I'm facing issues upgrading to Windows 11 due to the requirements for TPM 2.0 and Secure Boot. I've tried enabling TPM without any problems, but when I attempt to enable Secure Boot, my PC fails to boot past the BIOS stage. It seems like the system can't find the boot drive. I've followed various online guides to adjust the necessary BIOS settings, including switching from Legacy/UEFI to UEFI and changing CSM to UEFI. I even enabled Secure Boot in custom mode, which prompted me about PK Keys, although I'm not totally clear on that after some research. After making these changes, I couldn't get past BIOS, and the only way I could resume normal use was by reverting to my old Legacy/UEFI BIOS. I'm pretty sure I followed the correct steps, but I'm not very experienced with BIOS adjustments. Could my storage partitions be the issue, or do I need to update something else? I can see my Windows drive in the current BIOS, but it disappears under the new settings. Any advice would be appreciated; I'm really stumped!

Just a heads up, making changes to your BIOS or disk setups can potentially lead to data loss. It's super important to back up your data before making any major changes. If you haven't done this yet, it'd be wise to sort out a backup plan before trying to move to UEFI and Secure Boot.
It sounds like you're running into typical issues that happen when switching from Legacy BIOS to UEFI. UEFI requires your drive to be formatted as GPT instead of MBR, and if your OS was installed with MBR, switching could leave you without a bootable drive. You might want to look into using Microsoft's tool for converting MBR to GPT. If you can do that successfully, you should be in a better place to enable Secure Boot and move forward with Windows 11.
