I have a cubieboard (similar to Raspberry Pi). I wanted to clone the 2GB micro sd card to a 8Gb card.
umount (all partitions on sd) dd if=/dev/sdb of=/root/image.img change sd card dd if=/root/image.img of=/dev/sdb
then in gparted I resized the data partition.
But the system did not boot. I have no log files nor monitor output.
Question: Are the dd commands correct? is it /dev/sdb and not /dev/sdb1? This would be the one partition only.
