Dell OptiPlex 7010 came preinstalled with Win 7 64 bit and a Win 8.x DVD. Original partitions are intact.
We needed to restore the pc to Win 7 factory settings as pc is playing up. We went into Windows Recovery (F8 at start up and Recovery option). Tried Dell Backup and Recovery, nothing happened.
Rebooted into Win 7 and used the Dell Backup and Recovery software to create the factory reset USB media. Booted from the media and still Dell Backup and Recovery option does nothing.
Downloaded Dell backup and Recovery software with new interface. It tries to prepare environment for a long time and then fails and uninstalls itself.
What are we missing and how can we reset the pc to the Win 7 factory settings?
