Change boot back from efi to mbr

A quick explenation to my problem, so I formated a drive with an old windows installation on it (not the one qurently in use) and it hade my boot records on it, so I got the error bootmgr missing. So a bit panicked I used the first solution witch was "bcdboot c:\windows /s h:" from the command prompt from a USB with a windows ISO on it. That fixed it and I could now boot in to windows and everyting worked.

But this made it so i'm booting with EFI insted of MBR. So i'm booting with a boot option on my H: drive witch is not my windows instalation drive witch is C:. The C: drive is MBR and the H: drive is GPT. Is there a way to fix it so that I can choose my C: drive in the bios to boot from. So remove the efi and use mbr instead.

First, we need to see a screenshot of disk management:

Make sure to widen the data columns so we can see all the data.

Also, just curious, what is the issue with booting in UEFI mode?

Here is the picture


C: is where my windows is and F: is where my EFI folder is.
It's is not a problem to boot with this method, it's more that I want the boot records to be on the C: drive as well.
Sorry if this was not clear from my first post. And the boot record is located as a normal folder on disk F:.

The command would be:
bcdboot C:\Windows /s C: /f BIOS

Then reset your UEFI settings to boot from Disk 0 in legacy BIOS (CSM) mode.

Can I use this command from a cmd inside windows or should I use it from a ISO on a USB?

Inside Windows

I copied that command in to a cmd inside windows and then restarted my computer and went in to the bios. But my C: drive is still not recognised as a bootable drive.

Only my F drive is recognised as a bootable drive (both in the picture).
I have my bios set to recognise both UEFI and legacy boot devices.
THe mother board in question is a "Asus ROG Strix X570-F Gaming" if that helps.

Edit: Both the C: disk and the F: disk is mbr, a correction to the original post.

Run:

bcdboot C:\Windows /s C: /f ALL

When I copy that command in to a CMD I get the error "Failure when attempting to copy boot files".

Edit: From inside windows.
