trying to install ubuntu 18.10 alongside win10 UEFI crashes

[Dclaw]

I am trying to install Ubuntu 18.10 alongside a brand new Win10 installation on a Dell XFR E6420 using UEFI.

Everything seemed to work fine, until it said it could not write to the drive. It is a brand new SSD, and only half of it was partitioned for windows. So it should have zero issues.
