I am starting to work for sunlife Microsoft Office Professional 2007 Keygen tomorrow and need my laptop to run Windows 7 Starter Key for their software. Currently i have Office Professional Plus 2010 Key installed. I want to know if I can split my hard drive and when computer boots I can choose xp or Office Home And Student 2010 Keygen. 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!
