Unable to enable Secure boot for Asus strix X470 I gaming

[HotPeaSoup]

I am attempting to install win 11 on my fairly modern PC, but I am unable to satisfy PC health check. It thinks my Secure boot is disabled. Even Unsupported. I have updated my bios to the latest version and have tried to find any BIOS settings

that should have any effect. But no success. Does anybody have any idea what's the issue or what are the correct settings. Sys info lists BIOS mode as legacy ( i haven't figured out how to change that) and Secure boot as unsupported.

Check out the video I found on YouTube.  I believe it will answer your questions.

Unfortunately it does not help.

I the video he has more options. He has a Platform key state.

 

For me it just says "Enabled" as if all is good. I have tried installing and removing the keys.

 

 

But the health check still complains!

I figured it out.

Actually I had installed my windows 10 in Legacy BIOS mode. It is not the same as having the BIOS set to UEFI. Although If your windows is installed in UEFI mode, then the BIOS has to be in UEFI mode aswell for the PC to boot successfully.

 

Anyways it is possible to convert your windows installation to UEFI without reinstalling Windows. There is a tool for this  "Windows\System32\MBR2GPT.EXE". It converts a disk from the Master Boot Record (MBR) to the GUID Partition Table (GPT) partition style without modifying or deleting data on the disk.

 

To convert my disk I opened the Console as administrator and typed in two commands.

"mbr2gpt /validate /allowFullOS" This just validated that it works

"mbr2gpt /convert /allowFullOS" This converted my disk.

Now I have a "BIOS mode UEFI" windows installation and the secure boot feature is ON. Also the PC health check sais that my PC meets windows 11 requirements.

 

Yay.

I tried that but I keep getting "Invalid Arguments."

[HotPeaSoup]

From what I understand "Invalid arguments" generally just means that you have typed something wrong.
*Did you remove the quotation marks from the commands? ("") They need to be removed.
*Did you leave the spaces before the forward slashes. They need to stay there.

*Although I believe you followed my previous suggestion, just make sure you run CMD as administrator.
