I am trying to install Linux Mint 13 on my VirtualBox. I created a new VB hard drive with a dynamically allocated size of 8GB (I have tried with fixed size as well). I have tried installing Linux Mint 13 64-bit and 32-bit and every time during install, it sees the hard drive size as 8.6GB (bigger than I made the drive to be) and if I proceed, after install it only sees the drive size as 4.5GB and of course fills up very quickly.
I am on a Windows 7 64-bit host OS with 8GB of memory (4GB which I have been allocating to the guest). I didn't have any issues with install. Everything goes smoothly until the drive size is shown in my guest.
What am I doing wrong? Should I try an earlier version (I have already downloaded both architectures of 13)?
