How do I fix my PROSCAN plt8990-K if its missing file: \windows\system32\winload.efi

Question

I have tried to google this problem with as much different wording as I could but it hasn't lead me anywhere, so sorry if this is obvious I'm no good with this, but when my tablet starts up the first notable thing I see is "preparing automatic repair" under the Proscan logo, it then brings up the following screen:

However that's also not the only error I get, as stated in the actual question I also get this error:

So for one I don't know why the error changes, I also don't have any idea how to fix the issue. It does say I'll need a recovery tool which I may have a usb around, but what do I do with it? As always any help is much appreciated.
