Sounds like the configuration I've got now. My hard drive crashed - I was running Windows XP. When I got my notebook back, I did the dual boot thing and mostly use Ubuntu and occasionally boot into Windows XP for a few specific things. I'll have to try Virtual Box to see if I can boot if I can boot into XP even less.
I’m still new to the Virtual Box situation. My main thing in XP is Quicken. While I’ve gotten Quicken installed in Ubuntu using Crossover, it’s very limited and I gave up using it. I still go to windows for that.
Once concern I have with Virtual Box is resources. I have 1.25 Gb RAM. Just how much will be taken by Virtual Box, and the affect it has on resources remains to be seen. I can upgrade to 2Gb, and may do so. But that will come when I find the time to fool with it further. Right now, well....
