Existe nova versão (1.3). Essa versão resolve problema com a inicialização de algumas máquinas. Apenas repita todo o processo com o novo disk2vhd.
This update to Disk2vhd makes more Windows XP and Windows Server 2003 VHDs bootable by updating their MBR and boot sectors to be compatible with Hyper-V and Virtual PC and by installing the Intelide driver if it it’s not already installed. It also optimizes image creation by not copying paging and hibernation files.
