Windows fails to start because the installation media isn't present on an empty hard drive.
Your Windows 10 is running smoothly on your SSD. The other drives you mentioned are just game installations and don’t have Windows set up. When you tried to select a boot drive, the BIOS showed your SSD as the boot device even though it was still plugged in. You might want to check the BIOS settings or try removing the SSD and connecting it directly to test.
Ensure you understand that when you mentioned moving the files, the drive contains no Windows-related data—it's just games and nothing else.
You shouldn't try to relocate the boot files. Reinstalling is necessary, or keep the drive connected during installation. Disconnect other drives while setting up Windows to avoid random placement of boot files.
The files @191x7 aren't visible in the file explorer window. Navigate to disk management, and you should see an additional partition on the "B" drive.
