hello, i'm trying to do something here and i'd be very glad to get your help. i followed one if the tuts to make a bootable usb with ML 10.8.4 with the lion diskmaker tool. anyway, when i set the bios setting on my HP pavillion to boot from usb - it doesn't boot anything. when i insert a windows 8 bootable usb it boots it perfectly. so we know the pc is set to boot from usb fine. i could not have been mistaken making the bootable usb because i just run the tool. what is wrong then? when i insert it and loads it on my mac, open up the disk utility and press on the info button - i do see it's bootable. and it's formatted as it should be. need your suggestion.
