Startup Manager Missing Workaround:

1) Start by making use of the Windows Vista installation disc to boot the system into "System Recovery Options" and click on "Startup Repair" on it.

2) The system looks for the causes that may cause the startup failure in the set order. In the background of the system, the boot recovery checker automatically tests and analyzes Windows updates (which may also lead to boot failures if the patch installation fails), system disks, disk errors, disk metadata, target operating systems, boot logs, and other contents.

3) If the system finds the cause of the boot failure and repairs it, it will enter a dialog box indicating that it has been found and tried to fix the problem.

4) Windows Vista will not display the fault cause found by default, just click the "Finish" button to restart the computer to complete the recovery operation.
