No Root File System is Defined

[Michael Lantz]

Got in a batch of Dell Latitude E6410 laptops that I am trying to install Linux Lite version4.6 on. All is well until I get into the "Installation Type" screen. It is preset to load "Device for boot loader installation:" to /dev/sda. When I click on "Install Now" I get the following error message: Under the title "No Root File System" box it reads: "No root file system is defined" "Please correct this from the partitioning menu". Then the system takes me back to the prior screen.

Question: I formatted a drive before going through this install procedure. When i click on the "+" under "Change", the install crashes. It looks like the system does not see the sda drive. Any help would be appreciated.

Thanks
