No videso Output after installation

Hey,

i downloaded the iso of the current 2.7 release, prepared a usb stick and installed my pc (optiplex 75 with core2duo cpu and nvidia geforce 9300 GE)

the debian installer worked fine and i had a working video output. When i try to boot the system i loose the video output while booting the operating system.

Also the recovery mode fails. Are there no nvidia drivers included? Can i force a minimal mode with a failsafe graphics driver to get cli?

best regards,
Kai

If this is a Optiplex 755, I would try removing the video card and using the on board video
