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