Inaccessible Boot Device BSoD error

[Christheman24]

(This is the error message after the boot up)

Hello, I recently did an experiment regarding the transfer of files from my host laptop (Got it in 2021) to an older HP laptop (Got that one in 2018) with the SSD/HDD drive. After that was successful, I returned the drive back to the host laptop and was able to boot up somewhat normally. Here's the situation, I then get sent to the Recovery BitLock Screen where there I entered my Recovery Key which then proceeded to the boot up. When it got to the HP Logo, the boot up would freeze and end up going to a BSOD with the error code "INACCESSIBLE BOOT DEVICE". I have looked up online and watched tutorials on how to fix this said issue, however it doesn't end up working well because the tutorial would tell me to reset the computer to access the Windows Recovery Screen or the Advanced Options screen to reset it, etc and when I would reset the computer, it takes me back to the BitLock Recovery Screen, reenter the key, and take me to the advanced options screen but little to no resources to help out. 

I know this was a lot to write and it maybe confusing but to sum it up in a better way:

"My laptop starts to boot up with the BitLock Recovery Screen, I reenter my password and it would show the HP logo but then it would freeze and display the Blue Screen of Death with the error code "INACCESSIBLE BOOT DEVICE"" . All hard drives, battery and other parts are in working order and all the wires are connected properly and untouched.
