Issue solved: 2-6-2022

After uninstalling Linux OS from ROG by deleting the partitions and the booting system through the diskpart command prompt, more of it is explained here https://www.youtube.com/watch?v=znnqvlHyU2k, this is not the real issue but the Bitlocker was. 

I restarted the computer, the ROG Zephyrus laptop and it showed a blue screen with a box asking for a Bitlocker recovery key, I tried to move around to the UEFI but it didn’t work, so I went to Jordan's computer in the study room and logged into his computer and his Microsoft account and found the Zephyrus device and click on manage encryption and found the one with Bitlocker recovery key, I inserted the key into the box in the Zephyrus and it worked. 

Issue solved!
