TPM not found during BIOS setup following a factory reset of Secure Boot.
TPM not found during BIOS setup following a factory reset of Secure Boot.
Hi everyone, I've searched extensively online and decided to reach out for assistance. I'm not very experienced with TPM yet, so I explored the settings to perform a clean upgrade to Windows 11. I have a Windows 10 key and wanted a fresh installation instead of an upgrade. On my Acer Nitro 515-52 laptop, I set a supervisor password in the BIOS to allow edits to Secure Boot. After pressing enter, I tried these actions: - Delete all Secure Boot settings - Restore Secure Boot to factory defaults - Wipe TPM Then the following options vanished: - Current TPM state - Change TPM state - Clear TPM Now even with Secure Boot enabled in BIOS, the Windows 11 installer couldn't start. The system also failed to recognize the previous TPM 2.0 I had before. I checked tpm.msc using Windows+R and confirmed TPM is missing. Could my recent changes have removed TPM completely, preventing the installation of Windows 11? I'm really confused and stuck.
The Trusted Platform Module (TPM) serves as a secure place to store sensitive data such as private keys. Removing it would erase any information it holds at that moment. For example, disks encrypted with a private key stored in the TPM would become unrecoverable. This action shouldn't be taken if you're using the data right now. I saw another source suggesting you must disable secure boot, reinitialize the TPM, and use default UEFI keys afterward. Likely it also holds trusted secure boot certificates that are no longer valid.
You appreciated the extra details. I restored Windows 10, toggled Secure Boot several times, and the TPM feature reappeared. Correct in turning it off and back on. Thanks!
