How to create a bootable pendrive from ISO image
To install a fresh version of the Debian I need to prepare a bootable USB stick.
First make sure I am writing on the right device. Yes, it is a very old 2GB USB stick.
fdisk -l | grep sdc Disco /dev/sdc: 1,9 GiB, 2017984000 bytes, 3941375 setores /dev/sdc1 * 0 774143 774144 378M 0 Vazia /dev/sdc2 4060 9243 5184 2,5M ef EFI (FAT-12/16/32)
Then transfer the ISO image bit by bit to the USB stick:
dd \ bs=4M \ if=debian-live-11.5.0-amd64-standard.iso \ of=/dev/sdc \ status=progress \ oflag=sync
