Hold the "Option" key down while you turn the computer on, and hold "Option" until you see the different drives available to boot from. Insert the OS X disk and select it from the menu.

I am considering ditching OS X too as I am not a strong mac user, but does a new rMBP come with a OS disk, or can a USB be made so I can restore the machine to OSX later if I choose to retain a bootcamp style setup?

New MBPs have a recovery partition that will allow you to re-install the entire OS without needing any disk or USB drive, even if you delete the OS X partition. I believe that if you delete the recovery partition somehow, you can still boot into the install environment and have the computer download the OS through the Internet.

Put the disk aside for a moment. Boot up the machine while holding down the Option key... what do you see?

I'm guessing OSX is still there but the previous user has set your mac to always start into Windows

in the bootcamp icon in the bottom right near the clock, right click. Then hit "boot into osx."

This is an easy fix, if you have an osx DVD/USB, and you can keep windows.

1. open "computer management" in windows
2. hit "disk management" (I recommend that you make a screenshot of this screen and post it here just in case so we can make sure that you really did lose your OSX partition)
3. click C and right click
4. hit "shrink volume"
5. shrink it by however much you want (this will be your new osx partition) and then right click that new unassigned space and format it as NTFS
6. restart with OSX inserted (USB or DVD) and hold alt
7. click OSX
8. install OSX to the new partition that you just created (not windows)

If you don't have an OSX dvd or USB, you can wipe the whole drive and start over with OSX using the online install thing built into the computer.

Still just three bleeps :/ and white screen
Hold Option again to get into the startup manager, then hold Command and V when selecting the DVD. Keep holding until you get some text. Once it crashes, take a photo of the messages and attach to this thread.

3 beeps during booting the install disk means the macbook cannot run the snow leopard version on the disk. What year model is the Macbook?

That was my first thought but the OP says that it's the disk that came with the MacBook so that shouldn't be the problem.
