Fail to install Windows7

No, nothing connected.

Yup, same problem on that, a blank black screen and a underscore symbol on top left of my screen.

I try it before, the problem still there, the problem it can read my boot option, it just can't start read my windows7 installation dvd files and install. I using my original Windows7 disk and i try using for other non-apple product, it all work fine. I try reinstall OS X with online too, make it clean and try install Windows, but it just can't.

I try it once before, i download Windows7 X64 from official site and use PowerISO Burned with slowest rate, the result were same too. I wonder is that are my touchpad malfunction that make my keyboard failure so it make the Windows7 installation fail to load the files? My internal keyboard still can use when i press Alt key to choose boot option, but when i load my Mac OS my keyboard can even press a button only left me a led light. I didn't plug any usb when i start the installation, because the Alt key still function at boot option page.

Ok, i will try this way, i will reply again once the result completed.

Hey LonerT, i already tried the way that you give me, now i get the result were same, Boot Camp Assistant done after restart and boot into my DVD-drive, the thing go same as i said, a black screen and a underscore symbol on left top and it just keep blinking. It just dun load the Windows 7 installation file and continue the installation process.

Yes, it just show a DVD-Disk icon name with 'Windows', but once i select it, it just give me a black screen with a blinking cursor. It just won't start load the windows files ans start install.
