Made a new partiton to update to 10.8, now I am screwed

[NinjahKitteh]

Okay so, when mountain lion came out, I was quick to jump and decided to install it. Instead of installing it over my current lion, I decided to make a new partition on my hard drive for Mountain Lion. Now I have my main boot up running on this new mountain lion partition, and I still have lion on this computer, which I dont use. The issue I am having now is that I am trying to figure out a way to put windows on here without deleting my Mountain Lion. I really don't care if I delete the lion partition, but whatever I do it doesn't seem to work. When I boot, it lets me pick Lion or Mountain Lion. I do already have a bootcamp partition with windows installed on it but for some reason it doesnt let me boot inside of it. Is there any way to get this to work? If I delete my main partition with lion so that I only have mountain lion on here, will I be able to boot inside windows. Sorry if this is confusing for you, I am a bit discouraged because I worry that the only possible way to do this would be deleting Lion and Mountain lion and doing a full clean install of mountain lion. Thanks for the help
