Do you have more than one HD on that computer? As in, one has
Windows
or something else and the other has at least FEdora on it? If so, when
the installer asks you to check which HD's you want to utitilize during
install, check them all. You will have the choice afterwards on which
is to be used only for mounting/storage and which for the actual
installs.
You may be correct, but this is terribly counter-intuitive. It certainly
looks like the purpose of those check boxes is to allow the user to
specify which disks the Fedora installer may use to write the new system
it will install. Even more important, this looks like an opportunity to
tell the Fedora installer about disks it should not modify because they
contain data the user knows should be preserved.
I think the Fedora installer should be allowed to read other
(non-installation) disks and identify items it may add to the new
Fedora system's boot menu.
It seems folly to tell Fedora's installer it may use a disk I know
contains another operating system or data I wish to keep, and hope it
will all come out right... I will correctly select subsequent options
regarding type of installation, then review/modify the configuration and
make any desirable changes before installation commences and writes data
to disks I have already said can be used for the new installation.
