BCDEdit Command-Line Options
Boot Configuration Data (BCD) files provide a store that is used to describe boot applications and boot application settings. The objects and elements in the store effectively replace Boot.ini.
BCDEdit is a command-line tool for managing BCD stores. It can be used for a variety of purposes, including creating new stores, modifying existing stores, adding boot menu options, and so on. BCDEdit serves essentially the same purpose as Bootcfg.exe on earlier versions of Windows, but with two major improvements:
- BCDEdit exposes a wider range of boot options than Bootcfg.exe.
- BCDEdit has improved scripting support.
However I am lazy and when I can use a graphical tool I will do that all the time.

iReboot a simple yet effective reboot helper tool. This app sits in your taskbar at startup (only taking up 400KB of memory!) and lets you choose which operating system you want to reboot into. Instead of pressing restart, waiting for Windows to shut down, waiting for your BIOS to post, then selecting the operating system you want to boot into (within the bootloader time-limit!); you just select that entry and you done !
