Your comments, Stanron, are appreciated, but I went ahead prior to reading your post. Installed dual boot set up sucessfully, without loss. However, this is not my main computer, so any disaster will be a minor one.

The learning curve begins/continues....

So far, so good. Managed to get Audacity happenning, along with various audio/visual applications, plus basic internet and word processing.

Still lacking Tag&Rename type software. Any suggestions?
