[Luna] trying to install red hat on a used computer, and having problems

[Nathan]

 I believe when you boot it, and the very first screen comes up that lets you 
select if you want the graphical or the safe installation, you type something 
in there. Try pressing F1 or F2 and see if the screen changes. Somewhere it 
will say 'check media' or 'test media'.

OR, once you boot into the basic installer, before it tries to install 
packages it will have an option test verify the media.

Being 7.2 it may be just old enough that it does not have any of this. In 
which case you may need to run md5sum against the disc in windows and compare 
it to the md5 red hat has for 7.2. But this is beyond me. I'm not a windows 
guy.
