EFI System Partition

[WKN]

Does anybody know what this is and what it does to affect my PC?

I did a re install of windows today, before i did a re-install it just said system re severed, After formatting then re installing it says EFI System partition & I noticed in my BIOS "Windows Boot Manager" which is something new.

Any Idea?

Alright re installed, but when reformatting it didn't decide to use the 100mb as System Reservered. What should i do with this unallowcated 100mb? I made it into a volume and tried extending it onto my SSD but that wouldn't work

Thanks
