I  format my laptop work for sunlife 
 Microsoft Office 2007 Standard Key tomorrow and need my laptop to run 
 Windows 7 Serial Key for their software. Currently i have 
 Microsoft Office 2010 Professional Product Key installed. I want to know if I can split my hard drive and when computer boots I can choose xp or 
 Office 2010 Update Key. So I can use xp for work and windows 7 for home. Since i don't have the cd for 
 Windows 7 Home Basic X86 I don't want to remove it completely. Any suggestions and help would be appreciated!
