Replying to my own post. Do I need to change partitions "a:" (currently part of volume tmp) and "d:" (currently part of volume root) Also with this configuration do I need to shrink the size of any of my partitions. (I am unclear as to if I have 8k at the beginning of the drive) I can delete my current d: partition and make it smaller if that is needed. I just don't grok this yet :-( thanks again for any help.
