So I have a partition setup like this:

Click image for larger version

The first partition is a Windows Repair/Setup USB.
The second partition is a file storage.
The third partition is an image file of my entire system.

I have this set up so that if the Windows 10 upgrade fails on my computer, I can revert back to Windows 8/8.1

Will I be able to boot into the first partition and use the first partition to reformat the PC, and use the first partition again to reload the system with the third partition that has a windows image?
