UEFI vs Grub - which one am i Using?

[yaminb]

Background:
I was planning to get an SSD to speed up booting and saw various way of copy the files and adding grub to the drive...
For example: https://www.pcsuggest.com/hdd-to-ssd-cloning-linux/ This then let me into whether I need to do anything special for UEFI and then I wondered what do I even have.

Question:
Anyways, in the interest of one question per thread, I got myself confused on whether I have grub or UEFI. I'm probably missing something in my understanding here.
It looks to me like I have UEFI enabled.

/sys/firmware/efi$ ls
config_table  fw_platform_size  runtime      systab
efivars       fw_vendor         runtime-map  vars

/sys/firmware/efi$ sudo efibootmgr 
BootCurrent: 0003
Timeout: 5 seconds
BootOrder: 0003,0000,0001,0002
Boot0000* Windows Boot Manager
Boot0001* Hard Drive 
Boot0002* CD/DVD Drive 
Boot0003* ubuntu

Yet, when I boot my Ubuntu, it definitely goes to a grub menu and I can see the relevant entries in:
/boot/grub/grub.cfg


I'm thinking the way I have this setup is UEFI is enabled and letting me boot to my drive of choice. If I choose Ubuntu, then grub takes over and I can choose the boot again?

Thanks,

You'll be using Grub either way.

The distinction is between UEFI/GPT or BIOS/MBR.

The simplest way is that the background of the Grub menu is purple if you're using BIOS and black if you're using UEFI.

By the time you see the grub menu, UEFI has already done its job. It is not UEFI vs. grub UEFI hands off to a bootloader/manager, which might be grub or windows or whatever.

yaminb; Hello -

What shows from terminal command:

[ -d /sys/firmware/efi ] && echo "Installed in EFI mode" || echo "Installed in Legacy mode"

/sys knows everything

UEFI then GRUB, not the other way around.
