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 :)
