Windows Vista bootloader can only be modified using bcdedit.exe or for short, BCD (Boot Configuration Data) along with commands and parameters. Microsoft made this changes to allow more possibilities of configuration and to be prepared for future technologies.

This is challenging for average users that just want to add an entry for another operative system or to choose which of them to boot first.

EasyBCD is a great application that lets you manage the bootloader entries with easy to understand options. It has entries for Windows XP or earlier versions, Mac OS X and Linux.

It has a backup feature in case you want to restore the default values. Also, it can look for errors and enable debug mode, a feature that lets you see what is actually happening at boot time.

If you have more than one operative system (this is known as Dual-boot or Multi-boot), or want to install another one along with your current installation of Vista, EasyBCD can help you add or manage this entries with ease.

Here is a FAQ from Microsoft about BCD.
