Windows 10: When I enable Secure Boot in the BIOS, save the settings, and reboot my PC it goes into a loop

When I enable Secure Boot in the BIOS, save the settings, and reboot my PC, it goes into a loop where it attempts automatic repair, diagnosis, and rebooting. Despite selecting options like 'Restart' or 'Advanced Options,' the issue persists. However, disabling Secure Boot in the BIOS resolves the problem, allowing the system to boot successfully.

Enable Secure Boot B550M DS3H AC

Hello Jose Luis Beltran Adame

Welcome to the Microsoft Community.

Can you tell me your motherboard model? Click Search on the taskbar and enter Device Manager.

To enable Secure Boot on your Gigabyte B550M DS3H AC motherboard, follow these steps:

1. Enter BIOS Setup:
   
   Restart your computer and press the Del key (or the key specified for your motherboard) repeatedly as soon as the system starts to boot, to enter the BIOS setup.
   
2. Navigate to the Boot Menu:
   
   Once in the BIOS, use the arrow keys to navigate. Look for a tab or section named Boot, Security, or something similar.
   
3. Enable Secure Boot:
   
   1. Inside the Boot or Security menu, find the Secure Boot option. It might be under a submenu, often labeled as Windows OS Configuration, Boot Mode Selection, or similar.
      
   2. Change the Secure Boot setting from Disabled to Enabled.
      
4. Change Boot Mode if Necessary:
   
   Make sure that the Boot Mode is set to UEFI and not Legacy or CSM (Compatibility Support Module). Secure Boot requires UEFI mode to be enabled.
   
5. Save and Exit:
   
   Save the changes and exit the BIOS. This is usually done by pressing the F10 key and selecting Yes to save the configuration and restart the computer.

If you cannot find the Secure Boot option, ensure that you have the latest firmware/BIOS version for your motherboard. Manufacturers sometimes update the BIOS to improve compatibility and add new features. You can check Gigabyte's official website for the latest BIOS version and instructions on how to update it.

In case the Secure Boot option still doesn't appear, it might be hidden or disabled due to another setting in the BIOS, such as a legacy boot mode or CSM compatibility mode being enabled. Make sure these are set correctly or disabled to allow Secure Boot to be enabled.

If you continue to face difficulties, consulting the motherboard's manual can provide more specific guidance, or contacting Gigabyte's support for assistance might be necessary.

Disabling CSM and enabling secure boot makes my Boot drive disappear.

Windows 11 upgrade requires I enable secure boot on my PC, it's main use is as a home Plex Server, It has an Intel 8700k and I just use the integrated graphics UHD 630, I don't need a discreet gpu for this. I believe W11 supports this.

In the BIOS (gigabyte z370 motherboard) the Storage Boot Option & Other PCI Devices are set to UEFI mode.

To enable 'Secure Boot' I have to disable CSM support, which I do and enable secure boot but when my PC reboots it goes back to set up and there is no boot drives listed, I have to return the bios back to the original for my drives to show up, the Boot drive is a nvme Samsung 980 pro.

Can anyone tell me what I am doing wrong?

Thx.

 

HP Laptop Boot Loop

I am encountering a boot loop problem with my HP laptop. Upon startup, it shows the HP logo and loading dots for about 11 seconds, then goes to a blank screen for approximately a minute before automatically restarting. The power button does not turn off during this cycle.

Troubleshooting Steps Taken:

• Tried hard reset and accessing BIOS/UEFI settings.
  
• Unable to boot into Safe Mode or recovery environment.
  

please see here the recorded video demonstrating the boot loop behavior for reference.

Any advice, troubleshooting steps, or insights into what might be causing this problem would be greatly appreciated.

Thank you in advance for your help and suggestions.
