As always, make sure you have a backup of your data.
Since we're going to modify the partition table there's a chance it could be corrupted or lost.

Run 'sudo fdisk /dev/sda'.

Use 'p' to list the partitions.

Make note of the start cylinder of /dev/sda1.

Use 'd' to delete the /dev/sda1 partition.
