Can't re-install Mountain Lion

Hey everyone,


So after my girlfriends HDD in her Macbook Pro 9,2 died, I changed it with another HDD and I can now create the partitions etc that I need to reinstall Mountain Lion.

I try to use the Internet Recovery method where it downloads and install automatically. My problem starts when it says that it is installing and the progression bar is moving. It started at 40 minutes, and every time it hit 0, it simply moved back to 40 again. After I had seen it do that for a couple of hours I went to bed. When I got up this morning, a pop-up on the screen said that it could not get the components needed for the installation (or something quite similar to that).

My internet connection is a 30/30 so I don't think that would be the bottleneck.


Does anyone have an idea of how I can make it work again? All ideas are welcome 🙂

If you have access to another Mac computer and she has purchased Mountain Lion before, go to the App Store and sign in with her Apple ID. Go to the Purchases tab and download, then quit the Mountain Lion installer. You can make a bootable USB stick to install using this free program which will do all the work for you. Boot off the USB drive and install the OS.
