I installed Xubuntu on a pcie ssd to use side-by-side with Mint. But, I still want to use Mint on its current SATA ssd drive. Ideally, I'd like to make sure that the Xubuntu installation is bootable (I haven't been able to yet), and then have an entry for each in Grub. I have a boot-repair USB for executing any grub commands or generating more info.
I've tried several different combinations of grub installations, but so far no luck. Is there a canoncial way to add a xubuntu distro to grub, assuming I want my current drive (Mint/SATA) to handle grub management?
Here's my lsblk output (excluding snap/loop devices)...
sda 8:0 0 111.8G 0 disk └─sda1 8:1 0 108.4G 0 part / sr0 11:0 1 1024M 0 rom nvme0n1 259:0 0 477G 0 disk └─nvme0n1p1 259:1 0 477G 0 part /media/alpha/xubuntu
sda1 is where my current Mint distro lives.
