Hi to All, I have 3 older HP elite desktop computers with legacy Bios, and TPM 1.2 installed. I have been researching Win 11 installing. It seems that there are many ways to bypass some of the issues with the install. I can't seem to find specific instructions to bypass the installation issues for my machines. Some of these instructions are bleak and others want to bypass everything. Knowing that I have TPM 1.2, I am trying to get past "secure boot and the unsupported Core 2 CPUs". I have Windows 10 pro on all of them. I have picked up WinBootMate. I'm just not sure if it will give me the final results needed for an install of Win 11. Any advice would be appreciated.
Thanks

The easiest method is to just use the Rufus utility to create the bootable flash media. It has the options to bypass all the Win11 requirements.

    I'm a computer enthusiast so have quite a few systems that I run. More like an advanced hobby.
I upgraded 2 Notebooks [1 Home and 1 Pro from 2014] to Win11 but not by booting to Win11. I used the MCT process to create the bootable USB Thumb drive [8GB or larger] and while booted into Win10 I made the [publicized] single-file change on the USB drive and ran setup.exe from it. They have passed the last 2 Patch Tuesday updates without issue.

Thanks very much, I installed as advised and it worked out well. I backed up my existing hard drive and installed Win 11 from Rufus. All updates ran as expected and very I'm happy with the results.
Thanks again

Is the BIOS updated to the latest version?
It shouldn't make any difference, but it sure improves stability and performance if you upgrade to the latest BIOS combined with installing all the latest drivers.

    Legacy MBR installation, no TPM, no Secure Boot, no WDDM 2.0 graphics drivers, cannot get more unsupported ;) This is only my test laptop. I had installed Windows 11 here before upgrading my main PC. For my main PC I use everyday see my 2nd system specs.
