I've been trying to install Ubuntu 16.04 in VirtualBox (Windows 7 host), but keep running into the same problem regardless of what I tweak in the vm's settings:
This is the second time I've installed Ubuntu. The first, using the same .iso, ran into the same issue but eventually succeeded (wish I could remember what I did), but I deleted the first machine because I didn't know any better and wanted to have more memory for it.
What's even happening?
