Hello I have found a very peculiar problem when running windows 8 on a late 2010 21.5" intel iMac.
My situation is that i can install and run windows 8 nut as soon as i go onto mac os x lion, it just goes into installation, say no bootable disk found or open startup repair.
this generally happened for no reasons but recently it started only doing it when i would modify a partition in disk utility.
it started only doing it when i would use disk utility once i installed bootcamp on windows 8.

If you could give me any help please post.

p.s. if anyone tells me there is another post on this topic I'm sorry i couldn't find it but thank you.
