Problems booting into USB OSX Installer on rMBP

[gametime10]

Here's my problem:

I've downloaded a copy of OSX Mountain Lion from the App Store on my MBA and created a USB Installer.

I've upgraded the SSD on my rMBP. It currently has one with no OS on it.

When I try to boot up w/ the USB installer to install Mac OSX on the rMBP, instead of going to the Apple symbol, it displays a circle w/ a line through it. I'm able to boot into the USB installer just fine on my MBA. Is the reason for this because I need to download Mountain Lion OSX from the rMBP, so that the right drivers, etc.. for the rMBP are also downloaded with that installation?

Any insight would be appreciated.

Unplug the USB drive, plug your rMBP into an ethernet cable(or use WiFi if you must) and hold down command+R when you boot the computer.

When you download OSX from the App store, all of the needed drivers are included. They aren't machine specific.

Command-R is not working for some reason either (I haven't tried plugging into an ethernet cable). It shows the Apple logo, but then the screen blacks out and there's nothing.

I tried downloading Mountain Lion from the App Store using the original SSD and I get this message: "We could not complete your purchase. OS X Mountain Lion is not compatible with this computer." How can this be?

I found my answer here:

Your computer shipped with a special build that is currently not available from the Mac app store to reinstall OS X. That's why you're getting that error. Apple is aware of the issue & working on an update. You will not be able to reinstall until this update is released. You can call AppleCare...they are aware of the issue & may replace your computer.

That's a bummer. If I can't get Command-R to work, not sure how I'll use the larger SSD.
