    UEFI: Windows Boot Manager


    Hello guys first-timer here. I was wondering if I messed up something in my computer. Sorry for a bit lengthy post.

    What happened was, a few days ago I changed my power supply into a new one and decided to clean case along the way. I had disconnected everything and reconnected once I'm done with my cleaning. I booted it up and was surprised that after the motherboard manufacturer icon, I was greeted with a blinking underscore in a black screen. Seeing this I went and checked my BIOS setting and saw that the boot priority is 1. HDD 2. CD Drive and at the end of the list is UEFI: Windows Boot Manager. I tried it again and it still went to the blinking icon screen.

    I then changed it to the UEFI: Windows Boot Manager and it went to the usual windows 10 icon screen but now it takes me around 2-4 minutes to reach the login screen. To be honest it's a minor inconvenience on my part waiting 2-5 minutes until the login screen but I was wondering what might have caused it.

    Here's my system specs if it helps:

    CPU: Intel i7 2600
    Mobo: MSI h61m e23
    PSU: Corsair CX650m
    Ram: GSkill 8gb
    GPU: Asus GTX 1070
    Storage: Western Digital Caviar Blue 500gb
    OS: Windows 10 Pro Version 1903

    Thank you for the kind assistance.

    You might have accidentally changed a few other settings in the Bios. Boot back into Setup (Bios) and Set the Bios to Default, or Optimized Default. Before Saving and Exiting, check the Boot Order after setting to Default, and make sure UEFI: Windows Boot Manager is first boot.
    If you are able to view the order of the Windows Boot Manager, make sure your HDD/SSD is first boot device in the Windows Boot Manager, Save and Exit.
