Using previous home partition after fresh install

[itzme]

Hello guys.

I was using Ubuntu, but I decided to move to Linux Mint

Code: Select all

$ lsb_release -a
No LSB modules are available.
Distributor ID:	LinuxMint
Description:	Linux Mint 18.3 Sylvia
Release:	18.3
Codename:	sylvia

I have two disks: ssd and hdd. So, / was set in the ssd, and swap and /home belonged to the hdd. I was reading some posts on internet but it is not quite clear for me how to do it.

For now, I can say I've installed Linux Mint and created the user with the same username and password. And this is my current info:

How can I proceed for adding correctly my previous /home (/dev/sda2) to my current setup?

[HaveaMint]

Whenever I have re-installed the same Distro / DE During install setup I tell it to format / and /boot (/boot if you run separate partitions for each / & /boot) keep in mind you still have to tell setup what each partition is meaning /home is /home but don't format home if you wish to keep it. So if you told setup what each partition is and whether to format or not it should see it when done with setup.

[Mattyboy]

As HaveaMint said just point the installer to your /Home partition and elect not to format it.

I'm not sure how installing a different distro ( it is Ubuntu so probably no major problems ) will effect how the system works with your old /Home .config files. So be aware that could be problematic.

edit your fstab file to include partition you want to use as /home
this is just an example (the system I am using at the moment), the UUID must be exactly the same ... no typos!
