I advise a friend who purchased Paragon HDM17 (3 licences family edition) on my recommendation. He used it to make image backups on a USB hard disc of his Windows 10 system.
*He did NOT make a recovery DVD or USB*.
He has inadvertently re-formatted his Windows 10 version 19.09 "C" drive, so lost all system and data. He has asked to buy a recovery disc by email but he has had no reply from Paragon.

My question. If I downloaded the community Backup & Restore version onto another computer and made a back up DVD, could it be used to restore his image to his non-booting -working Windows 10 hard disc from his USB back up.
My version HDM 2015 works with my old Windows computer. From its restore DVD, I can can see his archive on his external USB hard disc, but cannot restore it.
Do you have any advice how I can help him?
Thanks in advance for your help.
