    Looks fine to me, although I'm not a BIOS expert! Enter bios.... wait a few seconds ... exit bios without saving. Does boot fine?

    On most Acer systems, you can use the F12 key on boot to select the drive or network from which loading the operating system. In case the F12 option does not work, you may need to enable this function.

    2.Press the right arrow key to select Main.
    3.Use the arrow keys to navigate to F12 Boot Menu, and press ENTER.

    Samsung UEFI/BIOS firmware has bug, If the Acer way does not work, try DISABLING UEFI & ENABLING Legacy BIOS in CSM.

    Some OEM manufacturers are locking end-users out of the options in uEFI/BIOS firmware on consumer PC’s, on business PC’s there not.

    Windows Hardware Certification Requirements for Client and Server Systems


    Microsoft said:
    Mandatory. On non-ARM systems, the platform MUST implement the ability for a physically present user to select between two Secure Boot modes in firmware setup: "Custom" and "Standard". Custom Mode allows for more flexibility as specified in the following:

    It shall be possible for a physically present user to use the Custom Mode firmware setup option to modify the contents of the Secure Boot signature databases and the PK. This may be implemented by simply providing the option to clear all Secure Boot databases (PK, KEK, db, dbx), which puts the system into setup mode.

    If the user ends up deleting the PK then, upon exiting the Custom Mode firmware setup, the system is operating in Setup Mode with SecureBoot turned off.

    The firmware setup shall indicate if Secure Boot is turned on, and if it is operated in Standard or Custom Mode. The firmware setup must provide an option to return from Custom to Standard Mode which restores the factory defaults. On an ARM system, it is forbidden to enable Custom Mode. Only Standard Mode may be enabled.
