The computer is a small form HP desktop running Window 10. During the process of installing Windows updates the computer crashed. I received a message stating that the computer had incurred a problem and that it needed to be restarted. Over the next fifteen minutes this same message was received. I started getting a message that "Automatic Repair was being performed. I received this message several times. A new message appeared as follows: "A critical system driver is missing or contains errors" Also shown on this message was the following: "Error code :Oxc 0000221" & "Windows\system32 \drivers\[email protected]". It futher stated that I would need recovery tools or a system disk. I can not get the computer to reboot. What is the best way to fix the problem. Any suggestion would be greatly appreciated.
