How do I modify the boot menu for Windows 7?

Solution 1:

EasyBCD provides an "easier" way to manage the windows boot loader.

I don't think it provides that much extra functionality beyond bcdedit, but if you'd rather not play with the command line it's a second option.

Solution 2:

In Windows Vista and later, you should use the bcdedit.exe command line tool to edit the boot menu configuration instead of editing the boot config file by hand. The exact commands will vary depending on exactly what you need to do, but there is extensive documentation from Microsoft as well as a helpful tutorial on a Windows 7 Forum.
