You might also run the free
MICROSOFT COMPATIBILITY TEST prior to attempting your upgrade again. It's built-in to all W10 installs. If you fail to see it or missed it, you can download it and run it standalone on your PC to see if it's got driver or app issues that would keep it from performing the W10 update properly. You can get that here:
Get Windows 10 app - Check Compatibility Report for Windows 10 Be aware that there are hardware limitations to running the W10 OS. Specifically, if your PC was built before 2005 it will
NOT work with W10 due to issues missing in the CPUs that old. One of our volunteers has reported running on a PC with a 2004 BIOS; but I cannot reproduce that on any machines I personally own. This doesn't appear to be your problem, since your machine came with Win7 it was sold in 2009, but may have a BIOS date of 2008. This could be a problem if you bought that machine prior to Aug.2009 and it was an early release machine. Microsoft officially supports W10 upgrades from all W7x and W8x OSes.
HOWEVER, on Vista era machines as well as XP machines, some early release W7 machines (c.2008) have not been able to run W10 via upgrade.
But, you can do a Clean Install on them, and get them running that way, and bypass the upgrade process altogether. I've had to do this on a couple of machines here in order to run W10. The
COMPATIBILITY TEST will help you with this, as it's an indicator that your hardware may be too old to run the Upgrade tool. If that's the case, you can attempt the W10 Clean Install. If this fails, you can probably figure that machine will never run W10 no matter what.
Here's the link for the W10 Clean Install:
Windows 10 Scroll down the page to
"PERFORM A CLEAN INSTALLATION USING A USB OR DVD". This section covers the Clean Install as well as gives you the MCT tool to grab the ISO file needed.
The problem of some early Win7 machines not running the upgrade to W10 is not that well known yet, and usually only W10 Insider Testers such as myself and some of the other folks here have been through it. Microsoft may be able to help you via the Upgrade path; but it's a
$39-$149 phone call to do so. Some of our Users here have had success doing a 2-step upgrade; that is from W7-->W8.1x and then W8.1x-->W10; but this requires you to have or purchase a W8.1x license. I suggest trying holdum's idea and my suggestions above and see if you can get it to work!
Best of luck to you,
