During the PC health check, secure boot is recommended for Windows 11. However, in BIOS settings, CSM must be disabled for it to work. If you disable CSM in BIOS but Windows 10 still doesn't boot correctly and jumps straight back to BIOS, you may need to adjust BIOS options or consult the manufacturer's support for further troubleshooting steps.

Think about updating to a fresh Windows version, making sure the BIOS settings are properly configured first.

I've had this problem before, where turning on secure boot caused my system to not be able to boot. If I recall correctly, it was because my boot drive was not set up with the GPT partition table. There's a command in Windows to convert your MBR to GPT table. I don't remember which I used, but it should be possible to do without data loss. Pretty sure it was mbr2gpt. Edit: This tutorial seems familiar to me. It seems to do what I did back then, at least.

This document explains that your operating system's drive is divided into MBR and requires partitioning in GPT. It references a Windows command to perform this conversion.

The standard DiskPart instructions appear to create a fresh partition table, which can cause data loss. I recall a method that avoids this issue. I’ve revised my note—there’s a command for converting disks with data retention.

They also reference MBR2GPT.exe, and clicking the link indicates the tutorial suggests using that .exe for conversion. Either method is acceptable.

I completely missed that, I was just trying to go back through what happened earlier.

It's simple to miss. The dense blocks of text from Microsoft are longer and more extensive than a Chinese wall.
