managed to dualboot win7 and mountain lion quite easily from a fresh install.
have to thank the hard work of many people over many years which allowed me such a painless process, lol.

specs:
intel q8300,
asus p5p43td pro,
ati hd4670.

process:
boot usb unibeast,
format 2 guid partitions - 1 mac journaled, 1 msdos fat,
install windows 7 on fat,
install macosx,
run multibeast->easybeast.

easybeast might not bad the best(?), but everything seems to be working fine .

@digswell
