Extended Hard disk not recognised

[netsense]

Hi
I have a Windows 7x64 Pro VM on Linux Mint 17.2 x64. I need to expand the hard disk from 35GB to 50GB to allow an upgrade to Windows 10, so I ran

Code: Select all

VBoxManage modifyhd /home/edwin/VirtualBox\ VMs/Win7AccountsVM/Win7AccountsVM.vdi VMs/Win7AccountsVM --resize 50000

I got the expected 10% ... 100% response line, and in the VM settings the disk now shows up as 48.83 GB - close enough. However, when I boot into Windows > Control Panel > Administrative Tools > Storage, I don't see any unallocated disk space to extend the volume into. I rebooted into a GPartEd live CD, and the result is the same.

Can someone explain what is happening, and how to resolve it?
