    windows boot manager


    I wanted to dual boot my windows 10 home desktop and install windows 7 on it. I made a new partition with no problem and followed instructions from u tube on how to install windows 7 from a cd. I went into BIOS, put boot from a cd on top, and restarted computer. Put in my windows 7 cd, typed in cd key when asked and let it run. It installed on the first step, and shut down before starting to copying windows files, when it restarted, I got a boot managers window that said a hardware/software change might have a file that is signed incorrectly or damaged. Another paragraph said to insert windows cd and click on repair computer, I don't have a cd for windows 10, my laptop and desktop are both running windows 10 and are about 2 years old, I don't beleive a cd was included with either one. At the bottom of Boot managers screen was File:\$windows~\windows\sys32\win/dad.efi. Status OXC0000428, and digitial signature could not be verified. How can I get rid of the boot managers window, and why didn't windows 7 install. My Windows 7 CD is from my old laptop and about 13 years old or so I think. I have wiped my old laptop clean several times and reinstalled windows 7 with no problem. Any help would be appreciated.

    :)

    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.

    Or at the very least, make sure that your hard drive boot order is correct, because it will take the first writable drive in the boot list to determine where to put the boot loader. As Jester suggested, pop the Windows install disk in, make sure your boot order is correct (or unplug the drive,) and run repair. It's really that simple.
