Created Linux instalation flashdrive on my notebook like thousand times before. Simple dd if=img of=/dev/sdb . Tried installing system from it but somehow doesn't work. And the it hit me. I have both magmetic drive and SSD in my laptop! So insted of flashdrive, I have bootable beging of my SSD where my encrypted lvm used to be :-( Luckilly I lost just EFI, boot, swap, rootfs, few git repositories and ccache.
