Theres a very easy way to add RE options in the boot menu.
1) One needs 1 file- winre.wim. Winre can be made in WAIK or simply extracted from the install dvd. Its inside install.wim (DVD\Sources\install.wim), so just mount install.wim with imagex and copy off the winre.wim file (about 150 mb size).
2) Create a folder on any drive say D:\Sources and paste winre.wim above into it.
4) In Easybcd, add a new boot menu entry of the WINPE type, name it something appropriate and point it to D:\Sources\winre.wim. Save settings.
5) Done. Now when you reboot, there'll be an option called <whatever name you gave>, selecting it will take you to the system recovery options.
If you dont use easybcd, then you'll need to copy off Boot.sdi as well from the install dvd and paste it into C:\boot, then configure bcdedit manually.
