I currently have my main hard drive split into two partitions. One being Windows 7 with about 600 GB of memory, the other Windows 8 Consumer Preview with about 50 GB. As you can guess it is set up for a dual boot. Today while looking up how to get the C# Facebook SDK for Metro apps I learned about the Release Preview being released. I was wondering: How do I go about getting rid of Windows 8 Consumer Preview and replacing it with the Release Preview? I know i can't just wipe it off my second partition because the dual boot uses Windows 8 to choose the operating system to boot.
