Is my PC using UEFI ? (Refind)

[pawRoot]

Hi

I have installed Debian in EFI mode and then installed Refind on top of it, but now
i'm not sure if i am booting through EFI or not, because when i press F11 after starting computer
there is no "EFI" next to Refind bootloader.

Code: Select all

lsblk

├─sdb2   8:18   0 220.5G  0 part /
└─sdb3   8:19   0  11.9G  0 part [SWAP]

Code: Select all
