I wonder if anyone could help.

So my system was configured as follows:

1Tb WD Black SN850x as W11 system drive.
2Tb Samsung 980 Pro as game storage
4Tb Crucial P300 Plus as extra game storage

I have just bought a new device so i copied the files from the 2Tb drive to the 4Tb drive which was fine and the system booted correctly. I removed the 2Tb and fitted into my Legion go, formatted, installed steam os all worked fine (Sorta) But my main pc will now not boot. Somehow it appears as if the windows boot manager was installed on the 2Tb (But all the windows files such as program files etc were on the 1tb) somehow and in removing it has caused it not to boot. I was just about to do a new reinstall to get it sorted but wonder if there was any boot manager fix tool? I saw something that was related to the recovery environment however i am unable to access that as windows does not boot.

Any help would be appreciated.
 
When you say "copied the files", did you literally copy the files over in Windows, or did you clone the drive using a drive cloning tool?

No sorry, i was unclear. I copied files from the 2Tb to the 4Tb such as the Steam library, Epic Library and other software that runs from the .exe rather than having to be installed. Then the drive letter of the 4Tb was going to be changed to the drive letter the 2Tb was using previously. I did not do anything with the system drive (1tb WD).
 
Without access to another PC
Start pc
Do a hard shutdown by holding power button
Repeat 3 or 4 times
Should boot into recovery environment
Use cmd prompt and bootrec commands
Bootrec /scanos
Bootrec /fixboot
Bootrec /fix mbr
Bootrec /rebuildbcd

With access to another PC
Download 30 day trial of macrium
In it make bootable rescue usb
Boot the rescue usb
In it there's a very good simple to use
Fix boot issues tool
Doesn't 100% of the time fix it
But certainly more times than the bootrec commands do

Or Download windows installer on a usb
And get to cmd using that
