If it is compatible and you are still experiencing issues with Windows 11 and cannot install the update, it seems that TPM 2.0 and Secure Boot are missing from the BIOS.
What is TPM 2.0?
TPM is a computer chip that provides hardware-based security. When the BIOS/UEFI and CPU do not fall within Microsoft's allowed range, you cannot install Windows 11. Below is a list of supported AMD and Intel CPUs.
8th generation Intel Core processors and newer products.
AMD Ryzen processors.
Ryzen 3000 series and newer products.
Steps to check TPM 2.0 on your PC
1. Press Windows + R to open the Run window.
2. Type tpm.msc and press Enter.
Type tpm.msc_
3. This will open the TPM Management window. Here, under the Status tab, if you can read TPM is ready for use, it means TPM is enabled. Check the TPM version from the bottom of the TPM manufacturer information.
TPM Management Window - TPM Management
4. If TPM is compatible but disabled, you will see a message saying "Compatible TPM cannot be found." This means you need to log into BIOS to enable it.
To do this, follow these steps.
