Windows 10: Build 10074 sits at "Just a moment..." on clean install

I am trying to dual boot Windows 10 with my work laptop running Win 8.1. Every time I try to install it, I get to the settings portion of the install and I just choose "Express settings" and after that it says "Just a moment..." with a spinning circle of dots, but never does anything after that. It has been sitting like this for a couple of hours now. Has anyone else had a similar issue?

Windows 10 Build 10162 won't install.

Windows 10 Pro Insider Preview does require a activation key. It is available from the Microsoft ISO download site. Version 10162 will not complete the "clean" install. It goes all the way to a pale blue screen with spinning dot icon and the words "wait
a few moments" and it never clears. I have a dual-boot setup with Windows 10 Enterprise Insider Preview version 10074 that installed and is working fine on the same hardware... Version 10162 tries to install automatically inside Windows 10 Enterprise Insider
Preview version 10074, but it reports "trouble installing" and we'll try again later

 

Enter on keypad " no. + # "

petrib is correct. It is a shortcut to SIM numbers.

Numbers on your SIM might not be in the position you think. Just because they appear sorted in alphabetical order in the contacts list doesn't mean that they appear in that same order on the SIM. On the SIM they appear in the order in which you input them,
unless you delete a number in which case the next one entered takes its place.

 

If you haven't yet, please refer to Shawn's Tutorial for dual booting. Take note of the warning regarding UEFI.
