The boot sector is corrupted, which can also cause the system to not boot properly, and also need to enter the Recovery Console in Windows 2000/XP, with fixmbr (repair master boot record) or fixboot (repair boot sector) commands.
In Windows Vista, in the same way that the system automatically detects startup failures, Windows Vista will be able to easily find the crux of the problem and automatically use the BCDMD command to fix it.
If there is no system startup failure, just want to test the "IQ" of Windows Vista, then Windows Vista will politely and firmly indicate that startup repair does not detect the problem.
From the performance of the startup recovery feature, Windows Vista is undoubtedly reassuring. It is commendable that the system does not require us to have the ability to start fault scheduling, but to give all the work to Windows Vista itself, which is to be affirmed.
