Hi, everybody.
I have a little problem with installing Snow Leo 1.6.2 by Hazard on my PC.
I have my SATA mode set to AHCI and there are no problems with installing any of Leopard (1.5.6, 1.5.8) distros, but this one doesn't want to cooperate though.
When I try to boot install DVD, it shows me the bootloader screen (you know : "Press any key to start (...) or F8 to (...)"). Then it seems to start booting, but after a few seconds it boot me to Windows (which I have installed on that PC). I also tried booting installer with "arch=i386" but it didn't make any difference. When I tried booting it in verbose mode, it shows a few lines stating, that OS X installer is booting, but after a few second the screen goes black, and then I got my Windows again.
If it could help, I've got AMD Phenom II x4 based PC, with Gigabyte mobo with 790X chipset and SB750 southbridge.

Does anyone know, what's wrong and can help me ?
