Hey, all ... thanks so much for your help (daughter just had my 5th grandchild and have been away for a bit, so sorry for my slow response) ... Couple of things ... my OS drive has data on it, so can't reformat it in order to set it up so it can be seen on both my mac os and my pc os. I 'can' run a Ubuntu live CD to read the drive and then move the data to my pc ... great idea and that's what I will try first ... now ... different question ... does it ever make any sense to try and set up my pc as a dual boot ... mac os and pc os. I can use boot camp on my pc to run windows on it ... is there anything that lets me do the same on my pc?
