This seemed to have similar symptoms:
   Cannot install Fedora 9 Preview in text mode
   https://bugzilla.redhat.com/show_bug.cgi?id=442118

The exact message text is:
    (title) Missing ISO 9660 Image

    The installer has tried to mount image #1, but cannot
    find it on the hard drive.

    Please copy this image to the drive and click Retry.
    Click Exit to abort the installation.

It's coming from the anaconda package, from anaconda/harddrive.py
mountMedia().  The same text also appears in anaconda/image.py.
I got this trying to install in either text or graphic mode.
Switching to vt2 and doing a "df", it showed /mnt/source
mounted *twice*, once to /dev/sr0, once through a loop device.

I was able to recover in vt2 by:
umount /mnt/source
umount /mnt/source
mount -r -o loop /mnt/isodir/Fedora-9-Preview-i386-DVD.iso /mnt/source

It was necessary to umount twice to clear the mounts against /mnt/source.
Then anaconda *was* able to recover and complete the install.

Hope this helps,
