You certainly have more knowledge than I do and I sure appreciate you 
being here and helping us out, but I don't see where it is confusing. I 
always have more space on my disks than I need. Setting up another 
partition allows me to do a fresh install. Then I can remain productive 
on my old system while I get the new setup just like I want it with no 
pressure to rush. I don't anymore but I used to have a MySQL database on 
my local machine that I used everyday. The first time I moved it to the 
new OS it took a while to figure it out this way I had minimal down time 
with it.

Yes I could have just upgraded. I have done that in the past but it 
seems like just when I needed to get something done I would have a glich 
of some kind and I would have to scramble to get it fixed.

i was getting concerned about getting this problem fixed. I read as much 
as I could find about it and sown loaded and installed it. took a deep 
breath and hit the fix button. Turns out it worked and I can now boot to 
all 3 OS's.

Thanks again for your help.
