Windows 10: I have over 15 entries in my Bios Boot option DEL key on my Asus motherboard, some are...

I dual boot my computer Windows 10 and Mint and most of the boot options don't work to access the correct operating system.I have used bcdedit, efibootmgr and cleared my Clock on my motherboard attempting to get this cleaned up but it keeps adding entries over time.Windows 10 is installed on a MBR partition Disk 0 and Mint installed on UEFI partition on a second physical drive. I suspect my BIOS issues are with this configuration.When I select the Ubuntu or P2 device when selecting a partition during BIOS boot, a dual boot window comes up but selecting Windows causes an error and selecting

how to remove fedora boot option frim uefi boot

Hello, I'm Felipe and I'm an independent Community Advisor, and I'll do my best to help you.

To completely remove the boot option for the deleted Fedora operating system, you will need to access the UEFI settings on your Asus B350 F Gaming motherboard. Here are the steps to do so:

Reboot your computer and press the key to enter the UEFI settings. The key may vary depending on your motherboard, but it is typically F2, Del, or Esc.

Once you are in the UEFI settings, navigate to the Boot menu.

Look for the boot option that corresponds to the deleted Fedora operating system.

Select that boot option and press the Delete key or the key designated for removing the boot option on your motherboard.

Save the changes and exit the UEFI settings.

After completing these steps, the boot option for the deleted Fedora operating system should be removed from your UEFI settings. If the boot option reappears after rebooting, there may be other issues with your UEFI settings or the motherboard itself, and you may need to consult the Asus support team for further assistance.

 

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.
