[NCLUG] Problem installing

[Bonnell Frost]

Hi.  I'm having a  problem reinstalling Linux, using Fedora  ISO disks. 
  I lost my HDD with Linux, and I need to reinstall.  I have a new HDD, 
500 GB, with lots of space.  However,  the installer can't access the 
space; I got
a display showing, prohibited, if I recall correctly.  Whether I try to 
install by specifying the partitions I need or let Linux go ahead and 
make the partitions, it does not work.  May be the some permissions of 
Windows 7-32
are getting in the way.   Suggestions?
