[demigod]

Thank you zep. You really made it easy.my installation was smooth and got finished in 19 min
after booting into mac i came to know.my audio,lan card and graphics (working in default res) are not detected.

while installation i choose customize and selected NVinject for XFX-Nvidia 7300GS and for audio i selected all since i don't know what to choose (bad idea..) .after booting into mac i got some error for those plugins which i selected for audio and then i deleted those kext file in system\library\extensions.Now no errors as well no sound.

for video lex23 made a post.but no joy for me.still in same default resolution.
