3. using chown and chmod, set the permissions and ownership correctly.

4. Set it as your new /home partition

For that type

sudo blkid

Locate the UUID of your old /home partition.

Edit the fstab

sudo nano /etc/fstab

Add the following text to the fstab file on a new line, replacing the xxxxxxxx portion with the full UUID of your old home partition

UUID=xxxxxxxx    /home     ext4     nodev,nosuid     0     2

Rename your current home to home_old and create an empty /home folder

cd / && sudo mv /home /home_old && sudo mkdir /home

5. Restart
