You only need to recover the partition ...not files.
That would be your best option.
I think we are all finding out about GPT disks.
Also, the MSR partition is hidden and does not appear in Disk management of Windows 8 and Windows 10.
So it behaves like a rootkit in that respect...
There is no real justifiable reason to have a MSR partition if your disk is formatted with MBR and you are happy with those specs for when running Windows 7..
MSR is not the EFI system partition which is shown in Disk Management.
I have noticed the MSR being forced onto people and their hardware with an update of the UEFI BIOS for certain machines.
The impact was not immediately felt and it was like a timebomb.
With windows 7, prior to UEFI, the MSR partition wasn't created and the OS ran well.
As mentioned, I upgraded from Windows 7 to Windows 10. It seemed OK at first ......
But like a timebomb....It destroyed my computer after I updated the BIOS and after Microsoft issued the Creators update for Windows 10.(October 2017)
When My computer was upgraded from Windows 7 to Windows 10, it did not contain a MSR partition at all and my disks adhered to MBR. It worked well at first.
My OS was trashed when they issued the Creators update and applied the update automatically even though I had updates set to prompt before applying..
They don't technically need MSR for certain machines and hardware.
They don't need to hide it either from the OS either.
You only discover the insidious part when you goto Rollback from Windows 10 to Windows 7 from an image.
Disk image recovery doesn't necessarily work with your archived known good images and the former partition table.... but it should.
I should clarify the paragraph above.
The image restore to the hard disk worked and the OS booted.
However, the OS no longer worked correctly and was unstable. We are talking a clean base install of the OS..
The current UEFI BIOS update does not play nice with the former Windows 7.
Note. Windows 7 failed to install seamlessly at first from known good install media.
...been working on a BIOS rollback now!
