Hi Theerawat

My name is Andre Da Costa; an Independent Consultant, Windows Insider MVP and Windows & Devices for IT MVP. I'm here to help you with your problem.

Option 1

Go to another working computer, download then install Macrium Reflect Free and create bootable Rescue Flash Drive.

Boot from it and click on 'fix windows boot problems'

Make sure bios is set to uefi or legacy bios depending on how it was installed.

See instructions how to download it:

See the section: Create Rescue Media

Option 2

	First of all, if you have any non-essential hardware attached to your computer apart from mouse and keyboard, disconnect them.

See if the system boots successfully, if it does not, carry out the following steps

Power on and off your computer three times

How do you do that?

Power on, when you see the Windows Logo - power off

Power on, when you see the Windows Logo - power off

Power on, it will then your computer will boot into the Advanced Recovery environment

You might be asked to sign in with your Microsoft Account or Local Account password.

**********************************************

Click Advanced Options

Click Troubleshoot

Click Advanced Options

Click System Restore, see if you can go back to an earlier time.

If not, boot into the recovery environment again, then try performing a startup repair.

Perform the startup repair a couple more times then restart again to see if you are able to boot to the desktop successfully.

If that does not work, boot into the recovery environment, then click 'Go back to previous version of Windows' - choose this option if you recently upgraded to a new Windows 10 Feature Update. If this option is not available, you can skip this step.

Option 3

If that does not work.

Power on and off your computer three times

On the third time, your computer will boot into the Advanced Recovery environment

Click Advanced Options

Click Troubleshoot

Click Reset this PC

Click Keep my files

Choose your account

Enter your password

Click Continue

Click Reset

Option 4

If that does not work.

Go to a working computer, download, create a bootable copy, then perform a clean install.

Hi,

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.

https://www.tenforums.com/tutorials/21756-boot-...
https://www.tenforums.com/tutorials/21284-enabl...

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.

Hi Theerawat

Start your PC, just as Windows attempts to load (spinning dots), press and hold Power Button for 5 - 10 seconds to perform a Hard Shut Down

Do this twice

On the third start Windows will boot into the Recovery Environment and from there you can access System Repair, Safe Mode, Command Prompt . . . etc.

Please try each option one at a time, then see of Windows will boot . . .

Go to Troubleshoot - Advanced Option - System Restore

Check to see if you have a restore point you can go back to

If you do not have a Restore Point, go to Troubleshoot - Advanced Option - Startup Settings and click Restart

Upon restart, press 4 to enter Safe Mode

Once in Safe Mode, backup your data if you do not already have a backup

Open Device Manager and check to make sure all your Drivers are up to date

Reboot to see if Windows will start Normally

If the above fails, go to Troubleshoot - Advanced Options - Reset this PC

Choose to keep your files and apps, just your files or to keep nothing

Then start the Reset
