Hi Dang
I am Sumit, an Independent Advisor and a 2-Year Windows Insider MVP here to help.
Let us try repairing the existing OS.
On a working computer, create an Installation media of Windows 10 that allows you to repair existing Windows Installation.
Create a USB Flash Drive

Boot from the USB Flash drive-Make sure you have disabled Secure boot/Fast boot in BIOS Settings.

Then open Advanced Startup options after the computer boots from USB. Click Repair your computer at the first screen that says Install now.

Select Startup repair, let it finish the job and see if the computer can boot afterward.
If that doesn't help, consider doing a clean install after rescuing your files.
