We are glad to answer for you: The methods for accidentally deleting computer system files and not turning on the computer are as follows:1

In the system, press and hold the F8 key without touching the withered release, and start the computer repeatedly, and it will enter safe mode.

2.Use the system to restore the original key to the beam: Once the system restore function has been enabled, you can try to use the system restore to restore the system.

In the system, you can press the win key + r to open the run window, enter, and then press the enter key to open the system restore window, and select a recovery point to restore. 3.Reinstall the system:
