    My PC has Tough Gaming and Intel’s PTT.

    Can this be activated and accepted by MS to substitute for its TPM to run, w/o complications, when Win 11 is installed?

      Bypassing Windows 11 hardware requirements, revisited – Out of Office Hours (oofhours.com)

      So let’s summarize. If you set these HKLM\System\Setup\LabConfig registry values, you can bypass some of the hardware checks:

      • BypassRAMCheck = 1. This works fine to enable SETUP.EXE to install Windows 11 on a machine with less than 4GB (well, really 3686MB) of RAM.
      • BypassTPMCheck = 1. This works fine to enable SETUP.EXE to install Windows 11 on a machine that doesn’t support TPM 2.0.
      • BypassSecureBootCheck = 1. This one is really somewhat misnamed as it doesn’t really do anything on UEFI systems. It does allow SETUP.EXE to install Windows 11 on BIOS-based machines that can’t possibly support SecureBoot (since that’s a UEFI feature).

      See if that will work?

      … BIOS-based machines that can’t possibly support SecureBoot (since that’s a UEFI feature).

      Not quite–apparently SYSLINUX has an UEFI emulator (DUET) which can call the standard Windows UEFI bootloader – bootx64.efi.
      See Booting Windows 7 / 10 from GPT Disk on BIOS (non-UEFI) systems.

      Now why would I have stumbled on this?

      I blithely got a Seagate 4TB hard drive recently. Come to find when Windows 10 installed on the drive in my BIOS based system it only partitioned it to use 2TiB of the space available. The remaining 1.68TB was inaccessible unless I converted the drive from MBR to GPT using MBR2GPT. Trouble is that Windows won’t boot a system partition on that GPT drive unless UEFI is used.

      I found if I booted a system partition on a MBR drive I could choose to run Windows 10 as installed in the partition on that 4TB GPT drive. There are a lot ways to do that without having to have a second hard drive:

      1. A flash drive can be used.
      2. GRUB 2 can be used
      3. Use SYSLINUX’s UEFI emulator (DUET)
      4. Use CloverEFI UEFI firmware emulation which is based on (DUET)

      However I came across a far simpler solution printed on older Seagate drive labels shown on ebay.com, “www.seagate.com/beyond-2TB”. This takes you to Getting the most from your hard drive larger than 2TB. The solution is called DiscWizard Extended Capacity Manager Software. Basicly I switched the drive back to MBR and then used the DiscWizard which creates another 1.68TB disk as far as Windows Disk Management is concerned. My problem was solved.

      BTW, MBR2GPT does not erase the data on the disk. It only shrinks the Windows partition to make room for a 100MB UEFI FAT32 partition and writes the GPT backup in the last thirty-three 512 byte sectors of the drive. The GPT is in sectors 1-33 at the beginning of the disk:
      Sector 0 containing the MBR boot code and is zeroed and a protective partition table is installed.
      Sector 1 and last# contains the GPT header
      Sector 2 and last#-32 contain the info for the first 4 partitions
      Sectors 3-33 and last#-31 thru last#-1 contain the info for partitions 5 thru 128 which are all zeroed out when not used.
      Restoring sector 0 and zeroing sector 2 is sufficient to convert from GPT back to MBR and vise versa provided that those 4 partitions remain within the 2TiB limit.

      My PC has Tough Gaming and Intel’s PTT.

      Can this be activated and accepted by MS to substitute for its TPM to run, w/o complications, when Win 11 is installed?

      Yes:

      To your operating system and applications, PTT looks and acts exactly like TPM.

      These firmware TPM solutions also meet Microsoft’s Windows 11 requirements. This means that systems with Intel PTT or AMD’s fTPM solution should be in the clear for Windows 11 support.

      TPM 2.0 for Windows 11 – What is it and what about Intel PTT and AMD fTPM?

      The option to enable the TPM may be labeled Security Device, Security Device Support, TPM State, AMD fTPM switch, AMD PSP fTPM, Intel PTT, or Intel Platform Trust Technology.

      You can check Win 11 compatibility by running the portable WhyNotWin11 app.

      TMP isn’t enough. You need Secure Boot, Intel CPU 8 gen+, ..
