Hey there,

What boot loader did you use?
Did you change or add any kexts?
What version of bios are you using?

I have exactly the same build with a GTS250 card, can't get it to boot for the life of me

Tx!

Dude,

Nokext installed, i just use basic of basic from multibeast, try a lot here but nothing....i don't no my bios Ver, but i will see it and tell you. I try it 5 times since 15th. On Lion, everything works VERY feel, not even need -x neither -v, just install multi beast and go to party.

i Guess i will work with lion while more.

I GOT IT!!!!
ML is fully work! I got video kext on the osx86.com for my video card, replace in S/L/E, them i run multi beast with normal options and select Repair permissions. I got some kext errors, ignore 'em them a reboot and voila!

If you receive a BOOT0 error follow the fix steps show in tonymac forum.
