I have currently a dual boot system with debian an windows® 8.1 bit installed.

As I use ᴜᴇꜰɪ, I use the windows bootloader to load the linux kernel directly (I compiled the linux kernel as an ᴜᴇꜰɪ application).

I have many application installed on windows, and for some of them, I lost the serial key necessary to reinstall them. So I don’t want to perform a fresh install (upgrade to windows® 10 while keeping installed applications).

After cloning my hdd to a backup one, I used the gwx tool and ended up on this error message after the download phase. Which translate to :

An error occurred.

Sorry, but we can’t determine if your computer is compatible with Windows 10. Close this program and try again.

Of course trying again or rebooting still lead to the same error.
It also worth to say that with 16Gb of ʀᴀᴍ ; 900Gb of free disk space, and an Ivy Bridge ᴄᴘᴜ, their should be no hardware compatibility problem (so it’s safe to force the install).

So is their a way to find why the installer fails to determine if my computer is compatible ?

  • I did two Win8.1 to 10 upgrades, one of which dual booted with Ubuntu, and both went seamlessly using the Win10 ISO (I didn't boot it, but mounted it as a Windows drive and ran setup.exe). My one upgrade from Win7 was awful, with repeated failures like yours (though not the same message), and I tried so many things that I cannot now remember what eventually worked. If you're not using the ISO, maybe you could give it a try. – AFH Jan 5 '16 at 22:18
  • @AFH : I tried the iso and got exactly the same issue. I also tried through Microsoft update, in which case it fails without any specific error message. Because I backed up everything sector by sector, crashing isn't a real problem (though restoring would take 4 hours). You probably got the same error message since my translation come from mine as I couldn’t found the original English message. – user2284570 Jan 5 '16 at 22:22
  • I don't think it was the same message, because I got an error code which eventually led me to a solution. Your translation is good, but you would need to know the exact equivalent message (which may not be a literal translation) for a search, though you may just strike lucky with the French language version. Apart from that I don't know what to suggest. – AFH Jan 5 '16 at 23:59
  • @AFH the search on the french version lead to nothing. There should be more and better messages with the original english. But is their really no way to bypass compatibility checks? – user2284570 Jan 6 '16 at 0:02
  • I searched for "Un problème est survenu." "Désole, nous ne pouvons pas déterminer si votre PC peut exécuter Windows 10." and one of the links was headed "Windows 10 update : error 8007001F - Microsoft", so I searched for this and got a few more links in English. – AFH Jan 6 '16 at 1:01
