I just installed Mountain Lion on my new H77 build.
MB Asrock H77m
CPU Intel i3 2120
VGA EVGA GTX 560 Ti Superclocked
HDD 2X WD Black + 1 SSD
BIOS setting: Ethernet OFF, Intel Smart ... OFF, I left all HDDs connected and no changes of CPU, MEM stuff...
I keep getting "can't find mach_kernel" when booting from Apple Raid 0 helper partition. I followed the method for snow leopard, using Hackinstaller to setup boot loader on raid partition, but seems there is some system file missing there. Has anyone succeed?
