Can you provide a bigger image.
Does the other disk consist of any other file or it empty.

EDIT: Do you have any other PC.

If you don't have any files in other drive or if you can delete the files in other drives.

This might solve your problem.

1. Boot from either your Windows 7 installation disc and press Shift + F10 when at either screen below.

Solution 3: Convert GPT disk to MBR disk via diskpart command

In the following case, I would like to convert disk 0 into MBR disk.

1. Open command prompt.

2. In the command prompt, type diskpart and press enter

3. Type list disk and press enter.

4. Type select disk 0 and press enter.

5. Type clean. (This will wipe out your drive.)

6. Type convert mbr and press enter.

11. Type exit and press enter.

I have Edited this method to make it easy & short.

again, you can boot from Hirens, and change the GPT Disk to MBR Disk.
Any modern (AOMEI, MiniTool, EASEUS) partition manager has that option...

But guys already helped you as I can see :)
