I am trying to follow this guide here : How do I remove Windows from the UEFI boot menu after custom installing Ubuntu?
The thing is when i run "sudo ls /boot/efi/EFI" i only get [ BOOT ubuntu ] but no windows so i assume afterwards when running upgrade-grab that it's on another folder and it reinstates it . "Found Windows Boot Manager on /dev/sda3@/efi/Microsoft/Boot/bootmgfw.efi"
I also saw this guide : Remove Windows entry in GRUB menu But the issue in this is that the lenovo logo boots twice if that makes any sense. Once is the normal boot lenovo and then the lenovo ubuntu logo.
So what do i need to do to completely remove windows bootloader. And when i power on my matchine it boots on ubuntu without the grub screen (to choose Ubuntu) and without seeing the lenovo logo twice .
P.s this is Ubuntu 20.0.4 and on the installation i picked to delete everything on all drives and just install Ubuntu.
