I want to erase elementary OS completely and install Ubuntu 19.04 The installer offers me with 2 choices:
Install alongside (which I don't want).
Something else (I want to keep windows and install Ubuntu replacing elementary).
What next steps should I do? Which partitions should I remove/modify?
Here are my partitions:
Formatting the ext4 partition (or deleting and re-creating it) is sufficient to get rid of Elementary.
Personally I would go a less destructive route: install the ubuntu-desktop package on Elementary (it has Ubuntu under the hood after all), reboot and login to Gnome/Ubuntu. Optionally clean up Elementary repositories and packages after that.
backup your important Windows files FIRST
boot to a Ubuntu Live DVD/USB
start gparted
delete /dev/sda6 and /dev/sda7
quit gparted
double-click the "Install Ubuntu" icon on the Desktop
choose "Install along side of Windows"
