    Cant boot windows 10!

    Hi guys,
    I am having Asus q502la laptop I wanted to install windows10 in it but it didnt boot any DVD or USB so i changed it from uefi to legacy boot mode by disabling secure boot and fast boot and by enabling csm mode !!
    And then it booted my DVD and I installed win10 successfully ...
    But now its taking about 20 minutes to boot win10 but once you are inside the windows it works so fast and fine !!
    At first it used to boot windows in only twelve seconds but now its taking so much time !!!
    I thought you might be cuz of I disabled uefi mode so I just enabled uefi mode and disabled legacy mode but now it is not booting windows in uefi mode!!
    Please help
    Asus laptop convertible q502la
    1tb sad
    8gb ram
    4gb graphics card
    i5 processors @2.2 and 2.8 GHz
    American megatrends bios version 209

    Hi Aryan. Welcome to the TenForums @Aryan Sagar

    First I would go online and use the Microsoft Media Creation tool and create a bootable USB key. Just use the tool and an 8GB USB key.

    I assume this is a clean install and there is no personal data in the line of fire, correct. You must remove personal data to prevent undesirable accidental results. Disconnect drives that will not receive the OS.

    I would put it back in UEFI boot mode and disable CSM. Leave secure and fast boot off. Boot from UEFI USB option, please confirm you see it in boot options.

    Boot and on first screen Shift + F10 to get to command prompt. Then....

    List disk
    select disk 0 (ensure zero is where you want to install your OS.)
    Convert gpt (required for UEFI)

    Proceed with installation.
