I am starting to work for sunlife Office 2007 Pro Plus Activation Key tomorrow and need my laptop to run Windows 7 Home Basic X64 for their software. Currently i have Office Professional Plus 2010 X64 installed. I want to know if I can split my hard drive and when computer boots I can choose xp or Office Pro 2010 32 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 I don't want to remove it completely. Any suggestions and help would be appreciated!
