I'd research EasyBCD and see if that will do that.
Guys I have partitioned my single HDD and installed Windows 7 Professional on both partitions, I have installed Microsoft Office Professional 2003 on drive D:\ and Microsoft Office Professional 2007 on drive E:\. When I reboot the computer I get two boot options Windows 7 or Windows 7 is there a way of renaming these options and making it easier to select the drive with Office 2007 etc.
Watsy?.
