First, my apologies for duplicating any previously submitted questions regarding Ubuntu and Windows related "stuff".
I just don't have the time nor the patience to browse all that is posted and then not be able to find what I am really looking for. I would like to totally move to Ubuntu and dump Windows. However, v11.04 may not work for me so will most likely have to use the v10.x. It's my understanding that "Unity" on v11.04 is not as compatible with older drivers, hardware, and such; the compatibility list(s) is not all that extensive. Of all the stuff I have on Windows XP/SP3 Home there are only a few applications I would like to run on Ubuntu. So my first question is ... can I run a Windows application on Ubuntu without having Windows installed? My next question is ... if I need to have Windows installed, how do I install and run Ubuntu on a separate internal hard drive? I don't mind partitioning but the problem with this is if the hard drive fails everything fails!
I am willing to relearn a new OS. The only real concern is learning the "command line" STUFF for manual work. It's so confusing to me. But again, I am willing to go for it.
Anyway, thanks for listening. Looking forward to the responses.
