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