Windows 10: MBR or GPT

Discus and support MBR or GPT in Windows 10 Installation and Upgrade to solve the problem; [img] where do I find this, set your BIOS for UEFI.

  2. Disable CSM

    Boot device: UEFI only (I think)
    I'm not sure what the Optional ROM is on that board

    I'm not sure about Secure Boot - some say disable it for the install and others say that's not necessary.
    My best guess - disable it for the install, enable it afterwards.

    This is just not true. The decision to create a uefi gpt disk or legacy bios mbr disk depends on bios

    Some are legacy bios only older machines.

    Mjority are both usually bios selected.

    Some are uefi only (newer devices)

    Windows 8/10 does not require secure boot to be disabled - indeed you should leave it enabled really.

  6. I think so, but you should wait for other members to confirm.

    While you wait, review the Clean install tutorial in post# 10

  7. I don't have a dog in this race, so I'm leaving it up to other members and debgram.

    As I said, some say disable it for the install and others say that's not necessary

    You fall into the latter category *Wink

    I'm not saying that you're wrong, I trust the tutorials for best results

    Warning Before you get started installing Windows 10, be sure that you temporarily disable Secure Boot and Fast Boot in your UEFI firmware settings until finished. Some motherboards do not support booting from a USB flash drive with these enabled.

    Once installation has finished, you can enable Secure Boot and Fast Boot again if you like.
    I'm bowing out and will watch from the sideline, don't have more to add.

    Best of luck debgram - there are good members posting in your thread that can help you more than I can.

    Hi there

    you need to DISABLE SECURE BOOT (not UEFI of course) since the SECURE BOOT prevents you from booting alternative OS'es such as Linux or bootable recovery media such as a bootable Free Macrium from a USB.

    It will probably prompt you for a key --just hit enter. (This key is the secure boot key - not windows but usually hitting enter is enough). If it insists on a key then in your BIOS menu there will be some option to display it. Take the key down on a piece of paper (in the age of phones - can people even WRITE any more !!!) and then enter that number.

    You can often convert an HDD to GPT without losing data --in Diskpart in Admin mode simply type Convert GPT.

    As for Windows install --you don't need to set any preference for booting the windows media -if your computer is set for UEFI it will load the appropriate software --same as MBR.

    Note - if installing clean with MBR HDD make sure you don't have more than 4 HDD's online at install time and sometimes a built in SD (or Micro SDHC card) card can cause problems too so eject it before doing the install.

    You CAN have GPT HDD's on non UEFI computers --they just can't be the BOOT device !!!!.

    After install you can then re-connect HDD's and SD card again - the problem only occurs with MBR installs.

    Don't re-enable secure boot after re-installing Windows -- it will hose you up -- simply leave it off -- IMO this was a STUPID feature - possibly the idea was for Ms to actually have Windows fixed in ROM (eventually). For home computers where you might often want to boot all sorts of things it's a royal pain. It's probably OK for "Work" / locked down machines to ensure people don't boot unofficial OS'es or bootlegged software.

    Cheers

    You can Disable Secure Boot and UEFI to install from a non UEFI Windows version and device (Ie) Flash Drive.
    Or better yet, create a bootable UEFI Windows USB Flash Drive using Rufus in my signature. Leave Secure Boot and UEFI turned on UEFI Bootable USB Flash Drive - Create in Windows

    Asus motherboard with UEFI firmware.
    - Asus UEFI setups allow for both UEFI and Legacy BIOS (aka CSM) booting to be enabled.
    - You do not need to change the default UEFI firmware settings, if you install Windows 10 64-bit in UEFI mode or Legacy BIOS mode.

    Asus motherboard default UEFI firmware settings.
    - When you boot in UEFI mode, Secure Boot is automatically turned on.
    - When you boot in Legacy BIOS mode, Secure Boot is automatically turned off.

    Asus motherboard default UEFI firmware settings.
    - When you boot from the Windows 10 USB/DVD in UEFI mode (UEFI prefix in the boot menu), then Windows setup creates a GPT partitioned disk.
    - When you boot from the Windows 10 USB/DVD in Legacy BIOS mode (without UEFI prefix in the boot menu), then Windows setup creates a MBR partitioned disk.

    Asus motherboard default UEFI firmware settings (see screenshots below).

    CSM (Compatibility Support Module) > Launch CSM
    - [Auto]: The system automatically detects the bootable devices and the add-on devices.
    - [Enabled]: For better compatibility, enable the CSM to fully support the non-UEFI driver add-on devices or the Windows UEFI mode.
    - [Disabled]: Disable the CSM to fully support the Windows Security Update and Security Boot.

    Secure Boot > OS Type
    - [Windows UEFI Mode]: Execute the Microsoft Secure Boot check. Only select this option when booting on Windows UEFI mode or other Microsoft Secure Boot compliant OS.
    - [Other OS]: Get the optimized function when booting on Windows non-UEFI mode, Windows Vista/XP, or other Microsoft Secure Boot non-compliant OS.

    edit:

    If you install Windows 7 64-bit in UEFI mode, then you must select the following option.

    Secure Boot > OS Type > Other OS (default: Windows UEFI mode)

    Or you get the error message "Secure Boot Violation" after installing KB3133977 from the Windows Update, which makes the system fail to boot into the operating system.

    Hi Debgram, If you would set your Secure Boot to Disabled and the CSM to Auto, it will enable either Secure boot or MBR boot. This will be useful when you are booting from another device such as many USB drives or a DVD drives. If you would like to, you can enable secure boot and set the CSM to disabled after the install. However, if you do that you are going to have to change those options any time you need to boot into many other devices. But, for the install I would disable Secure Boot and set CSM to auto. Once you are installed in UEFI Mode, you can change them however you want them.
