    BIOS mode as Legacy or UEFI?


    My Windows 10 says its BIOS mode is Legacy with C drive partition as MBR. Is it worth switching to UEFI mode with C drive as GPT partition? Why does it seem so difficult to install to UEFI mode with GPT partition? You do not get an option to choose when you install windows 10 on a clean disk with Windows 10 USB installer tool. I never really thought of this when installing windows 10. I thought it would automatically go UEFI. Do most people not care about this?

    It is also annoying that Window's 10 backup create image does not work and I think it is related to your BIOS mode and partition. I can't install a backup image of my current windows 10 without getting an error message.

    :)

    Problem Regarding Bios Change from UEFI to Legacy

    I have hp pavilion p045tx with windows 10 pro. I recently install Ubuntu with windows 10 so for that I convert my bios setting from UEFI to Legacy mode for install third party software like wireless Driver and all in Ubuntu.
    But after every restart the bios setting change to default and that is to UEFI mode and that will cause an problem of no OS detect. Every time I have to go to bios setting and enable the legacy mode to start my OS. Can anyone suggest me what to do in this
    case.

    Legacy to UEFI

    I'm debating moving to UEFI form my now legacy BIOS (Award Software Int.) the mother board is a GA-Z68XP-UD3 rev1.0 on the the following link it shows a UEFI BIOS U1J )UEFI BIOS)

    GA-Z68XP-UD3 (rev. 1.0) | Motherboard - GIGABYTE Global

    Currently I'm running the legacy F10 BIOS. Does installing the UEFI BIOS automatically take care of everything to get to the UEFI BIOS? Installing the UEFI BIOS following the instructions using the Q-flash method GIGABYTE How to Reflash Motherboard BIOS

    What's steps do I take and in what order?

    Much appreciated

  4. BIOS mode as Legacy or UEFI?

    Unable to upgrade to Windows 10, Error message: A system image created using UEFI cannot be restored on a computer using legacy BIOS.

    Hi,



    UEFI BIOS supports two boot modes: Legacy BIOS boot mode and UEFI boot mode. Some devices and operating systems do not yet support UEFI-based BIOS and can boot only from Legacy BIOS boot mode. Choose Legacy BIOS boot mode to allow HBAs and Express
    Module devices to use option ROMs. Choose UEFI boot mode to use UEFI drivers.



    Only devices that support the selected boot mode are listed on the BIOS Boot screen. If you select UEFI Boot Mode, only boot candidates that support UEFI BIOS boot mode are listed on the BIOS Setup Utility screens in the Boot Options Priority list.
    If you select Legacy BIOS boot mode, only boot candidates that support Legacy BIOS boot mode are listed in the Boot Options Priority list.



    Please refer to the below article to Upgrade to Windows 10 using ISO File.
