I want to add a second version of Ubuntu to my existing xubuntu 20.10 desktop machine, I want it to be a dual boot system.
I just want to end up with a boot menu that defaults to the existing xubuntu 20.10 installation but will allow me to choose Ubuntu (server) 20.04 at boot time if I need to. To add a slight complication my 20.10 installation has a separate /boot partition and drive because the main NVME SSD isn't visible to the BIOS. So I have the following drives:- /dev/nvme0n1p2 ext4 48174 15748 29912 35% / /dev/nvme0n1p3 ext4 896193 295874 554727 35% /home /dev/sdb1 ext4 10016 183 9306 2% /boot /dev/sdb2 ext4 109596 33138 70850 32% /scratch /dev/sda1 ext4 938772 222399 668664 25% /bak /dev/sdc1 ext4 937872 77 890087 1% /mnt The new Ubuntu Server installation can go on /dev/sdc1 as that's empty. What's the easiest (and least error prone) procedure for doing this? -- Chris Green
