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