I am trying to install Ubuntu 16.04 on my Dell xps 13 9350 as well. I have followed the step from this link: Install Ubuntu 16.04 LTS alongside Windows 8/10 in dual boot.
But I don't see the screen of step 2.7 (the screen where it detects that you have Windows boot manager and ask you what type of install you want) Instead it goes directly to the next screen (where you are supposed to see all your partitions) but it show nothing.
I am a bit stuck right now. Any idea?
sudo parted -l
andsudo lsblk -l
and/or a screenshot of GParted?sudo lshw -C storage -C disk
in your question.
