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)?
