Hey, I could use some help to be honest.

I build my PC with help 7 years ago, wanna update from Windows 10 Pro to 11 since they’ll be discontinuing updates for it. The processor is supported (Intel core i5-8600K CPU @ 3.80GHz), 8GB Ram, system storage 240GB, processor 6 cores, that’s all good. The requirements not met are the Secure Boot and TPM 2.0 not detected. In simple terms, can I solve this myself? Would really appreciate a straightforward guideline.

    Thank you for the screenshot, that is what I suspected.

    Windows 10 is installed in Legacy BIOS mode, and to enable Secure Boot and TPM you need to change BIOS Mode to UEFI Mode.

    However, you cannot do that directly, because your drive has an MBR partition style, and for UEFI Mode, it needs to be have a GPT partition style.

    It is a big job to convert convert your drive to GPT, there are two methods.

    1

    Backup your personal files, then clean install Windows 10 form a bootable USB and before doing that you will need to change BIOS to UEFI and convert the drive form MBR to GPT, which would wipe all data on the drive.

    2

    You can try to convert the drive without data loss from MBR to GPT using the tool that Microsoft provide, then boot into BIOS and switch to UEFI Mode

    Before you attempt to do this, please backup your personal files.

    This is most likely caused by the way Windows 10 was installed, I need to check your system, click your Start Button, then just type msinfo and press Enter, please provide a screenshot of the resulting System Information window.
