trying to install lubuntu on virtualbox vm

[ubername]

Trying to install lubuntu 16.10 on virtualbox vm. I went round some loops having tried to use encryopted disk and LVM, neither of which the installer liked. Switched these off and got the crash. Maybe somewthing to do with the vm having an autoresize disk?
