Win10 install broken after update.

[Myst_]

Windows bluescreen on boot not long after update. "Critical Process Died"

Booting into safe mode gives same result.

"Reset this PC" returns error.

Chkdsk finds no bad sectors.

Sfc /scannow:

"Verification 100% complete.

Windows Resource Protection coule not perform the requested operation."

I have no convenient way to access Win10 boot media.

I'd just like to congratulate you all on being so amazingly useful.

For posterity:

Solution, back up data using Windows Recovery Environment cmd prompt onto secondary drive. Hard reformat boot drive and install fresh windows.
