I had a lot of RED the first time around and now I'm mostly GREEN due to one particular topic that causes all the RED. This was a rabbit hole that took a while to chase down......

I had RED items with Boot Method, Disk Partition Type, & Secure Boot.

So you have to convert your OS disk, typically C:\ from MBR (Master Boot Record) to GPT (GUID Partition Table). When that's done you can switch your BIOS from Legacy to UEFI. Once that's done, you can turn on Secure Boot in your BIOS.

If your computer is too old, BIOS may not even have an option for UEFI. I had the option but it didn't work at first because the OS disk wasn't converted.

Convert MBR to GPT with MBR2GPT Tool in Windows 10 V1703 or Later

Once I hit that link I followed the "How to convert MBR to GPT with MBR2GPT?" part of the page for running in Windows 10. One thing of note when running the command, your C:\ OS drive may not be zero unless it's your only drive. Since I have extra drives on my main PC, my OS drive was actually Disk2 per Disk Management. So I put a 2 in the command where "N" was and it ran fine.

From there, I just had to reboot the PC and press F2 to enter BIOS. I switched from Legacy to UEFI and then turned on Secure Boot and now I have the result below:
