I'm sorry if I'm opening a new post about G31M-ES2L but reading 70+ pages of posts is simply mindblowing.

The reason I'm writing is to know something more about the installation techniques that - apparently - don't work with my want-to-be hackintosh.

In brief, I've thoroughly followed the rules about preparing a USB stick that contains OSX Snow Leopard, I hit F12 to choose the drive to boot but... the computer keeps booting from the Windows 7 hard disk.

At this point I'm wondering if i have to unplug that Windows 7 hard disk and/or leave plugged that HD where I will install OSX.

is there a preferred SATA port where OSX HD must be plugged?

Thanks in advance
Michael
