I do have [debian] listed twice.

How do I remove the duplicate, or the second [debian] option from BIOS?

Thank you

BIOS Boot Option

Wiping out the MMC drive did resolve the issue.

I attempted to utilize Windows DISKPART cmd and CMD to delete the extra ‘debian’, or any other ‘debian’ boot options:

How to delete duplicate bootloader from dual-boot setup?

In summa, attempt such steps within Windows CMD that is executed as “Run as Administrator”

diskpart

DISKPART>list disk
....
DISKPART>sel disk 0
DISKPART>list vol
....
DISKPART>sel vol 3
DISKPART>assign letter=G:

After this, I had to close the CMD window and reopen (or just exit from DISKPART)

> cd /d g:
>dir /B

If you find efi folder then change directory to:

>cd /d efi

If needed, delete the directory:

>rmdir /S ubuntu

This is a rough outline of what is required to delete an extra boot option via Windows OS terminal.
