Ubuntu 20.04.2 Disk Partition

Asked by tomdean on 2021-05-27

I have some strange problems with my system. I think this may be my fault. I have re-installed 2 times recently and want to make that easier.

The last install of Ubuntu 20.04.2 divided the disk into 5 partitions, two overlapping. Strange.

I want to go to a divided disk partition scheme.
nvme01p1 200G Ubuntu
nvme01p2 32G swap
nvme01p3 768G /home

With nvme01p3 mounted on /home, I can install and not have to restore /home unless something goes wrong.

If I do this, are there any obvious problems?

Will the Ubuntu installer allow installation into nvme01p1 and not touch the rest of nvme0?

I think the installer will just install everything into nvme01p1, including home. Then, I zap home and mount nvme01p3 on /home/me? Maybe use swapon nvme01p2?

During installation you see a dialogue about disk partitioning (user whole hard disk or install besides already existing operating systems or something else). If you select "something else" you can set nvme01p3 a target for /home. Just be sure __NOT__ to tick "format" for that partition.

N.B.: creating a backup copy of /home before that actions is definitely a good idea. If everything goes ok, you will not need restoring, but whoever knows ...

Can you help with this problem?
