Getting boot done error on 10.8.2 Niresh AMD #iATKOS #ML2

Ok im using a amd processor and a 7970 gpu so when the installation is done i get a error telling me to change the startup disk, and i restart then i get this:

boot0: GPT

boot0: test

boot0: test

boot0: Done



When i use a old gt520 it boots but i get a kernel panic. but when i use the 7970 i get the error and it stays at that.:(
