Windows 10: Desktop won't boot properly Reboot and Select proper Boot device/Repairing disk errors loop

I had opened the Epic Games launcher on my computer, and it had blue screened my computer. It sent me to the reboot and select proper boot device screen. I've seen this before, usually I just go to bios, load Optimized Defaults, then fix my boot priority. However this time, that didn't work. Instead, it said it was running diagnosis, and preparing an automatic repair. This process has run multiple times, staying on "Repairing disk errors. This might take over an hour to complete." anywhere from 4-12 hours.I've tried looking up several solutions, however none seem to work. I've heard some say I

Reboot and Select Proper Boot Device...after reboot?

Hello all. Getting a little frustrated here. A couple of weeks ago we had a user come in on a Monday morning to find that her pc was displaying the classic message "Reboot and select proper boot device...". Tried popping in a windows disk and fixing the MBR, no luck. Ended up reinstalling windows and her few programs back on it. All was good after this. For about a day. She came in the next day to find the same message. So at that point we decided that more than likely the drive was bad even though oddly enough it tested out fine. It was a Corsair 60gb SSD.

Last week we swapped that Corsair with a 64gb Crucial SSD and installed Windows. We then created a backup image of that drive. All was good until Thursday when her power strip that the PC was plugged into got tripped. Start up the computer for find "Reboot and select proper boot device..." message. So, apply the backed up image to the SSD since repairing the MBR didn't work.

Now this morning she comes in and the PC is running fine. Attempts to open Microsoft Word and she gets a pop-up stating there isn't enough disk space. So, she then restarts and upon booting back up gets "Reboot and select proper boot device..."

Any ideas what is causing this? Is it something with the mobo or do I just have horrible luck and replaced the bad SSD with another bad SSD?

 

Desktop won't boot properly (Reboot and Select proper Boot device/Repairing disk errors loop)

No, it just goes to the Reboot and Select proper Boot device screen

 

Reboot and Select proper boot device or insert boot media in selected boot device

My computer was working fine with Windows 10 then I started to receive the error "Reboot and Select Proper Boot Device"

I only have the Windows 8.1 CD. Boot sequence is correct and when I try booting from the Windows 8.1 CD and select repair-> advance+ trouble shoot-> repair start up it just keeps looping back to re install??? If I take the CD out I get the Reboot and
select proper boot device message.

Please help I can't do anything with the computer
