Hello there ! I'm new in this forum and I learnt about your method 2 days ago. So I have a problem (of course ? ) : I can boot with iBoot supported, and after launching SnowLeo CD but here come the problem : Everything is sloooow and there is some graphic bugs. Is this my graphic card (GT220) that is not supported ? Or do I need to try with iBoot Nvidia ? Thanks in advance !! (Hoping that I'll be able to put OSX on my PC) EDIT : Okay don't know why now I have the same problem as viewtopic.php?f=3&t=2745 In fact the same screen problem appears. It tells my that I have Kernel 10.3.1. EDIT2 : Okay, I don't know why but actually it works. I just updated my bios. So I have One last question, I made a partition in windows (with a software) so I have 2 partitions with one full of my windows folders, apps, etc... and the other, free and empty. But I cannot press the "Option" button and choose "GUID partition table". Is there a way to do it or do I have to erase everything ?
