Accidentally deleted EFI file on Ubuntu in the Bootcamp disk.. Help!

[Serdar Sağdıç]

Hello. I will tell all the steps i did.

1) I was using MacOS and Windows installed with Bootcamp (50GB) not a single problem.
2) I decided to install Ubuntu for my works. Then created a USB bootable Ubuntu disk with Etcher (same install method in Ubuntu's website).
3) Installed Ubuntu into the Bootcamp disk. And gived 10 GB to Ubuntu. (Bootcamp decreased 40GB)
4) When I choose "Bootcamp" in boot menu (after holding option key) it started Ubuntu all the time. Then i decided to delete Ubuntu.
5) I tried to delete 10 GB Ubuntu partition in Ubuntu disk assistant and I couldnt. (it's funny, isn't it?.. ).
6) Then accidentally deleted 315 MB EFI file in Ubuntu disk assistant. While i did it, i cant see "Bootcamp" option in boot menu.
7) Tried to delete Windows with Bootcamp Assistant ant it says:
"Boot Camp Assistant cannot verify if Windows is installed in the Windows partition."
8) Tried to format this deleted partition and it errors.
9) Here's my GUID partition map. Please help.. I want to recover this Bootcamp partition and delete Ubuntu in it. Or if i cant do it, delete everything in my 500 GB SSD and install a fresh OS (i have a time machine backup. How should i do it?
