Please do not clutter the issue with BIOS "stuff".
I am looking for old fashioned flow chart describing Linux ( Ubuntu) UEFI booting process.
I can RTFM for grub, UEFI - however I just do not understand how the entire process works,
I can start with
1. Install Linux using ISO
2. Select GPT partition format
3. Let installer build EFI (boot) partititon etc.
4. After install - on power -up - setup UEFI
5. Then setup "grub/grub2 "
6. After initial setup - what files are actually used during NEXT boot process?
/default/grub ?? grub.cfg ??
