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.

Are you booting in legacy BIOS or UEFI mode?
Legacy only supports one bootloader per drive, which should be grub. If you're in legacy mode, windows was probably thrown out of there so it doesn't show up anymore. Grub can still call the windows bootloader if you configure it accordingly.
The arch wiki page on grub has a section explaining the details.
It's UEFI from what I can tell, at least that's what comes up in the BIOS
In your BIOS do you have the option to add a new boot entry?
On my Dell laptop, I lost my Windows boot option once, but all I had to do was go into the BIOS, add a new boot option, and point it to the Windows EFI loader: EFI\Boot\Microsoft\bootmgrfw.efi
(I'm going off memory, so I could be off slightly with the path)
From what I remember, there weren't many options in my BIOS. I'm not sure if it's just my device or something else.
Someone else mentioned that I could have used the Windows 11 installation media to launch a terminal and fix it that way, but I had already cut my loses at that point and did the reinstallation.
My windows will only boot on legacy, and Mt Fedora will only boot on UEFI. This means I have to change bios settings to go from one OS to the other. Not ideal, but whatever.
Classic windows moment, you have to reinstall it to change that.
Yup. Just don't feel like dealing with it when I seldom go into Windows anyway. If I must use Windows, I usually use my work laptop.
