Hi

The W10 Licence Activation Key is usually embedded on the MainBoard, and can be retrieved, and normally will re-activate automagically.   So no panic there, KeyFinderInstaller is quite good at doing the deed.

Next option would be try and repair the existing install, rather than wipe all data.

STOP the process.  PWR OFF.

Unplug from the wall.

If you see a battery compartment door, your computer has a removable battery. Remove the battery.

This is valid for most notebooks;

Press and hold the power button for 15 seconds to complete the reset.

Re-insert any battery you removed.

Next step is to make a DVD/USB if possible using the Microsoft Creator Tool...

If you can get this far please ask again.
