Win10 upgrade keeps getting stuck at 86%

simrick · 28 Jul 2016

Let's have a look at the error log:

C:\$WINDOWS.~BT\Sources\Panther\setuperr.log

You can post in code brackets using the "#" icon in the top-right.

One more thing: I assume, since you upgraded this rig once before, that the installation of W10 was "activated" and so you already have a digital license for this system, therefore the deadline for tomorrow's upgrade does not apply to you, correct? Did you verify the system was activated before you rolled back?

EDIT: You'll need to copy that log to your desktop, in order to open it in notepad.

See attached the requested file. Note that I hard-rebooted over 2 hrs after the last error. So these are not caused by the forced shutdown.

I'm wondering if there is enough free space on that system to successfully upgrade.

On the c: drive yes, see previous posts. 280gb free.

EDIT:

I had the issue with free space on a desktop with small ssd but there the upgrade would terminate on itself and fail and did not get stuck like here. (In fact with the upgrade tool it would not start at all)

Do you have Hyper-V and Virtual box both running on this system?

Please confirm:

I've asked for help with this. You've got a ton of errors in migration, and in the $WINDOWS.~BT. Let's see if anyone else here has any ideas.

Virtual box is installed but I have removed it now for trying again.

Hyper-V is not installed (or not that I know of).

Good question but I don't know if I activated it back then. So I'm working under the assumption the deadline applies.

Can I do a clean-install, activate and then move back to 7 and try an upgrade again after the deadline?

Different issue:

What happens when I upgrade my motherboard? (I have win 7 OEM version). If I then need to buy a win10 copy anyway, missing the deadline would not be a big issue then.

Yes.

If you currently have an OEM license, upgrading the MB will require a new license. So, yes, you will need to buy a copy of W10.

beginner99,

I saw this, and if you answer my question in the affirmative you're going to have to do a reinstall either with an OS disk or hopefully a saved image:

But remember the upgrade worked for me last Fall and nothing changed in terms of partitions since then. I reverted because it was unstable.

Does this mean that you have been working with this win10 upgrade since last fall?

Check to see if you have a Windows.old folder on your C: drive, if you do not then it has been deleted and you will not be able to revert back to your previous operating system (OS), in this case win7 and will have to do a reinstall of 7 from an OS disk or an image.

The Windows.old contains all of your win7 OS and if you don't like or are having problems with 10, 10 uses the .old folder to downgrade; But, you only have a 31day grace period to decide, if 10 sees no decision from you it thinks you are happy and on the 31st day it deletes the .old folder.
Does W10 upgrade delete windows.old files afer 30 day rollback period?
