Windows 10 1703 upgrade won't run
This is an ASUS CM6870, i7 CPU, 16GB ram, wireless option, UEFI BIOS about 4 yrs old and came with W7 installed.
I clean installed 1703, but after install it does not boot but instead locks up with a bluish screen (not BSOD) and non-movable mouse pointer.
So I clean installed 1607 and it worked fine. I activated it and installed 1 program.
I then did an upgrade install to 1703 and again it bombed out as before.
I rebooted and it came back with a BSOD and indicated it stopped because of an inaccessible boot device.
Then it rebooted and said it was trying to fix it.
Then rebooted again with the same BSOD.
It rebooted again and proceeded to Restoring your previous version of windows.
How can the boot device be inaccessible under 1703 and not 1607???
