Ok, brother-in-law accidentally put the wrong power cord!
Windows 10 PC no longer boots and the Windows system partitions are foobar.
The C: drive looks completely intact.
So is there a way to recreate the system from that C: drive? I have extra drives to copy stuff back and forth if required and extra PCs.
Tried all sorts of windows commands to recreate systems partitions but just cant get it to boot :-(
