Ok so i tried to upgrade to Lion but every time it got to "7 minutes remaining" it would say "Lion could not be installed" And i called the Apple store and the man told me to delete my whole hard drive and restart i did that and it still won't work. My question is, on my windows machine how do i burn the "installed.dmg" to a DVD? Do i convert it to a ISO? Will my mac read that when i reboot? Or burn the dmg itself to the DVD?
