Windows 10: Error Message while upgrading Windows 10 Home to Pro Edition

Hello,


I had a valid Windows 10 Pro serial key which I used to upgrade my old Lenovo laptop came with Windows 10 Home. It worked perfectly. I did it 6-7 months ago. I sold that laptop recently and didFull Reset before selling. So the key is no longer in use.

I bought another laptop today and it came with Windows 10 Home as well. But When I am trying to upgrade it to Pro edition with my serial key like before, it's giving error in random screenshot below.





what's wrong? one retail key works in single machine? I can't re-use the key to another machine or what? Need help here.


Regards.

:)

Upgrading from Windows 10 Home to Windows 10 Pro -- Cannot upgrade to edition error

Hi Likhitha,

• When exactly do you get this error message?
  • When I login back to my PC after a restart.
    • The restart is done after trying to upgrade my Windows Edition: Windows 10 Home to Windows 10 Pro through:
      • Go to Store > "I have a Windows 10 Pro Product Key
      • Settings > System > About > Change product key or upgrade your edition of Windows

    • Current Edition:
      • Windows 10 Home
      • Version 1511

• What is the exact error message you are getting?
  •

Here is my service request no.: 1317870824.

I was given the solution to download the ISO at https://www.microsoft.com/en-us/software-download/techbench and I see that the ISO is already a 1511.

Not sure on how I can upgrade to a Windows 10 Pro with my product key.

 

Error Message when updating from Win-7 to Won-10

Bree
I followed your suggestions (2nd Aug 19) for installing Win-10. Made the bootable flash drive successfully through the media creation tool. But when I attempted to upgrade and activate to Win-10 (64 bit) from within Win-7 (Pro-32 bit), I got the following error message:

Error # OxC1900101-Ox20017. " The installation failed in the SAFE_OS phase with an error during BOOT operation"

I read the diagnostics under this error number and carried out the proposed fixes, i.e. update Win-7, uninstall Malwarebyte antivirus, disconnect all external hardware, e.g. printer, scanner, external hard drives. I then tried to repeat the steps to do the upgrade through the Win-10 bootable flash drive as before. Got the same error message.
Appreciate any further comments and suggestions as to (a) what does a failure in the SAFE_OS during boot operation mean, (b) what can I do to solve it. Is this anything to do with the hardware in my computer? I listed these in my first posting above.
Thanks for any help
