I've experienced this problem as well on Ubuntu MATE 16.04.2 LTS, but managed to resolve it.
This issue seems to be related somehow to the existing partition table of the drive: even after manually creating a new GPT table in gparted (or KDE partition manager) I got stuck at this message, but if I created a new partition table for the blank drive inside "something else" the message did not show up (dispite the fact that it also creates a GPT table if I'm correct). I assume that's why the default install method worked for everybody here - this step must be included in that one as well. Reproduced this three times (error and resolution as well). Hope this helps somehow to the devs. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1418706 Title: UEFI: blank drive incorrectly detected as existing BIOS-mode install To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/partman-auto/+bug/1418706/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
