How to move bootloader from HDD to SSD drive C?

Question

Windows

Good afternoon!
The other day I ran into a problem, I decided to take out the HDD, I start the computer, and he swears that the system or drivers were not found,
stuck it back, it all worked.
the system is definitely on drive C (SSD), but the bootloader, as I understand it, is on drive M, please give me advice, what can I do (without reinstalling the OS)?

Answer 1

EasyBCD or something similar.
Well, there are native Microsoft console utilities, but they are more difficult to deal with .

Answer 2

# Really transfers the bootloader and all the necessary files to boot the system to the system disk
bcdboot c:\windows /s C: /l ru-ru /f ALL
(Substitute your letters)
so try it. straight out of Windows. or with winPE
you have disks in MBR? I do not see any additional partitions for the bootloader. apparently everything is on the unit. section.
