    Windows 10 Upgrade / Rebuild Issue


    Hi,

    I upgraded to Windows 10 on my Windows 8.1 device. After I upgraded I came across an issue with a driver (or similar) which meant that my machine was unable to boot into Windows.

    The only options were for me to rebuild the machine and wipe or rebuild and keep all my files. There was no options to do anything else... none of the other options worked.

    I did rebuild and keep files... The machine rebuilt, all my files are retained and I am able to use it again.

    HOWEVER - I HAVE A PROBLEM!

    I am now unable to return to Windows 8.1... I think the rebuild has removed the option to return to Windows 8.1 because it is a rebuild off of the Windows 10 installation files, not Windows 8.1. I can still see the Windows.old files and folder, I also know that the required installation information is all still present as the Disk Clean Up (system files) still shows them.

    I need to reinstate the Windows 8.1 roll back button on my machine but there is nothing to explain how. Nor can I find a KB to show me how I might do this using a command prompt or similar.

    My device does partially work in Windows 10, but not fully. This is so incredibly frustrating as I have lost a lot of the free subscriptions that were included in the laptop as well (such as office personal and mcafee) because the rebuild uninstalled them all.

    Can someone tell me how to get back to the Windows 8.1 on my machine??

    And before you ask NO I do not have a back up and / or image of the machine as I was asked to upgrade when I turned the new machine on - it went straight to Windows 10...

    This is a brand new laptop!

    Thanks for this. I was aware of this, but was keen to see if it were possible to get the button back rather than do a fresh install. I won't get back Office doing this approach...

    Win 10 pro Upgraded from 8.1

    Well didn't you get a restore disk from the manufacture? if not you could look in there support website for the restore disk Image. This would get you back to the condition the notebook shipped.
