So I want my hard drive to be partitioned out as so:

1) 375GB Apple OS X Lion 10.7.3
2) 60GB Apple OS X Mountain Lion 10.8 DP1
3) 315GB Microsoft Windows 7 Home Premium x64

However, I noticed I'll run into several issues.

1) The partition map says that I'll have the Windows Partition to be Partition 5, which won't work because MBR only allows up to 4 partitions in active, unless I'm wrong here.

2) When I tried to install Windows after partitioning, I got a GPT error. We use EFI 1.1 on our MBP so of course Windows will not allow installing under GPT since it requires EFI 2.0

3) If I were to install Lion + Windows 7, then partition out Lion for Mountain Lion, it breaks Windows, causing it un-bootable.

Has anyone run across this issue before? If so, how were you able to fix it? Any help is appreciated
