Greetings,
I’d appreciate any experience anyone has similar to this issue and/or suggestions about which files to look into to track down the issue.
I have Manjaro installed with grub properly set up with windows detected and added to the boot menu.
I just installed Gentoo on another drive with the following layout
sda1: swap
sda2: gentoo-btrfs
- @ : Gentoo root partition
- @home : Gentoo home partition
I went through the process of installing the Gentoo base system, configuring and comping the kernel, and and setting up the system to be ready to boot into. I did all this by chrooting into the btrfs volume from Mnajaro. This is why I did not include a /boot/efi (efi system partition) in the Gentoo installation process, as would typically be required. I want to simply use the Mnajaro GRUB to launch into any of my, no 3, OS’s.
When I run update-grub
on Manjaro,

The output says it detected Gentoo on /dev/sda2, but when I reboot, it does not show this as a menu entry.

Thank you in advance for any ideas for tracking this down!
