The reinstalled system cannot be entered, and the boot items cannot recognize the hard disk.

The system itself has a lot of software running, and it can't be said that it is a problem with any software. If you press and hold the power button and don't move, it will turn off. Press and hold the F8 button when you turn on the computer again, and when the boot menu appears (Chinese characters), select the last correct configuration, and press enter to try it.

If not, you can restart and hold F8, the menu will appear to select safe mode, enter the antivirus, guard scan, and after processing, reboot and exit. If you can't get in, you can only reinstall the system. I didn't try it too much.
