Installer pre-GUI phase erratic

[Leon Stringer]

Hi,

I'm finding the pre-GUI phase of the F10B installer (on DVD) erratic.

(I'm talking about the phase after the boot menu and before the Anaconda 
GUI loads).

Sometimes it says "Local media detected" (or similar) and loads the GUI.

Sometimes it prompts be (in text mode) for my language, my keyboard and 
location of the install files and loads the GUI.

Sometimes it says "No install media found" (or similar) and I have to 
restart.

Is this a known problem?

Thanks,

Leon...
