    UEFI boot entry in BIOS


    Dell Inspiron 15 3515 Windows 10.In my Inspiron I have two internal SSDs, one came as standard and is 125 GB and I added my own 500 GB SSD. I cloned the smaller SSD to the larger one and by using BCDBOOT was able to chose which to boot from at startup. Both boot up just fine. However, I want to permanently use the larger SSD but in my BIOS there is a reference to the smaller one 125GB in the UEFI section, see below - How can I change the UEFI entry to be my larger 500GB drive?

    :)

  2. UEFI remove unwanted boot entries from BIOS solved easily

    OK, FINALLY I figured it out. It would appear as though the last few people who used UEFI Shells died years ago, and I'm the only one left. But in case there exists a person who owns a Dell XPS 17 L702x system, here's how you delete boot entries from the BIOS.

    Step 1. Download the Phoenix Technologies UEFI Shell: Dropbox - UefiShellX64.efi - Simplify your life

    Step 2. Format a USB flash drive in FAT32, and create a folder named "EFI", and inside that, create another folder named "boot".

    Step 3. Copy and paste the UEFI Shell utility into the boot folder, and rename the file "bootx64". The full path should look like this: EFI\boot\bootx64.efi

    Step 4. Reboot your computer, and rapidly tap the "F12" key on your keyboard until you get to the Boot Menu. Scroll down to "Setup" and hit Enter.

    Step 5. Now that you're in the BIOS, use the arrow keys on your keyboard to scroll to the Advanced tab. From there, scroll down to Boot Configuration. In Boot Configuration, set UEFI Boot to "Enabled" and Legacy Boot to "Disabled". Hit the Escape key to go back and then go to the Exit tab. Select the option to "Exit SAVING Changes", and go back to rapidly hitting that F12 key on your keyboard.

    Step 6. Once at the Boot Menu, select your USB Mass Storage Device, and you'll boot into the UEFI Utility.

    Step 7. From there, type: bcfg boot dump -b

    This will display a list of boot entries. Take careful note of the "Option" numbers, and make note of the one that you want to delete. In my case, it was Option 05 with a description of "RAID Array". DO NOT CONFUSE OPTION NUMBERS WITH THE BOOT HEX NUMBERS!!! For example, Option 05 had a hex number of "Boot000A". Others will have such numbers as "Boot0005". That is NOT the number you want. You want the option number. It's a two character number after the word "Option". Hit the "Enter" key until the list has fully displayed.

    Step 8. Once you know the Option number of which boot entry you want to delete, simply type this command:

    bcfg boot rm XX (where XX is the Option number of the entry you want to delete).

    For example, in my case, my RAID entry was Option 05. Therefore, my command looked like this:

    bcfg boot rm 05

    Step 9. Hold the power button to turn off your computer (I don't think there's a "shutdown" command for UEFI Shells).

    Step 10. Turn your computer back on, and go back to rapidly tapping that F12 key while doing it. Once at the Boot Menu, go back into Setup. Once in the BIOS, go back to the Advanced Tab, scroll down to Boot Configuration, Set UEFI Boot to "Disabled" and Legacy Boot to "Enabled". Don't forget to exit saving changes.

    And that should do the trick. Hopefully I helped at least one person with this post.

    Hi there

    @dictum
    @logictonic1

    Another way
    Boot up any UEFI Live Linux distro and then ensure you have efibootmgr installed on it. (Or those that have dual boot with Linux -- boot into that - also ensure efibootmgr is installed).

    now run the efibootmgr command and you'll see a list of boot entries for example in my case :

    delete the HEX number(s) of the boot entries you want to delete

    Job done --even easier !!!!!

    Cheers

    Believe it or not, you should be able to use my method posted above, except you may have different steps when it comes to your BIOS. However, the steps regarding the EFI shell should be the same. EFI shells are something you boot into pre-operating system, so they're universal. Three notes I want to mention:

    #1. "Backspace" in that EFI shell doesn't work as expected, so if you make a typo, you're just going to have to hit Enter and re-type the command.

    #2. I found out there is a reboot command in EFI Shell (Step 9.). It's Ctrl+Alt+Delete. You can do that instead of hard powering off the system.

    #3. If the EFI Shell freezes on you (it froze on me once), just hard power off your system, and reboot back into your USB drive with the shell on it.

    But otherwise, my instructions should work with your (or any) system.
