Since I'm new to Linux and Ubuntu and have messed up my computer more often than a sane man would. So I would like to try something:

To run a computer with 2 120GB disks and on each disk have an encrypted version of Ubuntu 20.04.02. So if I mess up 1 there's the other!

I installed Ubuntu on each disk separately ( taking 1 out after the other). So now I have 2 vgubuntu groups with same name. I'm not able to mount the other one. This is of course a fabulous way of protecting me from myself. The drawback is that Ubuntu makes my life exciting by surprising me with the Ubuntu on sda or sdb.

Does anyone know a way to mount both? (I've tried to find it on answertopia (The Best!) but couldn't find what I was looking for.

And point to sda or sdb as the preferred startup disk?

If I can manage that then I can copy / backup files ready to go if I screw things up...

There is nothing wrong in having two devices with Ubuntu. However, encryption may not be a good idea, unless you have particular reasons. Same for secure boot. On each device you can have an EFI|UEFI system partition. Which one boots is decided at firmware level on your computer.

For example, on Mac, one presses the alt key at startup and is presented with a menu including both EFI system partitions.

TimeShift is just like Mac OS TimeMachine. It will help a lot I you lost files by mistake but if your only Ubuntu system breaks down, TimeShift may or may not save you, depending on small details that are hard to predict. Two working Ubuntu systems offer better protection.
