Mount Veracrypt encrypted system drive

I encrypted my laptop (a Lenovo Yoga 700) with Veracrypt because I was to cheap to by the Windows 10 business version.  Later, the laptop died (display problems). I should have read the "print these instructions" better.  I bought a SATA M.2 (which is the "hard drive" which looks like an old memory stick) to USB adapter and plugged it into another computer with Veracrypt installed. 

I tried to mount it with long waits and screens that say things about "incorrect password" and "not sure this is a volume".  After playing with VMs to try to boot off the rescue USB and worrying that I would never see my data again, I tried to recreate the problem by encrypting a Windows 7 VM.  In the process, I read the "print these instructions" window. 

It says quite clearly to open Veracrypt, select the device, select a drive and select 'System' > 'Mount Without Pre-Boot Authentication'.  Then enter your password.
