'We Couldn't install Windows 10' Error - 0x80070005 - 0x2000A

Anyone had the following Win 10 install fail in the SAFE_OS phase during PREPARE_FIRST_BOOT ? Been testing on a couple of our Win 7 devices and both failed with this error.
Answer
Answer
  • Disable (preferrably uninstall) your Antivirus utility before attempting the upgrade.
  • Disable General USB Devices (example - Smart Card Reader). 
  • Do a clean boot and try again.
  • If you are upgrading using the .ISO file, disconnect from the Internet during setup, if you are connected by LAN (Ethernet) or Wi-Fi, disable both and attempt setup again. 
  • If you are updating through Windows Update, when the download reaches 100% disconnect from the Internet LAN (Ethernet) or Wi-Fi and proceed with the installation.
  • If that does not work, try using the .ISO file to upgrade if possible.
  • If you are connected to a domain, switch to a local account
  • If you have any external devices attached to the machine, disconnect them (example, USB keys, external hard disc, printers, non-essential devices).

    If you are installing Windows 10 using Windows Update, try the following:

    1. Press Windows Key + X on the keyboard and then select “Command Prompt (Admin)” from the menu.

    2. Stop the BITS, Cryptographic, MSI Installer and the Windows Update Services. To do this, type the following commands at a command prompt. Press the “ENTER” key after you type each command.

                               net stop wuauserv

                               net stop cryptSvc

                               net stop bits

                               net stop msiserver

    3. Now rename the SoftwareDistribution and Catroot2 folder. You can do this by typing the following commands in the Command Prompt. Press the “ENTER” key after you type each command.

                              ren C:\Windows\SoftwareDistribution SoftwareDistribution.old

                              ren C:\Windows\System32\catroot2 Catroot2.old

    4. Now, let’s restart the BITS, Cryptographic, MSI Installer and the Windows Update Services. Typethe following commands in the Command Prompt for this. Press the ENTER key after you type each command.

                            net start wuauserv

                            net start cryptSvc

                            net start bits

                            net start msiserver

    5. Type Exit in the Command Prompt to close it and then restart the computer.

Ok, here's what we did, fresh factory install of origional Win 7 O/S, full updates loaded via Windows Update, by full I mean every single one, ISO fresh load of Win 10 and it all worked, there are a couple of other issues that come up like : 1. Unable to enter Settings 2. Unable to turn windows updates on and a few other niggles that I will raise elsewhere but all in all works well ;)
