Need help restoring UEFI boot partition

(I posted this in the begiers forum but feel like this may be the place for it, let me know if I should delete one or the other)

Hi everyone,

I've only been using Ubuntu for development for a few months, and am still leaing my way around.

Last night I accidentally formatted my boot partition. I had windows 10 and ubuntu installed using grub bootloader. The drive is ptk (i believe).

I am getting an error when ruing boot-repair about gpt drive and needing to create a partition with a boot flag, but I've seen various (old) Idea online about how this is the wrong thing to do.

I have the info dump on pastebin if anyone would like to help.. I don't have the windows cd anymore and there is a lot of important data on the disk so I would love to get this working again.

Thanks
