URGENT HELP - Old Windows 7 upgraded to windows 10, NEW SSD and RAM. No longer works when booted.

I have this really old ASUS K55N laptop, I added a new Kingston SSD \[160GB\] and installed windows on it. It worked for a couple of months until I booted it up one day and now it wont work. It keeps saying "Innaccesible boot drive" with a BSOD, I even tried to fix the BIOS settings, but nothing worked. I wiped it clean through the cmd prompt and reinstalled the installation for windows and it still gives me the same pop-up and issues. I tried to remove the disk tray from it, which is my suspicion why it wont work anymore.

Another thing is that I can no longer get to the windows CMD prompt by using the repair kit that comes with it, as it just sends me through a look of pressing f1 to enter repair space, then it sends me back to it again, again, and it repeats.
