Hello, i have hp/compaq dc7800 pc and win7 ultimate 32bit. I try to go to advandced boot options (hitting f8 at startup), but i only get keyboard error. (42 301 keyboard error) In windows it works ok. I have tested this pc with 4 keyboards and results are all same. Other win7 computer boots ok to that menu with those keyboards. I have 100mb system reserved partition and c partition. Do i need some other recovery partition to get it working? Thank you.
