Now we are back at the partitioner display, and it shows the selection for the root filesystem.
Unfortunately, the UEFI Boot gets even more confusing here. It still doesn't show that it is going to do anything with the EFI partition (you can't see it here, but trust me, that part still looks exctly as it did two screens ago), and now it is still giving you a choice of the "Device for Bootloader installation". What the heck does that mean?
If it is going to do a UEFI Boot installation, then it will install the bootloader to the efi partition, so why does it need you to select anything here? Or perhaps you are supposed to select the EFI parition?
Or is it going to make new EFI partition for its own use, like Fedora does by default?
Or is it going to install the legacy boot loader to wherever you select here? I just don't understand what it wants.
All I can tell you is that I am paranoid enough that I don't want to risk having it install the bootloader to the MBR (or turn the entire SDA device into one huge EFI boot partition? Ack!), so I always change the partition that will contain the root filesystem.
To be honest, what I suspect is that when doing a UEFI Boot installation, this input field is ignored, but I have never seen that documented anywhere, so who really knows for sure?
When I click on "Install now", ubiquity will do just that — it goes off in the background and starts performing the installation. At the same time, it will progress to the next screen and continue the user input.
