Glad you got it working, and yes, Clean Installs solve lots of stuff. But, there are 2 things that we've seen here on this forum and other forums I volunteer on that cause the upgrade to fail:
#1: If the
Win7/8/8.1/8.1.1 computer isn't running healthy to Microsoft specs prior to the upgrade, or doesn't have enough free space (at least 9GB free) on the hard drive prior to the upgrade, W10 isn't going to work at all, will generate an error message code, or will just hang or freeze and never complete.
#2: If you are doing multiple upgrades, you need to really pay attention to running the free Microsoft-provided W10
COMPATIBILITY TEST here:
Get Windows 10 app - Check Compatibility Report for Windows 10
This test utility is included in every copy of W10 internall within the installer program, but can also be run separately to check if there are programs or malware or outdated/incompatible drivers that would cause the W10 installer to fail. People who know about this such as professional computer repair techs know to run this program first. Correcting the problems found by the Compatibility Tester utilitiy allows the upgrades to proceed in about 90% of the cases. This program has been around for many years, all the way back to Win98 and XP; very few home users know that they should be running it or that it even exists!
Several reputable online e-zines such as PC Magazine & PC World have commented that the majority of people who fail to run this utility often fail their 1st attempt at a W10 upgrade. It's well documented.
For other forum users with failed W10 upgrades, this post can let you in a little-known secret, and get you going again. Then if the upgrade still fails, you can try the above Clean Install as mentioned.
