I recently tried to upgrade to Windows 11, and the PC Health Check tool indicated I needed to enable Secure Boot. I followed a guide and turned it on in my BIOS settings. Now, when I restart my PC, it goes straight back to the BIOS and isn't detecting any of my drives to boot from. I have a H410M H V2 motherboard and Windows installed on my HDD. Any advice on how to fix this would be greatly appreciated!

Before making any changes, make sure to back up your important data. If you're planning to use MBR2GPT, do so after you've secured your files. Once you run MBR2GPT, you can then switch your system back to UEFI and try booting again. Just remember, the transition can be tricky, so be prepared for any surprises!
It sounds like you might need to switch your boot type from CSM (Legacy) to UEFI. If you do that without making additional changes, your installed OS may become unbootable. Try reverting back to CSM to see if that allows you to boot. Also, definitely back up your important files first, because processes like MBR2GPT can fail and you might end up needing to do a clean install later.
