windows blue screens on startup and cannot enter boot menu after trying to install grub2windows

[1supercomputertyler]

I dualbooted linux on my pc build (1700x, gtx1070, asus prime b350) and it worked fine but I did not get a boot menu to switch between the two. I then installed a software called grub2windows which is supposed to give me a boot menu but I got an error on installation. thought I would just try again later and shut off my computer but now when I turn it on it takes me to a blue screen and restarts infinitely. the error reads kmode exception. is there a way for me to fix this without reinstalling windows? I am in a really big time crunch because my semester just started and any help would be fantastic
