I am trying to upgrade from windows 7 to windows 10.

Hi,



Thank you for writing to Microsoft Community Forums.



I understand that you are trying to upgrade the PC from Windows 7 to Windows 10. For further clarity on the issue, please respond to the questions below:

1. Where did you purchase the license from?
   
2. How did you perform the upgrade?
   
3. Did you receive any error when the PC restarted?
   
4. Do you have any third party anti-virus software installed?
   

Meanwhile, I would suggest you to make sure that Service Pack 1 for Windows 7 is installed, and the PC meets the

system requirements for Windows 10



You can follow the suggestions from the article

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
