Bootcamp - Create new partition and format in Windows 7

Hello All

I have Windows 7 installed on my sons MacBook Pro.

The Drive is partitioned at 500GB for Windows and 300GB for Mac.

In windows, I need to shrink the Windows drive, and then create 2 extra drives from it.

However, I can shrink the drive, but when I try to Format, it tells me that it cannot find the drive, and then it changes the drive types to all "Dynamic" including the Mac Drive.

And once this happens, I can no longer access the Mac drive during Boot, and windows will not load, as it cannot find the drive during windows boot up. And which point, I have to restore the system and it takes up to 6 hours to installed Lion, as my Internet is slowing that a cold winters day.

So, my question is the following.

How can I successfully shrink the drive.

Then Partition the FREE space

Then Format to NTFS without loosing drive type and integrity?

Thanks All

MacPro may be a bit fussy, so you can try with just a single designated drive and attempt an EFI installation. W7 may not work, but W8.1 does. I am aware of Audio and Graphics issues with an EFI installer on older Macs.

Yup, it always works as expected if I don't already have a Windows partition on the drive ahead of a Recovery partition being created. As you can see in my previous post, there is a Recovery partition on the drive I have Yosemite on (partition still named Mavericks). If I were to install Win 7 or Win 8 on that drive, then the Recovery partition can still be created since there's already a spot for it underneath Windows, but OS X won't put one above it.

The Bootcamp assistant relocates Recovery HD (and you can see the movement if you use Testdisk and look for partition changes).
