Warning: Linux utilities tend to be simple but very powerful i.e. typing incorrect commands (especially the directions of < and > below) can result in your source drive being wiped out – suggest to back up important files before proceeding. Proceed with instructions below at your own risk.

1) Install pv;

sudo apt-get install pv

2) Determine source/destination drives/disks;

sudo parted

Enter print all in the parted command line then look for /dev/sda, /dev/sdb etc. and associated partition descriptions to determine source/destination drives/disks.

3) Start the actual cloning/imaging (assumes /dev/sda is source and /dev/sdc is destination);

sudo su
pv < /dev/sda > /dev/sdc

4) Install new drive then use linux gparted utility to extend partition sizes.

Above was tested using an Ubuntu 14.04 LiveUSB with an internal source drive containing a Windows 10 and an Ubuntu 14.04 partition. Windows did report a strange error during initial boot after new drive was installed but sorted itself after restarting. No issues found booting into the Ubuntu partition.
