Issue/Introduction
Symptoms:
After a successful conversion, you may experience these symptoms:
-
The resulting virtual machine fails to start the operating system
-
The resulting virtual machine fails to boot and does not issue a STOP error
-
The boot process halts at a black screen with a blinking cursor
-
You may receive these errors:
-
Windows could not start because the following file is missing or corrupt:
C:\windows\system32\hal.dll
Please re-install a copy of the above file.
-
Windows could not start because the following file is missing or corrupt
C:\windows\system32\config\system
-
Operating System not found
-
Non-system disk or disk error
-
NTLDR is missing
Press any key to restart
-
A disk read error occurred
-
The Master boot record (MBR) of this virtual machine's hard disk does not contain valid bootstrap code. It is likely that the MBR was corrupted by an incorrect guest operating system installation or some other reason. The virtual machine cannot continue and will now power off. (For advanced user: The MBR is the last disk sector accessed by the virtual machine before the error.) Please consult our Web site at http://www.vmware.com/info?id=18 for common troubleshooting help.

STOP 0x79 MISMATCHED_HAL
-
The master boot record (MBR) on this virtual machine's hard disk does not contain valid bootstrap code. MBR corruption is usually the result of a failure installing the guest operating system. The virtual machine will power off when you click OK.

Resolution
Validate that each troubleshooting step below is true for your environment. These steps provide instructions or a link to a document. These steps are ordered in the most appropriate sequence to isolate the issue and identify the proper resolution. Do not skip a step.
- Ensure that during step 3 of the conversion (View/Edit Options), you choose the appropriate disk controller for your operating system.
- If the source contained more than one hard disk, try changing the virtual hard disk order on the resulting virtual machine by removing both virtual hard disks, then adding them in the reverse order. For information on adding secondary disks, see the Virtual Machine Administration Guide .
- Rewrite the master boot record on the virtual hard disk and restore the Windows boot files using the FIXMBR and FIXBOOT commands from the Recovery Console. For more information, see Repairing boot sector problems in Windows NT-based operating systems (1006556).
- Verify that no data was corrupted during the conversion process. Corrupted data can affect the virtual machine's ability to boot successfully. For more information, see Checking for disk corruption on the destination after using vCenter Converter (1006559).
- Verify that the hardware abstraction layer (HAL) library file is correct and that it is not corrupted for the destination virtual machine type. For more information, see HAL cannot be identified upon conversion of a virtual machine using vCenter Converter and fails to boot (1038576).
