Hello:
Just a couple of suggestions. Dunno if they will help or not, but perhaps worth giving it a whirl
Check that your BIOS is using setup defaults or optimized defaults etc. Then, if you can disable items in your BIOS that you are not going to use, such as serial port etc.
If that does not help then you could try starting the installer with linux vesa
and see if that gets you anywhere?
