What do I do now? FUUUUCKKK WINDOWS !!!

What happened?
Can't you just click back and boot into Windows?

Startup repair is usually the logical option though 😉

Install gentoo

Or use UEFI firmware settings to boot a bootable flash drive or CD. 🤗

just go back and startwindows normally, if doesn't work startup repair... of course usual comments like: "linux, linux ftw, linux rocks, switch to linux, install linux, windows sucks, ms sucks...." cannot be skipped... without even know what kind of sotware and programming language do you need to use, and also like linux is perfect and cannot have any problem
