    Bug report: DE3815TYKHE: 0054: Linux UEFI boot fails with 2 USB flash drives inserted, boot=ok with only 1 USB flash drive

    ProBackup.nl

      Environment:

      - DE3815TYKHE, 8GB RAM

      - BIOS version 0054

      - no SATA drive attached

      - only USB Flash drives attached

      - only UEFI boot enabled (not legacy boot)

      - OS Selection: Linux

      - Fast boot: disabled

      - Boot USB devices first: enabled

      - Boot Network devices last: enabled

      - Unlimited boot to network attempts: disabled

      - Bios setup auto entry: disabled

      - Boot devices: USB enabled, all others: disabled

      - Secure boot: disabled

       

      Boot order:

      1. UEFI : USB : Linux Boot Manager : PART 0 : OS Bootloader

      2. UEFI : USB : SanDisk Cruzer Force 1.27 : PSTY 0 : OS Bootloader

       

      USB media:

      1. Samsung MUF-32BB (bootable)

      2. Sandisk SDCZ71-016G-B35 (Cruzer Force 16GB)

       

      When Samsung (#1) is inserted in front USB slot, the DE3815TYKHE computers boots the Arch Linux system on it via \efi\boot\bootx64.efi.

       

      When Samsung (#1) is inserted in front USB slot and the Sandisk is in a back slot, the DE3815TYKHE computer boots into:

      1. EFI default loader menu, ...10 seconds countdown

      2. Reboot Into Firmware Interface, ...10 seconds countdown

      3. Intel Visual BIOS

       

      Regression:

      - it doesn’t matter whether the Sandisk is plugged in the upper or lower back side USB slot

      - it doesn’t matter whether in which slot the drives or plugged, even when Sandisk is in front slot and Samsung is in back slot, the system will not boot the Linux system, but Visual Bios instead.

       

      Workaround:

      1. unplug Sandisk USB flash drive (not desired)

      2. press F10 boot menu, and select “UEFI : USB : Linux Boot Manager : PART 0 : OS Bootloader”
