If you're running build 5253 or later, the Boot.ini isn't used, but instead replaced by BCDEdit.exe. It's run from the command line, and replaces the Bootcfg tool that's used in XP... and I believe you need elevated priveleges in order to run it (Start | All Programs | Accessories | Right click Command Prompt and select Run Elevated). Open the command prompt , and type bcdedit /? for a list of available switches you can use with the tool. I don't think you need to specify a switch with the bcdedit command in order to display the entries that appear in the boot menu... you may need to though in order to edit it, in addition possibly adding an identifier after the switch.
