If your MBP came with lion or mountain lion. You will need to reboot the computer with a bootable Lion DVD. Unlike previous versions of Mac OS X, Lion (OS X 10.7) doesn’t ship with a bootable disc—it’s available only as an installer app downloadable from the Mac App Store. Once you have attained one of these disks. Boot and enter utilities and reformat the hard disk. Ensure that "Guid" is selected under options and that you also select "Mac OS Extended - Journaled. Hopefully before you do any of this you have a very recent time machine backup.
Once reformatted the computer should startup from the Lion Boot DVD without the beeps and you can reinstall the OS and restore your backup.
