Hi Alvin, I am John J.D., a fellow Microsoft user like you.
I understand you're having issues with your computer and now troubleshooting using Windows Recovery Environment. I'm here to help.
Please try using Bootrec.exe commands via the Command Prompt in the Windows Recovery Environment.
- Hold down the power button for 10 seconds to power off your device.
- Press the power button to turn on your device. As soon as you see the initial indication of Windows starting (such as the manufacturer's logo appearing during a restart), hold down the power button for 10 seconds to power off your device.
- Repeat this process twice.
- On the third start, Windows will boot into the Recovery Environment.
- Select "Advanced options."
- On the "Choose an option" screen, choose "Troubleshoot" and select "Advanced options".
In Advance options, click "Command Prompt"
In Command Prompt window type this command and press Enter:
sfc /scannow
(note the space between "sfc" and "/") and press Enter. Wait for the scan to complete to 100%. Next commands are for Bootrec.exe, type this commands and press Enter:
bootrec /fixmbr
(note the space between "bootrec" and "/") and press Enter. The message should be "The operation is completed successfully". Next, type this command and press Enter:
bootrec /fixboot
(note the space between "bootrec" and "/"). If you get "Access Denied", please type this command:
bootsect/nt60 sys
Once completed, type this command again: bootrec /fixboot
Lastly, type this command and press Enter:
bootrec /rebuildbcd
After that, type "Exit" and press Enter.
Then click "Continue" to exit and continue to Windows.
Please let me know how it goes.
John J.D.
