Since now I have two Windows installations, I got to see the Windows Boot Manager/BCD entries. Intel Bluetooth driver not available (AC 7260). Virtually all drivers just installed fine with an available version from Windows 10. No TPM secure boot disabled during installation (can be enabled) The latest available driver from 2020 (10.) installs fine and works. GPU: HD 4000 (not compatible with WDDM 2.0)- By default, this driver from 2015 was installed: 10. There should have been quite a number of instructions on Reddit as well.ĬPU: Core i5-3340M (dual-core, 4 threads) For some reason webpage, links are blocked by Reddit. Regarding how to do the registry trick, please google 'windows 11 bypass tpm regedit'. I ended up using the iso here: (huge thanks!) and fresh-installed on a spare drive, and it worked after the registry trick. Running the setup from the iso inside this Windows 10 install did not work either. Upgrading from Windows Update failed due to the lack of TPM and the age of the CPU -I tried both the registry trick and replacing the dll but neither worked (ended up having error 0xc0000005). This machine was running the latest Windows 10 insider preview (dev). I've managed to install the build 22000 released today on an old HP laptop (updated to 22000.51).
