It may be the data in the ISO image was downloaded rather than the disc 
itself. If you still have it around, try running:

sha1sum <filename>

and compare the output to what's quoted on


If it's different then try downloading again from a different mirror.

The packages selected for installation may not be in regions that are 
corrupted. If I recall correctly, my parents' machine (FC1 or 2?) hangs with 
a black screen for a few seconds when X is started, then continues as normal 
- nothing to do with the installation media. The machine is set up to use the 
integrated graphics facility on its Intel motherboard (can't remember model 
or chipset offhand).

In the case of a disc error I think it stops, ejects the disc for it to be 
cleaned and put back in (could be wrong about this though). Most problems 
during the RPM installation stage will display an error message and abort the 
install - the only option being click "OK" to reboot (or CTRL+ALT+F<n> to 
look at the technical blurb in the other virtual consoles).

GRUB is installed at the end of the process, so if you are doing a fresh 
install you won't be left with a bootable system. For an upgrade the existing 
GRUB will probably be intact, but the system will be in an indeterminate 
state and some or all parts may not work properly.

(You'll probably need to be root for the second of these to work.) In case the 
message doesn't actually include the word "error", try the following 

dmesg | less
less /var/log/messages

the shell after each command.
