Hi David. Yes, I made the labels for the partitions during the original installation:
/dev/sda1 = / (primary partition) /dev/sda2 = (extended partition) /dev/sda5 = swap (logical partition) /dev/sda6 = /home (logical partition) So /dev/sda2 has no label, as it is just an extended partition, which "holds" logical partitions: /dev/sda5 /dev/sda6
