  • BIOS Disk Boot Option settings don't hold (GA-Z97X-UD5H-BK)

    Weird problem: Frequently get boot errors on way to Win 8.1, and when go into BIOS, find that boot option #1 setting for Samsung 850 EVO Pro SSD system drive has switched to something else (Samsung is in SATA3 Port 0). Usually takes a couple of boot option resets to get it to hold and the computer to boot normally into Windows. Doesn't happen every time, but often. F7 BIOS (UEFI). Mobo is revision 1.1. CPU is not overclocked.

    Background: Switched from GA-Z68X-UD3H board to the Z97X-UD5H-BK in early May and soon after that switched system drives from a 128gb Plextor SSD to a 256gb Samsung 850 EVO Pro (the latter was cloned, then did an in-place repair install, which now looks was unnecessary). Soon after, I started having frequent boot errors that shouldn't have been occurring, with one or more of the following: disk read error, Boot\BCD error, Windows boot stalling, MBR Error 1 suggesting to boot from a floppy drive (don't have one), blank screen. After those, usually one to three reboots led/leads to a successful start up. At some point, I decided to check the BIOS settings and discovered two things:

    - Boot #1 option has changed from the Samsung SSD, typically to either the Plextor DVD drive, or by dropping the HDD/DVD drives from the list and showing only Samsung, Canon and disabled.

    - After resetting the boot options, it takes at least another reset/save to get them to hold, tho saved each time. After the first reset, BIOS boot options typically only show Samsung/Canon/disabled as boot options, as just mentioned. It takes another reset for all the drives to show in the lists (all drives are listed under Peripherals > SATA configuration, no matter what). The reboot in between is typically the one that shows a blank screen.

    I got a support ticket with Gigabyte and they suggested disconnecting all the USB connections except the mouse as the starting point for a test. But it made no difference. In fact, it took four boot option resets to get to Windows. That's when I figured it worth posting here.

    Any ideas? Thanks,

    Have you tried the latest beta bios?
    Z97XUD5HBK.8a

    Make sure that your drive is first in your drive priority options.
    Then it should show first in your boot priority option.
    Install the latest RST driver (in top of the default win 8.1 one)
    Oh and make sure you have the latest SSD firmware installed (with Samsung Magician)
    Your OS Win 8.1 is installed in Legacy mode (mbr), not UEFI mode (disk would be partitionned GPT) so be sure to:
    - enable CSM support
    - disable secure boot
    - disable fast boot

    Will check other possible solution if that doesn't work.
    regards

      Thanks for the reply. It appears that in the process of switching SSDs, I lost UEFI along the way.

      Here's what I've done:
      - flashed 8a bios
      - boot order has been correct, except when something has thrown it off
      - installed latest RST driver and then reminded myself why RST is disabled in bios: computer won't start with it enabled (others have found that too)
      - Samsung firmware is current; update of latest Magician pending
      - What are CSM support and secure boot? Why not fast boot?

      What I've done so far has had zero effect. Btw, after reattaching the SATA cable I had about 20 good boots with maybe one "no disk found" among them. Then this afternoon (Wed), when the computer seemed to be having some slowness, I rebooted and the whole thing started again. My hunch is that this is going to take a reinstall of Windows to find out if it's the Win 8.1 cloning, the Samsung SSD or something about the BIOS.

        I wrote:
        "Install the latest RST driver" NOT enable RST in the BIOS
        RST drivers package contain AHCI, RAID and software.
        You are probably in AHCI mode (at least you should be) thus the AHCI driver install itself

        Your Win 8.1 is install in Legacy mode (since you clone it from a system that do not support UEFI) so:
        - Run msinfo32.exe and on the Right pane check "BIOS mode". It will most likely show: Legacy (not UEFI)
        - you need to enable "Compatibility Support Module" (CSM)
        - disable fast boot since it is a UEFI option
        - disable secure boot since it is a UEFI option

        If you do a fresh install a Win 8.1 do it in UEFI mode IF your graphic card support UEFI booting and only IF (Please post your specs next time)
        Assuming it is the case:
        - disable CSM support
        Follow this guide carefully including removing partition before installing:
        UEFI (Unified Extensible Firmware Interface) - Install Windows 8 with

        Good luck and come back if no resolution on SSD boot order, or anytime

          Re: BIOS Disk Boot Option settings don't hold (GA-Z97X-UD5H-BK)

          Just to be sure,
          Each time you plug or unplug some hardware or you flash the BIOS, ALWAYS
          - Clear your CMOS (reset bios)
          - "Load optimized settings" in the bios then SAVE, reboot and enter BIOS settings again and finalize your settings, SAVE and Reboot.

          Then you're good to go.
          Hope it helps

            Re: BIOS Disk Boot Option settings don't hold (GA-Z97X-UD5H-BK)

            Thanks. There's a Windows 8 features setting in BIOS that I had set to "other OS" for a good reason that I can't recall now. When set to Win 8, CSM then shows ("always"). Secure boot seems disabled by default because I'm not using a password (?). Fast/Ultra Fast boot do work with my setup. Except for the cable connection and monitor (DVI) and LPS to a USB card, all of the external hardware is USB based, which shouldn't require resetting the BIOS.

            All of these changes have had no effect on the problem.

              Hi,

              See above comments in red.

              Again, you are trying to use Windows 8.1 UEFI features in BIOS with a Windows 8.1 operating system which was NOT installed in UEFI mode. That create conflicts. When you set your OS option in BIOS to "Win 8" Your BIOS is searching for a UEFI boot device (with EFI boot loader) and since your SSD (OS) is NOT setup in UEFI it will skip it and probably end up with the DVD ROM as your first boot option (since DVD Rom is the way from which someone will install widows 8.1 in UEFI).

              So make up your mind if you want to do a fresh install of Win 8.1 in UEFI mode or if you're keeping your current config.

              Note: Your graphic card Sapphire HD7750 do not support UEFI booting but you can still install Win 8.1 in UEFI boot mode (read the above guide about installing Win 8.1 in UEFI, and enable CSM support putting it at "always"). I would advise you do a CLEAN with DISKPART to reinitialize the SSD (which is initialized now in MBR but need to be initialize in GPT like all your disk in win 8.1 UEFI mode). That will erase all your data on your system disk. You can always convert a MBR non system SSD (or HDD) to GPT in disk management section of Win 8.1. That being said, in your case, even if your Win 8.1 OS is installed in UEFI mode you will not be able to use some UEFI features like secure boot and ultra fast boot because you will not boot in full UEFI mode (CSM support disabled) because you graphic card do not have a GOP and will boot using an option ROM (opROM) instead of full efi gop driver.

              If you want to keep your current config:
              Read your manual from around page 53

              - Reset CMOS, Reboot
              - Go back in BIOS and load optimized default settings
              - Set "OS option" to "Other OS"
              - Set "boot mode selection" at "UEFI and Legacy"
              - Set "Storage boot option control" at "Legacy only"
              - Save, reboot, shut down, remove power cord, put back power cord, reboot
              - Go back in your BIOS and finalize settings for your SSD first boot, save, reboot.
              - Install latest chipset driver (important)
              - Install latest RST driver
              - Install USB driver if Win 8.1 didn't (especially USB 3.0)
              - Install graphic drivers
              - Install other drivers

              DO not play with UEFI settings features in your BIOS. That is for a Win 8 (or 7 under condition or 8.1 or 10) installed in UEFI mode (which is NOT your case)

              That should do it.
              If not, go back to Gigabyte support and open a ticket or contact them.
              Hope it helps

                I'm getting ready to leave for the weekend and will look again next week. I do think there's a disconnect here, but want to go through the steps - virtually all of which I've done already! - to see one way or the other when I have time.

                I've had a ticket open with Gigabyte on this for several weeks, but they couldn't figure it out. Which is why in the midst of it I posted here.

                    Re: BIOS Disk Boot Option settings don't hold (GA-Z97X-UD5H-BK)

                    I completed the list through "Go back into your BIOS..." and the rest had already been done (all but one done before this thread started, as were almost all of the settings). No effect - boot problem still there.

                    I suspect the problem lies with the three month old Samsung drive or with the Windows boot file being corrupted or not recognized for some reason much of the time. I can literally run 25 starts that fail, and then leave the computer off for awhile and it starts up on first or second try. A strange thing is when I run "bootrec /rebuildbcd" (from Windows install media), it usually recognizes one Windows installation and gives me the option to "Add installation to boot list? Yes/No/All." When I answer Yes, the response is "the element can't be found" or something to that effect. Not sure what to make of it, except either the SSD is bad or the cloning of the old SSD wasn't successful. Thanks,

                      I completed the list through "Go back into your BIOS..." and the rest had already been done (all but one done before this thread started, as were almost all of the settings). No effect - boot problem still there.

                      I suspect the problem lies with the three month old Samsung drive or with the Windows boot file being corrupted or not recognized for some reason much of the time. I can literally run 25 starts that fail, and then leave the computer off for awhile and it starts up on first or second try. A strange thing is when I run "bootrec /rebuildbcd" (from Windows install media), it usually recognizes one Windows installation and gives me the option to "Add installation to boot list? Yes/No/All." When I answer Yes, the response is "the element can't be found" or something to that effect. Not sure what to make of it, except either the SSD is bad or the cloning of the old SSD wasn't successful. Thanks,
                      You are mixing up different things. You are wasting your efforts repairing the BCD Store without repairing the MBR, the boot loader and/or partitions structure (see: diskpart) among other things to do prior to repair the bcd store for that matter.
                      There is good guides on the net to do that. Your googlefu skills you have to practice if you absolutely want to clone your drive that was installed in Legacy (MBR) mode.

                      I suggest you find a UEFI GOP vBIOS for your graphic HD7750 card and re-install Win 8.1 in UEFI mode. That way you will be able to play with your favorite features (it seems) like ultra-fastboot and secure boot.

                        Running "bootrec /rebuildbcd" is part of the MBR repair! Have also run diskpart a couple of times and it likewise failed at some point. For cloning, I use Todo Backup. As far as I can find, one person developed a UEFI/GOP bios patch for the Sapphire 7750, but that is for the low profile version. Not sure yet if it would work with the Ultimate. Sapphire Radeon HD7750 - Low Profile Edition UEFI/GOP VBIOS

                        One thing catches my attention about the failed starts is that it's much more likely to occur, or occur continuously rather than just once, is on restarts or while the computer/Samsung SSD is still warm, than first thing in the morning or after sitting awhile.

                          See above
                          Fix also the Win file system (sfc /scannow)

                          That being said:
                          Samsung support/toubleshooting page indicates some solutions for your problem including setting your SSD as "Dynamic Disk" in Windows "Disk management"

                          It seems to be that your Samsung 850 pro might have a firmware problem and it seems to be quite common. Contact Samsung support or browse internet. There are solutions posted here and there on the net.

                          Regarding your HD7750, there is some ways to do a GOP hybrid vBIOS. I did it with my HD 6850. I went the manual way and with "HD7xxx Series UEFI Patch Tool BETA" with same result.

                            Teddybehr, Thanks for your post!! I've just put a question up on the Anandtech Samsung 850 beware of the firmware thread, and done the same on overclock.net "Do you want UEFI Gop on your 7950/7970? I can add it to your bios!!" thread. If it is a Samsung firmware issue, that would take pressure off having to do a clean install real soon.
