I have a Windows 11 25H2 machine Gigabyte X470 gaming wifi7 that worked fine (with secure boot and fTMP enabled).

Had No problems so far since windows 11 was installed on my pc (1 year approx)Before yesterday new windows updates. The next morning during start of the pc I see the blue screen winload.efi 0xc00000e9 appearing. I could only get a startup to windows 11 after setting fTMP disabled in the bios.

So, UEFI mode Secure boot enabled and TMP disabled is the only setting in the bios that i can boot to windows 11.

What happend?

    Most likely, there was a firmware update installed on your PC with the update, go to the support page for your PC on the manufacturers website to check if there is any BIOS update available that may need to be installed.

    2

    If that does not resolve the problem, boot your system into BIOS, find the TPM settings, and there should be an option to reset TPM keys to factory keys, before doing that, it is best to backup your files to ensure against data loss.

    Windows bootmanager is the first in the boot order

    Going to Recovery Environment after 2 times interrupting does not work on my pc

    Blue screen is always first.

    There was a bios update available from 14-04-2026 and I flashed my bios with this update but no result

    I made a USB stick with Windows 11 recovery environment on it.

    Booting with this stick gave the same blue screen

    I think the best option may be to contact Gigabyte support, there may be some other setting in your BIOS that needs to be enabled or changed, if not, if resetting TPM keys and Secure Boot keys does not resolve the problem, you may need to backup your files and clean install Windows with TPM enabled in BIOS
