[SOLVED] Windows 11 Second Boot Error KMODE_EXCEPTION_NOT_HANDLED

[Danovic]

Hello,
i am trying for a few weeks now to upgrade from Windows 10 to Windows 11, but every time i get the same error (see photo).
The error shows at 64% when the PC reboots for a second time. I tried with Win11 InstallationAssistant and with the ISO file, both show the same error.
If someone managed to solve it, would appreciate. I have already enabled TPM version 2.0 and Secure Boot in bios but.
PC Specs:
i9-10900L
NZXT Kraken X73
Samsung 970 EVO Plus
Seagate IronWolf 4TB
16GB G.Skill Neo
MSI MEG Z490 ACE

After that it restarts and restores to my Windows 10.

if it happens during windows installation (from usb iso), then its hardware incompatibility issue
your bios is up to date? old bios version can affect hardware compatibility aswell
msi bios download page has win 11 support bios 7C71v1B
https://www.msi.com/Motherboard/support/MEG-Z490-ACE#down-bios

you will need to disable TPM first in bios, then reboot to bios to flash it
once done, tpm can be enabled

Hello,
i updated my BIOS seccesfully with the one that you sent me. I didnt tried installing from USB ISO, i tried the Assisstant and i tried PowerISO with virtual drive.
After the bios update i tried those both ways and still the same error.
The only thing that i didnt try was to install it from USB, but is there a difference?

Hello everyone,
i managed to fix the problem. What i did was Factory Reset on my Windows 10, without keeping any files. After that i just updated Windows and downloaded the Assistent for Win11, and this time it was installed without any errors.

I hope this helps someone,

Best Regards
