Error : Windows could no prepare the computer to boot into the next phase of the installation

Fix : Disconnect all drives except the drive you want to install Windows 10.  This includes laptops.

Issue : Can’t reach login screen
Notes : Can happen after an update, auto repair should fix it
Fix : Start up the computer normal and when it starts to load windows force shutdown the computer.  Repeat the process 2 times, on the third start up it will Automatically try to fix the issue.

Other Issues

Windows 10 seems to be a little weird when you have two installs on two different drives and your trying to repair one.  I have had issues when trying to repair one, or boot into safe mode.  Removing all other other drives seems to resolve most of the issues.
