    More interesting is how to shrink it of course.

    Both increasing and decreasing disk size are covered in the VirtualBox documentation though thankfully.

    Hi there

    probably an EASIER way is to use your standard backup software like macrium reflect.

    There are 4 alternatives here - works for VMware VM's too.

    1) increase partition size (on same virtual HDD)
    2) decrease partition size (on same virtual disk)
    3) increase total Virtual HDD size
    4) decrease total Virtual HDD size

    For all 4 options backup your VM first with say a program like macrium reflect to external media (USB HDD or whatever).

    for options 1, 2 download something like GPARTED / Partition manager -- you need the ISO. Set your VM to boot from the ISO and simply alter partition size (just like a REAL OS). You strictly speaking don't need to backup the VM first - but better safe than sorry --especially if you use the VM a lot.

    For options 3 and 4 -- delete the VM's from disk -- create a new one specifying the HDD size you want and choose Manually install OS -- don't use any automatic GUEST creation wizards. Now set the VM to boot from an ISO of your backup / restore program --Macrium reflect is usually a good one.

    Restore the OS -- you can attach the USB external drive where the backup is stored.

    Job done and you have a decent backup too.
