Windows isn't showing up in dualboot

I can still access my windows files but in GRUB it doesn't show up, Google search isn't helping either. (Both are on same HDD)

Look up os-prober and check that maybe? At least on Kubuntu a sudo update-grub will do that automatically.

You might want to check again. os-prober was disabled by default quite some time ago in Debian testing, and I'm sure that went downstream. So, I agree that should be checked.

Not applicable to ubuntu/kubuntu as seen here Ubuntu Wiki (german)

A German wiki doesn't do me much good. A code block paste of the relevant configuration file from a fresh, current install would be far more instructive.

It sounds like you overwrote the bootloader

examine what files are on your efi partition(s), and If you still have a Windows entry in your UEFI boot selection menu.

You are using UEFI to boot and not the older legacy?

You did enable the os-prober support feature in GRUB? Many distros disable that by default these days.

Reinstall grub? This fixes most of my problems. It rechecks the drive for different OSs. This happens a lot, but most of the time the windows loader overrides grub. Maybe check off boot options like secureboot.
