Ubuntu – “/home partition” after formating and reinstalling Ubuntu 18.04 on “ext4 /”

home-directory

if i install ubuntu 18.04 on a fresh disk by creating

EFI Partition 500mb
EXT 4 / Partition 100GB (sda2)
EXT 4 /home Partition 100GB (sda3)

after some time if i format EXT4 / Partition (sda2) and fresh install Ubuntu 18.04 on it.

What will happen? will it create a home folder in sda2 or it will leave my /home in sda3? will i loose my data on /home (sda3)?

  • What you describe is my SOP.

    Do a backup, you are one ticked box away from losing it all.

    When you go to do the fresh install, select “something else” option in the installer.

    Tell it to use your / partition, mount it at /, and tick the format box.

    Tell it to use your /home partition, mount it at /home, do not tick the format box.

    Tell it to use swap if you have a swap partition.

    Then proceed with the install.
