. It only boot up on Windows 7. I try to reformat it but it only redirects me to windows utility. I also try to boot up the drivers but it only has Windows C: on it. I read almost everything I can find on the internet but no luck. Any of you guys can help me out? Please help!

    If it has APS as the MacOS partition format Windows can't see it. You will have to hold down option while booting then select the MacOS partition if the Bootcamp partition is the default boot partition.

    What I'd try:

    Boot to internet recovery:
    1. Power off the MacBook, all the way off.
    2. Press the power-on button.
    3. Hold down the Command (⌘) – Option (⌥) – R combination immediately upon hearing the startup chime and KEEP HOLDING THEM DOWN
    4. You should see an icon that indicates booting to the net.

    You -may- need to enter the password for your local wifi setup.

    If it boots to internet recovery, you want to open Disk Utility.
    Now, you need to select the item that represents your internal drive (NOT a "partition on the drive", but the drive itself).

    Next, choose to erase it to "Mac OS extended with journaling enabled" (GUID partition format).
    This will NUKE THE DRIVE, back to "nothing on it".
    It's now ready for a fresh OS install, so...

    ...close Disk Utility and open the OS installer.
    See if you can install a copy of the OS onto it.
    Be aware that the installation may involve one or more reboots and it will take some time.

    IT DOESN'T MATTER WHICH VERSION OF THE OS at this point.
    All you want to do is to get SOMETHING onto the MacBook to get it booted and running the Mac OS again.

    Once the installer is done, you should be presented with a setup screen.
    Go ahead and set the thing up, see if you can get an account created and get to the finder.

    Does this work?

    What year is the MacBook Pro?

    If NOTHING works, I'd suggest this course of action:
    1. Go to ebay
    2. There are sellers there who will sell you a USB flashdrive with a copy of the Mac OS installer on it. (you need to find one who has the version of the OS you want). These sell in the $20 range.
    3. The flashdrive installer will be bootable
    4. Insert the flashdrive, press the power on button, and hold down the option key CONTINUOUSLY until the startup manager appears.
    5. Select the flashdrive installer with the pointer and hit return.
    6. The Mac should boot from the flashdrive.
    7. Don't try to install yet, open Disk Utility and ERASE the internal drive
    8. Once erased, now open the installer and install the OS.
