after you boot into the windows installation disk from bios, there will be a screen that tells you to "press any key" to install windows. Due to resolution problems, you may not see that, and after few seconfs it will go back to bios if no key is pressed. Try booting from the dvd again but this time as soon as you do, keep pressing space key on your keyboard
Also, have you tried changing the hard drive configuration from AHCI to IDE (if it's not already) ? I know someone outside of this forum that couldn't install windows without using "IDE" mode.
force bios option rom is just a thingy for the raid reporting.
basically it checks for raid connected to it and if it finds nothing it would just do nothing. but if you force bios on it, it would say something like "no drive installed"
Okay, so i tried with my brothers windows 8 (which i cannot use, because he will be using it) and it works fine, so i guess in must be my copy of windows 7...
Its not the copy of windows 7, its the bios settings, turn off UEFI, or in boot options select the drive with windows 7 on it without the UEFI infront of it.
