    there is no boot manager in BIOS


    My laptop has dual boot system- windows 10 and ubuntu. After a update in ubuntu, pc is not booting, showing an error to install an operating system. In the BIOS, I found no boot manager boot device to select.I tried startup repair from a bootable USB drive, but it can not repair.Note: It takes much longer time to access BIOS. And every step of startup repair also take too much time.My laptop is UEFI and secure boot eanabled.

    :)

    Windows stuck in automatic repair; Can't access BIOS/ boot menu

    I've changed the boot order through both BIOS and the boot manager, as my original post stated. Neither did anything, but both were functional in the past. Neither listed the windows boot manager, either. Previously, it would boot just as expected whenever
    other media was set as the first option, so I'm pretty sure there are no issues there.

    As my original post suggested, I've already tried out the steps you gave. I've gone through all the options listed in the boot menu, UEFI or not.

    My BIOS and boot menu settings were at their defaults when all of this started, so that's been tried already, if those are what you're referring to.

    there is no boot manager in BIOS

    Windows boot manager

    There could be some system conflict triggered after the said changes. To help you with your concern, we suggest that you perform a clean boot. A
    clean boot is performed to start Windows by using a minimal set of drivers and startup programs. This will help to determine what is causing the issue on the Windows boot manager. To do this, click on this
    link and scroll down to the
    How to determine what is causing the problem by performing a clean boot section then follow the steps listed..

    Note: If the installation is successful and the issue has been resolved. Please go through the section “How to reset the computer to start as usual” to reset your computer to the normal startup.

    Let us know how it goes after performing the suggested steps.
