    USB Flash Drive UEFI problem


    Hello Tenforums.com

    No matter what I do, my Lenovo Flex 2-14 doesn't seem to recognise my USB as an UEFI Windows bootable flash device, despite following this guide https://www.tenforums.com/tutorials/2...dows-10-a.html (Option 2), step by step.

    I am using a Verbatim 16GB USD v3.0 with Windows 10.10586 x64 on it, and I tried from all three USB-slots on the laptop.


    BIOS configuration is as following:

    Configuration:
    Wireless LAN: Enabled
    SATA Controller working mode: AHCI
    Hotkey Switch: Hotkey Mode
    Power Beep: Disabled
    AMD Virtual Technology: Enabled
    BIOS Bach Flash: Disabled

    Security:
    Adiminstrator password: Cleared
    User Passord: Cleared
    HDD Password: Cleared
    Secure Boot: Disabled

    Boot:
    Boot Mode: UEFI
    USV Boot: Enabled
    PXE Boot to LAN: Enabled
    Boot Priority Order: 1. USB HDD (..) 2. USB FDD (..) 3. ATA HDD: WDC WD200LPCX (..)

    Exit:
    OS Optimized Defaults: [Win 8 64bit]


    The Boot Menu offers these options:

    1. USB HDD: Verbatim STORE N GO
    2. ATA HDD: WDC DW500LPCX
    3. PCI LAN: EFI Network (IPv4)
    4. Windows Boot Manager
    5. PCI LAN: EFI Network (IPv6)


    My pre-installed Windows 8.1 crashed and is not accessible in any way. I spent days now trying all kind of options back and forth, but I believe the above setup should be the right one.

    Shouldn't option 1 of Boot Menu appear as something like "1. UEFI HDD: Verbatim STORE N GO"?

    Anyone got an idea what is the problem here?

    Hi, Panasonic. First thought is - can you confirm you selected FAT32 for the USB format in Rufus?

    Hi Word Man,

    Yes I can confirm I selected FAT32.

    This is what Rufus looked like prior to pressing 'Start':

    Judging from this info:
    Installing linux via usb with uefi on lenovo flex ... - Lenovo Community

    It looks like the Flex will only boot a flash drive in legacy mode.

    Thanks for bringing to my attention that thread over at Lenovo forum. It might seem to be some issues regarding Lenovo Flex and UEFI. I will have a deeper look within a few days and post here how the situation developes.

    My wife's Acer never lists the thumb drive with the UEFI connotation, but does install in UEFI mode. I use diskpart, option 2 here, http://www.eightforums.com/tutorials...e-windows.html Done that way I can install in UEFI or legacy with that same thumb drive. I have 2 laptops with UEFI and 2 desktop PC's that are legacy BIOS.

    Could you please elaborate how you came to the conclusion that your hardware caused this malfunction?
    And please, what hardware and in which sense? A hint to your solution would be great

    My current setup is exactly the same and I cannot get Win8 nor Win10 to boot from a USB stick. I Used two sticks, but both fail to boot these. Out of curiosity I tried a stick with Win7 on it and it (kind of) worked. It boots to the installation screen, but then failes due to lacking driver support from Win7 (an error message appears) .
