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