Resize a Hard Disk for a Virtual Machine

Our Virtual Machines are provisioned using Vagrant from a Linux base box to run using VirutalBox. If the Hard Disk space runs out and you cannot remove files to free-up space, you can resize the Hard Disk using some VirtualBox and Linux commands.

Some assumptions

The following steps assume you've got a set-up like mine, where:

How to Bootcamp / Dual Boot Windows 10 on a mid-2011 iMac using USB

How to Install / Bootcamp Windows 10 on a mid-2011 iMac using USB

Apple has released support for bootcamping Windows 10, but only on 2012 Macs and later. Despite not being supported. it is possible to install Windows 10 on earlier iMacs and it seems to run quite well.

IMPORTANT: Unplug all external and physical hard drives (where possible) that you won't be installing to to avoid accidentally erasing them. Also make note of which drives and partitions remain (e.g. System and Storage hard drives), and be super careful to not erase the wrong one.

RECOVERY: If you nuke your machine, restore your time machine backup. Instructions here.
