  1. Can't find Operating System


    I am running Windows 10 and Ubuntu 18 on separate partitions. When I start the laptop I get a screen saying 'Cannot find operating system' with a button to shutdown. When I restart holding f12 to choose a boot disk I kit enter for the internal hard disk. This will load grub where I can choose Windows or Ubuntu. I can now boot into either one normally. Why can it not find the operating system on the initial boot?
    Thank you

    :)
