        Does my PC needs to be UEFI to be able to run Win 10 20H2 ?

        Mine is Legacy Bios and I am on Win 10 1909.

        If you already running W10 I’m sure you can update to 20H2.

        To check UEFI status, Win R, msinfo32
        In the right pane, look for “BIOS Mode”. (Mine says UEFI)

        cheers, Paul

        To my knowledge, there is only one hard-and-fast rule regarding Windows and UEFI.

        Microsoft mandates Secure Boot to OEM’s, which is not available with older BIOS/MBR systems because the firmware is not up to the task (Trusted Platform Module on the motherboard), and so requires UEFI/GPT.

        Windows will readily install/upgrade on BIOS/MBR systems.

        Create a fresh drive image before making system changes/Windows updates, in case you need to start over!

        no.

        Win10 20H2 can run on either legacy BIOS or UEFI systems

        I have Win10 20H2 Pro running on a custom built PC using a Gigabyte GA-78LMT-USB3 R2 motherboard which uses legacy Award BIOS (non-UEFI)
