Discovered that Windows limits names to 15 characters during install, as the provided link states, RTFM lol but the custom prompt allows longer. ('Read-Host -Prompt 'Enter computer name';)
The PowerShell window accepted the longer name but later during reboot, started getting the BSOD, tried this on a couple of machines, same issue..
Changing the custom name back to one less than 15 characters seems to have solved it..
Hope someone finds this helpful.
