Hello to everyone. I have followed this tutorial and have some problems. My Hardware: GA-P67A-UD3-B3 Ver. 1.1 i7 2600k ATI Radeon HD 5870 1GB XFX 2 TB Harddrive 8GB RAM The installation went well, but after the update and MultiBeast installation i can't boot without the iBoot cd. And the Sound doesn't work. If i start without the iBoot cd the following error appears: Loading Operating System ................... boot0: GPT boot0: test boot0: test boot0: GPT boot0: test boot0: test boot0: error I have also tried to install Bridgehelper and MultiBeast with and without the DSDT. It would be great if someone could help me.
