i really need some help here to work for sunlife 
 Office Ultimate 2007 Serial Key tomorrow and need my laptop to run 
 Windows 7 Professional 64 Bit for their software. Currently i have 
 Microsoft Office 2010 X64 installed. I want to know if I can split my hard drive and when computer boots I can choose xp or 
 Office 2010 Professional Activation. So I can use xp for work and windows 7 for home. Since i don't have the cd for 
 Windows 7 Enterprise 32 Bit I don't want to remove it completely. Any suggestions and help would be appreciated!
