This issue occurs when converting a physical machine that uses Boot Configuration Data or BCD ( Example Windows Vista, 7, Windows Server 2008, or 2008 R2 or any Windows OS). In this case, the physical machine may have some type of system, hidden, or recovery partition that results in inaccurate BCD configuration data after the conversion and causes the virtual machine reconfiguration process to fail. BCD issues can be addressed by rebuilding automatically using the bootrec command or by editing the BCD stores using the bcdedit command.
Note: If, after running the preceding bcdedit commands, the virtual machine boots and then fails with a blue screen, perform these steps to resolve the issue:
For more information, see Virtual machine fails to boot with a blue diagnostic screen stating: 7B Stop Code after using VMware Converter (2002106).
If bcdedit is not working then, navigate to advanced options and select the automatic repair address the problem.

Starting with VMware vCenter Converter Standalone 5.1, for systems running Windows Servers prior to Windows Server 2008, VSS can take snapshots of FAT/FAT32 volumes, if present, only if the source machine has at least one NTFS volume. For all Windows Server 2008 and later, this process is not supported and the FAT/FAT32 partition must be deselected.
For more information, see the Known Issue section in the VMware Converter 5.1 Release Notes.
