Windows 11 Boot Option Gone After Installing Bazzite

Bazzite
1

I have an existing Windows 11 install on a separate SSD. After installing Bazzite the option to boot into my Windows 11 install is gone, both in the boot menu and in the Bios.

I’ve had this happen twice now after installing Bazzite, once over six months ago and again just yesterday.

I’m wondering if this is fixable, or do I need to reinstall Windows 11?

I’m also wondering what I’m doing wrong during install that my Bazzite installation is rendering my Windows 11 unbootable every time I install.

Did you already try this after installing:

Dual Boot Preliminary and Post-Installation Setup Guide - Bazzite Documentation → regenerate grub

I just tried ujust regenerate-grub and my windows install is still not showing up.

Hey JG - does your motherboard see the both SSDs (even if it doesn’t see a bootloader)? Did you install windows with secure boot enabled and then turn it off? (you can install Bazzite w/ secure boot enabled)
