Sager Boot Help

I don’t know what happened, but I was playing Fortnite, and my Sager NP6852 Froze on fortnite. I couldn’t do anything, it was stuck, so i shut it off. It sent me to a restart menu where it asked if i wanted to troubleshoot or turn off my PC, i clicked turn off pc (which might have been the fatal mistake.) Now, Whenever I try to boot it up, It says preparing automatic repair, Diagnosing PC, Reparing Disk errors, this may take over an hour to complete, then sends me to a black screen that says “Reboot and Select proper Boot Device or Insert boot media in selected boot device and press a key”

Also, idk how to edit my post, but i have tried going into BIOS boot settings, but all i see is something like UEIF settings and there are no options other than that
