Windows 10: Can't update to Windows 10 TP from 8.1

Hi

It seemingly installs fine, no errors shown, it checks my PC fine, accept the license then reboots. Windows 8.1 starts up as usual and nothing more happens. I check Windows update and each time I see it twice each time, successful and a failed with code 80070002 I tried all troubleshooting guides (deleting cache, temp files, and always end up with that error code, does anyone have some clue on this?

Thank you

:)

I am trying to downgrade from windows 10 TP to windows 8.1 . And having the error Package not available for this device . Tried all the tricks in the forums like uninstalling and reinstalling the Recovery Tool . Checking whether there are new updates for
my phone or not . Yet known of them worked . Really want to go back to 8.1 . I have been using the TP from the first roll out . Need help urgently

 

Windows 10 For Do It Yourself Builders

I know it can run but will it pull the windows 10 TP information(from 8.1) or the 8.1 pro upgrade information(W10 installed from)?

 

I would create a new partition and install from a flash drive or DVD

Thank you, do you mean a partition on the hard drive? I cannot create more as I could break things here.

I would like to upgrade it (NOT clean install) is there a way? I've searched and seems I'm the only one with this exact issue *facepalm*

 

ISO doesn't work either, (it goes up to 36% then a message saying Installation has failed pops up) so I will wait until the final version. Goodbye for now.
