Dual boot - Fedora workstation - Fedora Jam

I have been trying to install a second instance of Linux on my computer that would be dedicated to audio/video editing. I want a real time kernel, ardour (I am a subscriber) ...the works. I have a separate drive for this to avoid any complications. I created a separate /boot and /boot/efi partitions and I was hoping that two installations could share the boot and boot/efi to boot the operating systems. I tried Ubuntu studio - that did not recognize the Fedora installation at all and did not install the boot loader. I also tried Fedora Jam that overwrote my boot partition and made my work computer unusable. The only distribution that was successfully detecting another OS was openSUSE but I wanted to get away from that. Anyone tried a similar setup? Two Linux distributions on one machine, loading different kernel configurations?

Fedora should not overwrite your /boot, unless you check the format option (or forget to uncheck it?!); but it will create a new grub2.conf which is supposed to contain options to boot other linux distros (if it does't, it is probably a bug which should be reported). But anyway, it is probably better to avoid sharing /boot.

I've never tried sharing the same /boot but sharing the same /boot/efi should work. AFAIK, having a /boot partition is not needed with /boot/efi.

The challenge is that /boot/efi will create a folder EFI that will have fedora inside. So you probably want a distro that doesn't have the same name.

If the two distros have different names, they should be able to share the /boot/efi no problem. Note that the "last distro" you install will likely overwrite the boot order and install a "fallback" in /boot/efi/EFI/boot/FALLBACK.efi. They install it under a few different names because motherboard manufacturers don't always follow the standards.

You can TRY to install rEFInd, nice eye candy, and should detect the different distros easily.

Do you think I can share the swap partition between the two systems?

Swap partitions can be shared. They don't hold any permanent data, they only hold temporary data.

You also technically don't need swap partitions. Swap files have been working fine for a few years.
