I have a GW M series with Win 7 Ultimate Laptop
It will not see the cd/dvd rom at all. Not even in bios.
I have changed out the dvd rom without benifit.
I have not tried to boot to external dvd rom to re-install system and it
desnt seem to see the external dvd, USB, at all anyway.
Not sure what is going on at this point. Any suggestions appreciated.
