[Trisquel-users] Installing Trisquel on PC with Gigabyte UEFI dualbios

[andere]

I cannot for the life of me get a live cd of any distro to run on this pc. I  
can get the live cd to be read, and I can see the splash screens, but when I  
choose to "try without installing" or "install" options, I get a black screen  
with a white, flashing dash and it just hangs indefinitely.

What on earth is gigabyte uefi dualbios and why can't I get any live cds to  
run?
