Hi . My PC crashed when the Windows 10 boot SSD drive failed to boot. A computer technician installed a new Windows 10 on the drive, which now boots. But I've lost all my files and programs from the drive. Fortunately I'd created a system image on a separate hard drive. Not sure why the computer person did not restore it, but can I attempt it as it is or do I have to remove the new Windows 10 first? I'd prefer not to in case the attempted restore fails. I'd be grateful for any advice.
