Cannot update Win 8.1 to Win 10.0 because of display

[James Moe]

host: opensuse 43.2, linux 4.1.13-5-default x86_64

guest: windows 8.1

Occasionally I get a popup to update to window 10. I say "Yes!" It then spits out this message:

... cannot upgrade ... The display manufacturer hasn't made you display compatible with Windows 10. Check with your manufacturer for support.

It then suggests I buy a new computer. I have tried this with the setting "Windows 8.1 (64 bit)" and "Windows 10 (64 bit)".

Is there a way to convince the upgrade evaluator that the display really is a marvel of modern technology?

You probably need to uninstall the Guest Additions, reboot the guest, then upgrade to Windows 10 and then re-install the Guest Additions. It is known that Windows 7 fails to upgrade to Windows 10 with the error message you provided but I'm not sure about Windows 8.1. Could you attach the VBox.log file of a VM session before you uninstall the Guest Additions?

You probably need to uninstall the Guest Additions, reboot the guest, then upgrade to Windows ...

That did not work. It results in the same unsatisfactory message.

Log after booting, then attempting the Windows 10 upgrade.

So you uninstalled the Guest Additions and then rebooted the guest and then tried to upgrade to Windows 10, is that correct? At which state did you grab the VBox.log file? The log file shows that the Guest Additions are still active.

No guest additions in this log. Booted, tried the update, same result.

Since removing Guest Additions made no difference, I just uploaded the available log. The second log did the same thing after removing Guest Additions.
