I installed Fedora 38 with disk encryption on BTRFS. The BIOS of my machine automatically send me to the unlocking password on whatever the latest kernel I installed is.
This is not what I want at all.
The machine is a dual boot with Windows. That is on another drive, with its own boot loader. But that’s not important right now. What is important, is that I want to see the grube2 menu and choose which OS I boot. This is how it worked when I had no disk encryption.
The reason your grub2 menu is not showing is likely not related to the encryption but to the fact that Fedora/Grub hasn’t recognized the second OS yet.
