secure boot & tpm 2.0 not detected

Here’s a structured “Quick Scoop”-style post around the topic “secure boot & tpm 2.0 not detected”, based on recent public forum discussions and official guidance.

Secure Boot & TPM 2.0 Not Detected

(Why it happens, what people are trying, and what usually fixes it)

What This Topic Is About

Many users are seeing messages like “Secure Boot not detected” or “TPM 2.0 not detected/supported” when trying to:

  • Install or upgrade to Windows 11
  • Meet game anti-cheat or DRM requirements
  • Pass corporate/Intune security compliance checks

Public forum threads show a mix of confusion, partial fixes, and a lot of “it’s on in BIOS but Windows says it’s not.”

Mini-Section: The Core Problem

“I enabled Secure Boot and TPM in BIOS, but Windows/installer/PC Health Check still says they’re not detected.”

This shows up in several flavors:

  • Secure Boot enabled in BIOS, but tools still claim it’s off.
  • TPM 2.0 enabled in BIOS, buttpm.msc or security apps say ‘not found’.
  • Older gaming PCs (around 2016–2018) where the hardware genuinely lacks Secure Boot or TPM 2.0 support.

In some cases it’s just a setting or OS-detection glitch; in others the hardware simply doesn’t support what modern Windows or games want.

Mini-Section: Common Real-World Causes

From recent tech support and build/PC forums, the causes people keep running into include:

  • TPM is disabled or hidden in BIOS/UEFI.
    • Many boards ship with firmware TPM (fTPM/PTT) set to “Disabled” or “Hidden” by default.
  • Using the wrong place to check in Windows.
    • Users discover TPM is present only after running tpm.msc or checking “Security Devices → Trusted Platform Module 2.0” in Device Manager.
  • TPM device error in Windows.
    • One user found TPM 2.0 present but with a Device Manager error code 19 ; uninstalling the device and rebooting made TPM 2.0 show as detected again.
  • Secure Boot needs UEFI and GPT, not legacy/MBR.
    • A commenter points out that Secure Boot won’t work if the boot drive uses MBR instead of GPT, even if the BIOS option appears.
  • Old or unsupported hardware.
    • A 7‑year‑old gaming PC (built around 2018) was found to have no Secure Boot support at all, and the user is told the system may simply be too dated for strict Windows 11 requirements.
  • TPM 2.0 present but hidden from Windows.
    • Microsoft’s troubleshooting notes mention firmware/UEFI that hides TPM from the OS or isn’t fully compliant, leading to “not detected” even though a chip exists.

Mini-Section: Typical Fixes People Report

Forums show a recurring set of “this finally fixed it” steps.

  1. Confirm support first (motherboard + CPU).
    • Users are often told to look up their motherboard model online to verify Secure Boot and TPM 2.0 support.
  1. Enable TPM in BIOS/UEFI.
    • Names vary: fTPM (AMD), PTT (Intel), or simply “TPM” under Security.
  1. Enable Secure Boot and ensure UEFI + GPT.
    • Check that boot mode is UEFI and that the drive is GPT; one commenter stresses this as a prerequisite for Secure Boot to actually function.
  1. Use Windows tools to verify.
    • tpm.msc via Win + R to confirm presence and version of TPM 2.0.
 * On Linux, a user checked Secure Boot via `mokutil --sb-state` and TPM via the TPM device description path to prove both were active.
  1. Clear or reinstall the TPM device.
    • One user opened tpm.msc or Device Manager, cleared/uninstalled the TPM device, then rebooted; TPM 2.0 reappeared and passed Windows 11 checks.
  1. Update BIOS/UEFI firmware.
    • In some threads, updating the BIOS is paired with enabling TPM and Secure Boot before anticheat or Windows finally stops complaining.
  1. If unsupported, either upgrade hardware or bypass requirements.
    • One commenter mentions it’s still possible today to bypass some Windows 11 requirements, although future feature updates may become more restrictive.

Mini-Section: How This Connects to Latest News & Trends

  • Windows 11 tightening requirements.
    • With Windows 11 24H2 and later, Microsoft is enforcing hardware checks more strictly; content creators now share guides on bypassing TPM 2.0 and Secure Boot checks for unsupported PCs.
  • Security and compliance pressure.
    • In enterprise environments, Secure Boot and TPM status affect compliance rules (e.g., Intune custom compliance scripts that check Secure Boot via PowerShell).
  • Gaming & anti-cheat.
    • Some new games and anti-cheat systems rely on TPM and Secure Boot for integrity checks, so “not detected” isn’t just a Windows upgrade annoyance—it can block certain titles from running.

All this makes “secure boot & tpm 2.0 not detected” a repeatedly resurfacing issue whenever a new Windows feature update or big game launch raises minimum requirements.

Mini-Section: Different Viewpoints People Express

From reading through public discussions, you see a few distinct attitudes:

  • Security-first view.
    • Some users and admins insist on properly enabling and troubleshooting TPM/Secure Boot because they want hardware-backed security and compliance, not workarounds.
  • Pragmatic/bypass view.
    • Others are fine bypassing requirements entirely to keep using older but still fast hardware; they point out that unsupported installs can still receive security updates (with some caveats on feature upgrades).
  • Upgrade-now view.
    • A subset argues that if your PC can’t support TPM 2.0 and Secure Boot in 2026, it may be time for a new motherboard/CPU combo rather than wrestling with hacks.
  • Frustrated/overwhelmed users.
    • Many posters admit they don’t know where to find motherboard models, what fTPM/PTT means, or how to convert MBR to GPT, and they rely heavily on step-by-step community advice.

Practical Takeaway for Someone Facing This

If you or a forum poster runs into “Secure Boot & TPM 2.0 not detected” today, public guidance suggests:

  • First verify your motherboard actually supports Secure Boot and TPM 2.0.
  • In BIOS/UEFI, enable UEFI boot, Secure Boot, and firmware TPM (fTPM/PTT).
  • Check Windows via tpm.msc and Device Manager, and fix any TPM device errors (uninstall/reboot, or clear TPM with proper precautions).
  • Ensure your boot drive is GPT , not MBR, so Secure Boot can truly function.
  • If the system is simply too old, you’ll likely be choosing between hardware upgrades and unsupported/bypass installs going forward.
