Unable to start the Virtual Machine "Ntldr file is missing"

  • Parallels Desktop 9 for Mac Standard Edition


I cannot start the Virtual Machine: "Ntldr file is missing".


"Ntldr" is a system file of Windows OS. The most common reason for this error is when your virtual machine is trying to boot from a non-bootable source. In other words if the partition boot sector has become corrupt or isn't properly configured, you may receive the "NTLDR is Missing" error.

The corruption of boot sector can be caused by the hard reboot of your Mac while the virtual machine has been started.


Please perform the following:
