I am trying to install Ubuntu 18.04 on my computer.
I have a hard drive that looks like this:
sda - sda1: /boot/efi - sda2: /boot - sda3: [LVM:ubuntu-mate-vg] - swap_1 - cryptswap1 - /home - /
Now when I use USB Live 18.04, it can't detect any existing operating system. What I would like to know: how can I install 18.04 on a new LVM partition, keeping my current configuration working? Of course, I will reduce my existing configuration and make space, but I am concerned: where do I choose to be the boot partition for this new install? Where do I put the root? How would you add it to grub?
