Been trying to install Win10 preview on my Surface Pro 3 (win81.) for months. Windows update won't install it, nor will the downloadable ISO files. The last 3 ISOs (including the latest 10162) give me the same error:
0x80070002 - 0x20007
The installation failed in the SAFE_OS phase with an error during INSTALL_DRIVERS operation.
I tried the Windows update, I tried downloading and running the ISO (two different ways - keeping files and removing all) and I also tried the boot from a USB to the ISO. Every time I've tried it get about 30% or so into the install, and then it reboots and just says it's going back to the previous version of windows). After that I'll log on as normal and get that above error message.
Again... this has been the error with the last 3 ISO builds. What am I doing wrong?
