Windows fails to start but can still see data through command prompt

I have a desktop computer running Windows 10. The fan was making a noise so I cleaned it out. I think I was too aggressive and sprayed the compressed air right on the SATA connection to the SSD. Anyway, next time I turned on the computer it went into startup repair mode and gave the error

A required device isn't connected or cannot be accessed Error code: 0xc000000e

I rebooted a few times and got a different error message:

Your PC did not start correctly where it gives me the option to choose advanced options and open a terminal

I tried following the instructions here and here but they did not work. When I run bootrec /rebuildbcd it gives "Windows Installations 0" and the directory C:\boot is missing. I ran checkdsk and believe it repaired some things. I disconnected secondary hard drive, all non essential peripherals

Through the command prompt I can access my files so I know at least that's still there. What's the best way to proceed?

You have 2 options.

Option 1

You can attempt a windows repair using your computer's recovery disk or windows installation CD.

On the Choose an option screen, select Troubleshoot. From there, you can:

• Restore from a system restore point by selecting Advanced options > System Restore. This will remove recently installed apps, drivers, and updates that might be causing your PC problems. Restoring from a restore point won’t affect your personal files.

• Select Reset this PC to reinstall Windows 10. This will remove all apps and drivers you installed and changes you made to settings, but lets you choose to keep or remove your personal files.

Option 2

You can carry out a complete reinstall of windows using the recovery disk or windows installation disk.

If you choose Option 2

remember to back up any data you wish to keep on your windows partition.

If you don't have either your recovery disk or windows installation CD

you can legally download a free copy of Windows 10 installation CD using a working computer. Just go to https://www.microsoft.com/en-gb/software-download/windows10

When installation asks for a product key just say you don't have one. Because you already had Windows 10 installed and activated, it will reactivate automatically.
