Anyway, I have removed the second drive. Entered this into diskpart from the 50GB Windows partition:

DISKPART create partition id=af
Left out the primary size=n to make diskpart use all the remaining space; read this somewhere.

Got this:
EFI - create an EFI system partition.
EXTENDED - create extended partition.
LOGICAL - create a logical drive.
MSR - create a Microsoft reserved partition.
PRIMARY - create a primary partition.

I wasn't expecting this, but I've read on this forum also that OSX utilizes EFI, so at this point in time do I select the first option or just enter the size and so id=af ? The reason why I ask this is because when the partition is created using id=af from diskpart, I am unable to erase the partition directly. To do so I must boot from a Windows CD and enter Setup; kind of time consuming.

The computer is idle and awaiting a command, would appreciate if you guys don't take three hours to post a response.

Nicholas.
