    how to remove gigabyte UEFI dualboot menu at start up

    Hello guys , I'm new here

    I have a problem with my bios or computer , I recently deleted everything and reinstalled windows 8.1 because I had a problem which is I get a black screen for 10-15 sec before the login screen show up ,I looked for solation everywhere ,made sfc /scan ,nothing really helped ,and now after I reinstalled the windows but with UEFI settings , get 5-8 sec black screen ,that was the first issue .

    The second issue there is a UEFI menu now showing up every time I start the PC Called gigabyte dual boot ,asking me to pick someone to boot from ,and the only thing works is windows boot manager ,I don't know how to remove this menu

    my PC is new and fast :
    8 GB ram
    sapphire R9 280 with UEFI button
    gigabyte GA-H97-D3H motherboard
    intel i5 4690
    Strix gaming keyboard
    WD HHD 500 GB
    PSU 700W

    Bios settings
    Windows 8 features > windows 8
    CSM support > always
    Boot mode selection UEFI only

    (when I pick uefi only the windows boot manager only shows ,but if choose uefi and legacy another option showing ,and I guess its my HHD but if I select it the windows fail to start)

    LAN PXE boot option rom > disabled
    Storage boot option control > UEFI only
    Other PCI device Rom priority > UEFI oprom
    Network stack > Disabled
    Secure boot > enable > standard

    Initial display output > PCIe 1 Slot
    XHCI Mode > smart auto
    Integrated SATA controller > enabled
    SATA Mode Selection > AHCI

    Should I disabled intel onboard graphics from the bios settings since im using a graphics card ?
    I have a problem with the Dxgkrnl.sys even after the fresh windows install and I don't know how to fix it as showing "did not load" but it load the first time as you can see in the log file.

    Please help ,I got fed up with this issues ,even my cheaper laptop boots up faster than my new PC , I don't know if its a problem from the GC or the motherboard ,but both are new and my PSU gives enough power 700 W

    Also just to add ,before i used to have screen flashing going black then comes back normal ,just for 1 sec ,also when the screen goes to sleep ,some times i could not turn on the screen when i click the mouse or keyboard ,and have to restart ,and i was getting blue screen of death from time to time , i suspect the graphics card hence its new and expensive.

Is there a way to massively remove all pinned apps in Win 8 Start Menu
Hi guys. I've recently needed to disable Windows 8 Start Menu due to the reason for laziness and that I wouldn't go unpinning each program one by one, after I installed the Office suite and K-Lite Codec Pack, the start menu was flooded by all the programs! Any ideas? Thanks
