Windows won't boot?

Question

Windows

The situation is this.
After the raid in the PC broke down, I took it out and put it in another computer with hdd on which Windows, I launched it, restored the raid, and of course I saw it, but under different letters. On the raid there is a local disk C and a 100 MB bootloader.
As a result, right now I inserted the raid back into the computer first, and Windows does not start, the boot logo appeared, but after that it goes into reboot.
I went into the console in recovery, looked at the volumes, and I see that the boot volume has the letter C, although it should not have a letter at all, but volume 2 under the letter D (it has Windows files and everything else, this is drive C).
Well, I’m so happy, thinking that everything is clear, I change the drive letters in the same diskpart, I reboot and it still doesn’t start, I go back to diskpart, and there everything came back and all my changes in the letters were down the drain. I looked at which volume is active, naturally this is the bootloader (if you put another one, nothing will be loaded). As a result, I understand that the bootloader simply does not know where to look for Windows files and, of course, it does not load anything.
How to solve this problem? How to start Windows, what pedals to turn, what tambourine to use?

Answer 1

Drive letters are assigned at the operating system level, not hardcoded to a drive.
The fact that the letter was changed in the recovery mode, this only affects the assignment of the letters of the recovery mode itself, which will be reset upon reboot, because. its state is not saved.
Through the recovery mode (by F8 at the time of boot), run "boot recovery".
And it would not hurt to specify the version of the installed OS ...
