I'm trying to install Ubuntu 16.05 on a PC with a blank NTSF formatted hard drive. I get to the part of the installation that wants you to choose a partition to install to and that's all the further. The dialogue box does not list the partition I created on the hard drive. However, if I simply boot Ubuntu without installing it see's the drive. I've tried the install using a USB stick and a DVD with the same result. What am I missing?
