Installing Windows 7 on a GPT drive

Hello,

My hard drive was formatted with GPT. It is part of a volume group and has two logical volumes on it. Is it possible to convert the drive to MBR? If so, how would I got about doing it? I know there are programs out there that do it, but I have volume groups with LVM's so I am wondering if it is possible in this case.
