Windows does not start after enabling secure boot

Solved

Hello, here is my problem.

I installed Windows 11 only with TPM 2.0 enabled.

Today I wanted to play a game called Valorant, but once I launched the game it asked me to enable secure boot.

So I researched how to enable secure boot; after more than an hour, I understood the system and enabled it.

And when secure boot is enabled, I can’t get beyond that:


I am in UEFI and my SSDs are in GPT.
I would like to point out that I reinstalled Windows because I thought it would be impossible to enable secure boot with an already installed Windows.
My BIOS is up to date.
I also tried the technique to "bypass" secure boot.

Yes, I could simply go back to Windows 10 to access Valorant. But I'm a rather stubborn person, so I don't intend to give up and go back to Windows 10.

    Hello,

    If the CSM is active, you are not in UEFI.
    Check if Windows WHQL is also active.

    Thank you for your response.

    My CSM is disabled:


    For Windows WHQL, it is indeed activated because when I try to disable it, I receive this error message:


    Which can apparently be fixed by disabling secure boot, which I do not wish to do.

    I will still test disabling secure boot to disable Windows WHQL in order to reactivate secure boot.

    - secure boot disabled

    - the command "bcdedit /set testsigning on" to disable Windows WHQL was typed in an administrator-open Windows terminal

    - the command worked:


    - I restart my PC to open the BIOS and enable secure boot that I had previously disabled

    - it does not work:

      But what are you starting on? The recovery partition? You need to go back; an upgrade is never 100% safe, you need to reinstall Windows 11, and it may also be possible that your storage is faulty or there is another issue.

      You shouldn't have bypassed in compatibility mode; this can generate other problems, Microsoft has said that, more issues and no security upgrade.

    If I understood correctly, a complete reset would be very beneficial for my problem?

    If so, is there a way for me to back up my data before doing it?

      I'm not talking about a reset but rather a formatting, yes, unless the issue comes from somewhere else, this will fix the problem. To back up your data, you need to use a live USB or put the hard drive in a USB adapter to recover the documents you want from another PC, but everything will need to be reinstalled after formatting: programs, drivers, settings, data, etc...

      If you want to avoid losing data, and if there's enough space on the disk, you can install Windows on the same partition again; the old Windows will be under a folder named windows.old, from which you can recover what you need.

      Think about it carefully, and do your research before anything else.

    Problem solved :)

    I formatted my drive with the Windows tool to put the Windows 11 ISO on it.

    I then reset my PC to factory settings by erasing all my files.

    I kept secure boot enabled while installing Windows 11 and it worked.

    Secure boot is indeed enabled without causing me any issues:
