What if the boot sector of the system partition is broken

The boot sector is corrupted and the system will not boot properly. On Windows 2000/XP, you also need to enter the Recovery Console, using the fixmbr (fix master boot record) or fixboot (fix boot sector) commands.
And under Windows Vista, the same method is used to let the system automatically detect startup failures, and Windows Vista can live up to expectations, and it is easy to 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 Windows Vista's "intelligence", then Windows Vista will politely and firmly say that the startup fix can't 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 judge faults, but to give all the work to Windows Vista to do it, which should be affirmed.
