Hello.
 Updated BIOS to newest and boot mode is grayed out(UEFI), before with older BIOS version this option was active but only variant was UEFI. I can change secure boot enabled/disabled. Is there any way to enable legacy mode?
 Other strange thing is i cant boot from USB flash drive.

    Why do you want to change to MBR/Legacy mode? Best format is UEFI which is the default for this laptop. Anyway, see this extensive guide “How to switch UEFI BIOS to Legacy BIOS on a PC” and see your laptops bios "Boot" mode settings and descriptions below and change settings accordingly

    Boot Mode - Select the boot mode. Select “UEFI” (default) or “Legacy”. When the boot mode is changed, changes will only take effect after a reboot. If the user insist to change the mode, the boot priority order will become gray out unless the user switches the boot mode back to the original boot mode settings.

    Secure Boot - Enables or disables secure boot check. Default is “Enabled”.

    Boot Priority Order - Displays bootable devices based on the Boot Mode selection

    NOTE:

    • Wired connection will display Network Boot-IPV4 and Network Boot-IPV6 as two separate network boot devices.

    • After Windows 10 OS is installed, a Windows Boot Manager will be generated and displayed on top of the boot device priority.

    • Non-physical boot devices can be deleted in the Boot Priority Order List, this includes A trusted boot entry and Windows Boot Manager.
