I have been struggling with this on and off for a while now. I know where I need to go to enable intel trusted nonsense, disable the CSM, making sure my bios is up to date, but no matter what I try, once I save my settings Windows refuses to boot completely. It eventually attempts to repair and I have to reboot, rinse and repeat. I try for a few days then give up and say Windows 10 is fine, why bother, and forget about it for months. I know I'm missing something but this post at least gives me hope that I'll figure it out eventually!

Hi Alireza. I'm Greg, 10 years awarded Windows MVP, specializing in Installation, Performance, Troubleshooting and Activation, here to help you.

There's a November 2021 BIOS Update here if yours is not updated:

Then you can read the Manual here to find out how to enable Secure Boot:

If it's still not clear then contact Asus Support to find out how to enable Secure Boot on your BIOS:

You can also ask in Asus forums:

Is Windows presently installed in UEFI mode, as this can make a big difference in Secure Boot showing up? If you're unsure type System Information in Search, open and look for BIOS mode.

If not installed to UEFI I'd consider reinstalling to UEFI either with WIndows 10 doing this gold standard Clean Install which includes everything that works best in Windows 10: http://answers.microsoft.com/en-us/windows/wiki...

or do a Windows 11 Clean Install:

Make sure to create the bootable media using Media Creation Tool only, boot the media as a UEFI device, delete all partitions down to Unallocated Space to clear formatting, then select the Unallocated Space and click Next to let the installer create and format the needed partitions - which makes it foolproof.

Feel free to ask back any questions. If you'll report back results for each step it can help determine what else needs to be tried. I will stick with you until it is fixed.

Secure Boot is a security feature in modern computers that ensures only trusted software (like the operating system or firmware) can load during the boot process.
