Where (which files) did you make changes to your own OS name?

if i remember well, grub.cfg

If you change grub.cfg, loopback.cfg, isolinux.cfg or txt.cfg, these will affect what you see in the **grub** menu in various situations.

However, if you want to change the entry you see in you **System BIOS** (when you press F12 or Del or other key during boot up), that is something different... and I'm not sure that is possible.

You can check out efibootmgr which will allow you to see and remove existing entries (from an installed system)...

    $ sudo apt install efibootmgr

    $ sudo modprobe efivars

    $ sudo efibootmgr -v

I suspect the name "ubuntu" is hard-coded / compiled into one of the binary files (may be in the `shim` package ???)

Can you help with this problem?
