Hi , bit more info: on first attempt Windows loaded and installed ok. Had a problem with Graphics card so powered off and reconnected the pcie cables. Then tried to start again , turned on , black screen came up ans said insert cd into disc drive and press enter it then starts to install it says "we couldn't find any drives , to get a storage driver click " load driver". Don't have a cd for the hard drive .
Tried switching cables /ports etc but no joy.
Went into bios and no drives are showing.. but windows installed somewhere on the first attempt????
Thanks for your help
