I have an older Windows 7 Professional x86 install that I am trying to upgrade to Windows 10 Professional. Hardware is a mini-ITX with i3 4170, 4400 HD graphics, 4gb memory and 250gb SSD. The install was originally Windows 95 OSR2, possibly upgraded to Windows 98, then upgraded to Windows 2000, XP, Vista and finally 7.
The installation halts on the first boot, after the files have been copied, with the black screen, Windows logo and spinning circle.
I have been trying to upgrade this install for nearly three years. Is there some way to debug the upgrade process to find what's blocking FIRST BOOT?
