[NAME] - You're making this way too complicated... At first, my XPS 8930 didn't qualify for Win 11 either and TPM was grayed out in BIOS setup. I opened BIOS setup and disabled Legacy Options ROM, which I previously enabled, saved the change and exited setup. I rebooted again and went back into BIOS setup. Now TPM is enabled (I didn't even have to change it). So all that was left was to re-enable Secure Boot, save that change and exit setup. My PC now passes both Microsoft's PC Health test and WhyNotWin11. [IMAGE] NOTE: If Win 10 was installed with Legacy Options ROM enabled, it won't boot after you change this setting. By default, Dell installs Win 10 with that option disabled, so you shouldn't have a problem. That said, always better to image the boot drive before making these BIOS changes, to be safe.
Ever since M$ came out with the Win 11 requirements, I have been trying to understand what I have to do to my XPS 8930 to install Win 11 when it's released.  My PC is 3 years old and qualifies for everything except secure boot and TMP. I have read that all I have to do is go into the bios and change these settings to enable. Yet there are just as many instructions that have a 3-page list of all things that have to be done to enable these things.  When I try to enable secure boot, I get the message I can't do that with "UEFI with Legacy OPROM" enabled. I thought I was already using UEFI. That shows up in System Information. I thought that every time I installed the next version Win 10 (Clean Install) I always chose  UEFI. I never paid much attention, because everything worked fine. Are there any easy-to-follow, fail-proof instructions to resolve this, so I can use Win 11 down the road? Thanks.
