As the title says, I’m trying to multiboot Fedora 40 and Ubuntu 24. The documentation and guides for this all seems pretty outdated through my searching and troubleshooting.
I currently have ubuntu installed. My drive partition table looks like this:
- sda1 – EFI (250MB)
- sda2 – /boot (ext4, 2GB)
- sda3 – empty (ext4, 2TB) <-- Fedora partition
- sda4 – Ubuntu 24 (LUKS encrypted, 2TB)
I’m trying to install Fedora now and it’s giving me nothing but errors. The most useful guide I found for this specific setup just has you adding sda3 as the installation path (mounted at /) for Fedora and it’s supposed to figure out the EFI and boot, but that doesn’t happen. In fact, the EFI and /boot partitions show up under an “Unknown” tab in the Fedora custom partition window of the installation. They should be under a tab such as “Ubuntu 24 LTS”. Fedora isn’t recognizing the ubuntu installation (because it’s encrypted?)
Am I wrong in assuming that both OS’s should be sharing the EFI and /boot partitions? Maybe that’s the issue?
Anybody out there successfully dual booting Linux distros with both distros encrypted?
don’t share /boot
it contains stuff from the distro for booting and configuring/installing a boot loader. if both garble their stuff in there it will likely break.
