I asked this question the other day, but apparently not precise enough. I do NOT want to "convert" my Boot Camp installation to a virtual one. I want to know if ONE installation in Boot Camp can be CONTINUED to be used by booting via Boot Camp, while also when I am using OS X, log into it virtually? So, I do not want to convert it over and lose the capability to log in via boot camp. A couple of days per month I need to primarily use Windows for a client. Those days I want to login to Boot Camp and use Windows. On the other days, I want to be able to use Windows via virtual access. As I may need to randomly access a Windows program but will use OS X Leopard the vast majority of work days. Can I do this? Or, do I need two separate Windows installations, one in boot camp partition and one in virtual partition? Also, same thing for Office Pro 2007 in Windows??? Reinstall for both partitions required? Allowed? Possible? Do I need separate Windows keys and licenses? Thanks for all assistance. I am trying to ensure best of both worlds here. As I am fortunate enough to use Leopard 28 days of the month and need Windows only a couple of days. But, would like flexibility to use Windows either via Boot Camp or via Virtual installation from Leopard. Happy Holidays.
