MBR to GPT: Please hear me out before redirecting me to another thread

Hi guys!

I want to convert my BIOS-based Windows 7 Ultimate 64-bit to a UEFI-based environment, and to do that, I need to go from MBR to GPT. I know that numerous guides have been posted on how to do this, but my hard drive is special and I want to preserve the data on the drive as well as its integrity.

My hard drive is a WD Black2 dual drive. I have it configured so that it has Windows 7 installed on the 120GB SSD portion, and I manually moved the page file to the 1TB 5400RPM platter since writing to the SSD greatly diminishes its lifespan, along with my files. The thing is, the drives on which many guides on MBR to GPT are demonstrated have only 1 partition. Since my Black2 is one drive with these two separate components, I have two partitions: C and D. I have posted a picture from disk management to show you what I mean. If I follow the guides on the internet, I will most likely lose the SSD portion and mingle these two portions into one partition, which is my worst nightmare since then I don't know what part of the drive is running on the SSD or HDD.

So, I have a few questions:

1. Is my D drive, the 1TB platter, under MBR or GPT?
2. Can Windows 7 use my C drive using GPT and use my D drive using MBR? I know I must convert one drive at a time
3. What should be my first step, after backing all my data up, for this process?
4. I activated this 1TB platter using a driver from WD that I installed into Windows 7. Do I need to uninstall it to make my WD Black2 one partition again?
5. Can gptgen work with one partition from this drive (i.e. only C or D), or must it work with the whole entire drive?

Thank you in advance!
