Solution: When I formatted all my drives to install Linux on one and Windows on the other, I kept both connected and they share EFI boot partition as a result. Every time I reinstall Linux it formats the drive and therefore deletes the Windows’s EFI Boot as well. One way is to fix this is to reinstall Windows while disconnecting the drive you have Linux on. Or you can move the boot files if you don’t want to do that.

I used this guide: https://forums.tomshardware.com/threads/changing-windows-boot-manager-drive.3571420/post-21561626

Also remember to delete the Microsoft folder in the boot folder on Linux after you’ve checked that the new boot loader is working.

OP:

Currently dual booting as I need Windows for a few tasks and ganes Linux just won’t do. Since setting everything up I’ve reinstalled Linux twice, both times I’ve lost the ability to boot into windows and have needed to reinstall it.

Disk doesn’t show at all in Grub, tried all kinds of things but it just doesn’t show as a bootable OS. It doesn’t show in the boot options in the BIOS or the boot menu for my motherboard. Drive shows up and all the files are still on it. So my guess is the Windows bootloader somehow installs on the same disk that I have Linux on.

I run Linux(Fedora) and Windows on two separate drives.

Windows take forever to install. Anything I can do now to prevent this from happening if I need to reinstall Linux or if I wanna to some distro hopping?

Just to be clear, everything is working right now. But I want to prevent having to reinstall Windows every time I change distro or reinstall my Linux OS

    I was hoping to avoid that, but that’s gonna be my next move.

    Unless I forget and break windows again. Words can’t describe how tired I am of choosing the 37 different options during the install, updating the OS 4 times and installing my apps and deleting bloat. 😂 Windows 11 is great and all, but Microsoft loves to make it unbearable to use.

      Install Windows, but leave drive open or a partial space on windows drive. When you install Linux, don’t let it install the EFI boot into the Windows EFI boot partition. Instead have the partition manager build a new boot partition+root home etc. Grub will install on its own partition, OS prober should find the Windows drive too, and it will add a chainloader entry to grub. Set your machine to always boot from Linux grub, if you want windows you select it in grub and it hands boot over to windows boot. This way they are isolated and Windows never knows that Linux grub exists and will leave it alone.
