If this is your only problem, one easier way would be to perform a clean install.
Microsoft warns that you should only do this if you know your PC supports UEFI, and that you may have to change settings in your PC’s firmware to make it boot in UEFI mode rather than legacy BIOS mode afterward. Microsoft’s MBR2GPT tool may allow you to convert a drive from MBR to GPT format.
Modern Linux distributions like Ubuntu and Fedora work on PCs with Secure Boot enabled, so you don’t necessarily have to disable this security feature to install Linux. You may have disabled Secure Boot to install Linux, or it may have come disabled on your motherboard. If PC Health Check reports your computer isn’t using Secure Boot, you should also look in UEFI firmware settings for a “Secure Boot” option and enable it, if possible. You should be able to upgrade normally if that was your only problem. Check with your computer (or motherboard) manufacturer for more information about updates for Windows 11.Īfter enabling TPM, re-run the PC Health Check tool. It may even be possible to upgrade from TPM 1.2 to TPM 2.0 with a firmware update on some PCs it depends on your hardware and system manufacturer. Manufacturers have been rolling out updates that either enable TPM 2.0 by default-or add support for it. You may also need to install a UEFI update for your computer or its motherboard.
(If you built your own PC, search for your motherboard model name instead.) For more information, run on online search for the model name of your computer and “enable TPM,” or examine its official documentation.
