I can't tell you if this is the issue or fix. But I did run into that and the HDD in the laptop had a failure so the restore worked after we put in the new blank HDD.
I bought my laptop Lenovo z51 , few months ago with it I got Windows 8.1. Then when Windows 10 update came, I updated my windows to windows 10 and made a System Image Backup and stored it in my external hard disk. Now becasue of some issues my windows got corrupted. When I try to recover my windows using my system image backup from my hard disk I'm getting this error message
The system image restore failed
Error details: The processor architecture or OS version of Windows Recovery Environment is not the same as that of the computer that was backedup.....
Can anybody tell me, how can I resolve this issue.
