This is an infuriating bug, but I've found a workaround, more or less described in a comment in a duplicate bug here:

I'm installing Xubuntu 16.04 amd64 on a completely blank SSD on a brand new UEFI-enabled HP system. If I immediately create an EFI partition (say 200 MB) before the main partition, that doesn't fix the bug. I still get the broken "Force UEFI installation" dialog in the next step.

This is because, for some strange reason, the installer decides to set the EFI partition to ext4 instead of FAT32. You can see this in the space allocation graphic at the top of the manual partitioning dialog. So, instead of directly creating an EFI partition (during which you can't specify the file system type), I created a 200 MB FAT32 partition, then changed it to EFI with the "change..." button, and voila, I now have a FAT32 EFI partition. After allocating my root partition and hitting next, I no longer get the broken "Force UEFI installation" dialog, and installation proceeds smoothly.
