After resizing VHD file with

VBoxManage modifyhd "c:\VMs\WinXP.vhd" --resize 50000

and successful operation I cannot boot from this VHD:

FATAL: No bootable medium found! System halted.

Previous size was 29.9 GB. Host is Win7, guest on this VHD is WinXP.

When I run VirtualBox VM with linux live and GParted the VHD, it shows 50GB of unallocated space. On the other side, when I run linux live on Virtual PC and GParted VHD, it shows 7.9GB of unallocated space.

I have tried recovery by Gparted, no partitions found. I have tried recovery console from WinXP installation (fixmbr...) nothing changes.

I have also tried everything from Cannot boot after vhd hard drive is resized in VirtualBox

I have a backup of VHD, but it's few months old, and I'd hate to do everything again (it was my DEV station).

What should I do?

I'm experiencing this as well. I have not been able to locate a solution to this as of this post. Keep an eye on forums.virtualbox.org/viewtopic.php?f=6&t=59561. –  user306040 Mar 8 '14 at 5:58
