From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Some BIOSes have trouble booting anything other than Windows, so some distros default to clobbering the Windows Boot Manager and trying to manage everything from GRUB. It sounds to me like this is what happened to you except it somehow got borked.
If the Windows install is still present on your drive it should be possible to restore the Windows Boot Manager. Then you won't be able to boot Linux but you'll at least be able to get into Windows.
Try booting off Windows install media and running Startup Repair using the following instructions: https://learn.microsoft.com/en-us/troubleshoot/windows-client/performance/windows-boot-issues-troubleshooting#method-1-startup-repair-tool
If that doesn't work try one of these solutions:

Good luck!

No joke, I'm trying to fix a family member's laptop's wifi issues while I wait.
So I'm somewhere between 6-10 hours
Also thank you!
what dot20 said was similar to what I had to do in order to get the Windows boot option back after GRUB couldn't find it after a Fedora install. As long as you can still see your Windows drive when you boot up the Windows Install Media, you should be able to rebuild its EFI entry.
As an addendum, here is a link to the Fedora docs for what to do in Fedora after you manage to rebuild Windows' EFI stuff.
Thank you, saving this as well
Between 6-10 hours of what?
edit: oh, you mean the xkcd, LOL. Well let me know if it works out for you haha
Yep, sorry should have specified 😄
Your notes were helpful and I'm saving them for future reference. Unfortunately I already decided to just try for a clean reinstall
