How do I restore the recovery partition in windows 8.1

For some reason, the recovery partition on my computer is gone which means I can't do a restore or a full reinstall of Windows. Here are some screenshots as proof.

Here's one of the "This PC" window:

If the recovery partition were still functional, we'd see it as a separate hard drive with a capacity of approximately 8 GB

Here's a screenshot of me attempting the reinstall

So does anybody have any idea on how to fix this?

I am asking because I was told in my previous question VirtualBox won't open. Error code 0x80040154 that I would have to reinstall Windows if I don't have a restore point, which it appears I don't.

If your recovery environment is missing, for what ever reason, you will need to either contact your system vendor/manufacturer (such as Dell, HP, Toshiba, etc.) to acquire a copy of restoration media which is the preferred method, this may or may not reinstall your recovery environment but it will definitely allow you to re-install Windows that was originally shipped with your PC. An alternative would be to use Microsoft's Media Creation Tool although at the time of this answer attempting to download it is resulting in a 404 - Not found error, and it appears Microsoft has removed it in favor of Windows 10. Another alternative would be download and burn the full Microsoft ISO file to disk for Windows 8.1, which is available on the Microsoft Downloads site.
