I've had to debug every install of docker for windows that I've done because it doesn't set something up correctly. Usually this involves googling the error message, finding a github thread where people are talking about which builds this affects, and then trying one of three or more powershell commands to fix whichever part of the install failed. In the most recent attempt, the error message told me to enabled virtualization in the BIOS, but it was actually that HyperV had not been enabled properly[1]. It was installed and the UI ran, but if you tried to start any VM, it would fail. I doubt debugging this sort of thing is feasible for an end user.
Docker Toolbox, although less polished, is based on VirtualBox and happily runs without Hyper-V. The only thing I've found missing is the control panel GUI.
