    Pre Boot Menu - Just Curious


    Just trying to see if there is any rhyme or reason to what I'm seeing. The attached image is not what my pre boot menu actually looks like. That's because at that point in the boot process its impossible to take a screen grab, so I found this image on line.

    In mine, the top left just says "Windows 10" with a count down timer. Below that is "Macrium Reflect", and below that is "Windows 10 Safe Mode" and in the top right there's "Windows 10 Safe Mode with Networking."

    The "Macrium Reflect" was put there by that same program.The "Safe Mode" and "Safe Mode w/Networking" was put there using the Tutorial available here. But the actual menu items are not really my question. My question is this. Sometimes I'll hit the power button on my Dell laptop and that pre boot menu is as bright as a light bulb. Other times its really dim and they only way it gets bright is if I move the mouse (but then the 10 second timer for the Windows 10 selection goes away).

    I'm sure there are many, many other things for me to worry about, but like the thread title says, I'm just curious as to what determines the brightness of that opening screen.

  2. No startup boot menu

    Hello Kimoefat,

    Thank you for posting your concern in Microsoft Community and welcome to the Windows 10 Family.

    As an initial recommendation, I would suggest you to access the System configuration utility and check if the Operating System installation path for Ubuntu exists. To do so, follow the below steps.

    • Type msconfig in the search bar and select System Configuration from the search results.
    • Select the boot tab in the System configuration console to check if the installation path for Ubuntu exists.
    If it exists, next logical step is to check if the boot menu time out has been set to 0, which results in Boot menu not showing up.

    The boot menu time-out determines how long the boot menu is displayed before the default boot entry is loaded. It is calibrated in seconds. To change the boot menu time-out, use the Bootcfg
    /timeout switch. Valid values are from 0 through 999. You cannot use Bootcfg to set an indefinite time-out.

    You can run the following Run command line to set the boot menu time-out accordingly. To do so, follow the below steps.


    • Press Windows key + X, select
      Command prompt (Admin) to bring up elevated Command prompt

    • Type in the following command: bootcfg /timeout 10

      timeout 10
      will set the time frame to 10 seconds
    However, if the Boot path for Ubuntu does not exist in the boot menu of System Configuration utility, I would suggest you to check if the Ubuntu is overridden by the Windows installation or if the Ubuntu installation files are corrupted.

    Hope the above information is helpful. If you need further information, feel free to write to us and we would be happy to help you.

    Thank You.
     
  3. Pre-loaded games won't uninstall

    I'm not really into some of the games that were pre-loaded into my PC but when I try to bring up the games from the Start menu and click on 'uninstall' it takes me to the control panel, and I don't see the games listed there for me to uninstall. Suggestions, please? Thanks! ~P
