My EFI Partition is empty, is there anyway I can restore the Windows 10 files?

Thanks

How did it get to be this way?
Does the system still work? What errors do you see?

It was overwritten when I was trying to install a dual-boot, and the guide I used that was supposed to fix it just ended up deleting the partition completely. I've reformatted it to FAT32, as it should be, and with the correct name and everything, so right now it's just an empty partition.

I can start my computer fine, it just tells me there's no operating system and to press any key, and when I do it starts up into Windows just fine.

Boot from your Windows install media. Try the Repair function.
Otherwise....reinstall.

Repair does nothing, and completely reinstalling is hardly an appropriate option if I can still actually use it. Surely there is a way?

So hang on...
After pressing a key during startup, the OS boots up properly?

Pressing a key after a message is displayed about no OS being present. I can take a video if you want. The boot drive is set to the correct drive too

No video needed...I (sort of) believe you.
But I do not know how to 'fix' this.

can you show me a screen shot of disk management?

right click start
choose disk management
take screenshot and upload to imgur and share link here

Do you have more than 1 drive? curious which partition is active now

what motherboard do you have?

other then finding a way to add that partition back with the right files stored in it then there is not. if you are still able to access the OS partition then get into it and backup any necessary files and do a clean install of windows

there are ways to rebuild the efi files. It really depends what is active partition now, you don't necessarily have to have an efi partition, win 10 perfectly happy to run off one partition, its how my PC was set up for a while (only have 2 partitions now and neither is an efi)

Since you can get into windows, try doing a repair install - https://www.tenforums.com/tutorials/16397-repair-install-windows-10-place-upgrade.html, all you lose are the patches installed since that version of windows 10 was released and they will just download again. This assumes you are on Creators edition now.

So which disk had the efi on it as if you look here, its currently running off the efi on disk 1 - the ssd. The active partition is the one it boots off, and all the boot files appear to be in C ... Is partition E the one you emptied?

i was looking into how to restore an EFI partition like an MBR one and found a program called easeUS seems to be an easy way to restore it:
