Hi, Just about to install on a manually created partitions on my disk that already
has a root Ubuntu partition. i have carefully selected the partitions manually
and the root Ubuntu partition (the one I currently use) has the action: “Configure Format”
This means it will NOT reformat the partition, correct? My user
files from Ubuntu partition reside another physical disk so should be safe and are backed up else where.
Also I have indicated the pre-existing EFI. The installer
also says “Configure Format” for the EFI partition.
