I'm not sure what all I am doing incorrectly, let me first off say that I am not experience what so ever with this sort of thing. I am looking to be able to have a dual boot machine, i have currently windows installed and am wanting to install Mountain Lion onto my system also. I downloaded the .raw file for Mountain Lion and used SUSE Studio Image Writer to put it onto a 8 GB USB stick, and then booted from the usb stick. I was then put back into windows (I am assuming that nothing happened with it, so it went to the next device down the list to boot from). Now i have no idea why it did nothing is my problem. I could be stupid and missed out on some of the instructions, or perhaps something isn't listed in the instructions that I need to do. I didnt mess with anything the the BIOS because the instructions said nothing about that, so maybe I need to do that. Anyways my specs for my computer happen to be the following. CPU: i7 3770k , GPU: PNY GTX 660 Ti , MOBO: Gigabyte GA-Z77-DS3H , and I also have Corsair Vengance 8 GB 1600 MHz but I'm not sure that really factors into this or not. Anyways if anyone could help me, I would appreciate it a ton!
