I think this may have something to do with your monitor or choice of data cable. My computer is hooked up to a TV via HDMI cable, and it does exactly the same thing yours is now doing. Everything works fine, but nothing appears on screen until the login screen. However, when I connected my backup 19" LCD, it started to display pre-OS images and text on that, then switched the primary display over to the TV once the OS had been loaded. Try a different monitor or video cable, if you have any available.


Now that I think about it, it may be that the BIOS either doesn't recognize some displays, or doesn't recognize HDMI as a valid video output, whereas the OS does.

Do you use an external monitor? The boot up sequence will ALWAYS go to the original default monitor instead of the external (mine does this as well on my other laptop and I can see the boot sequence on my original screen but my external is blank until the login screen).

I doubt its the VGA/DVI cable, since its fine on Windows GUI.

Its more likely a possible corrupt bootfile.

Something turned off GUI boot which isn't a bad thing (it shaves some seconds off your boot time) though it doesn't help much if something goes wrong with your boot sequence. All your F8 safe mode options will still work fine though.

Here's how to force restore the boot sequence (WARNING: commands must be type exactly! Mistyping this will most likely break your system!)
1. Open Command Promt as an administrator (Run as Admin)
2. Type: bcdboot %WinDir% /l en-US

Restart computer to confirm if it did fix or not.
