Is it possible to burn the live iso of tails on a partition of main drive and boot into it from the grub , i already tried using dd but it always ended up corrupted and unmountable i tried to boot the partition from the grub command line but it cant even read the partition. Is it even possible?
You need to add --removable flag into your grub to show removable devices.
