windows format

i started 1st reinstall with create parciption (didnt notice it lael) , harddrive went from 250gb to 131gb

2nd one, fucked with bios, -> master/id/bus was 0 etc. still at 131gb

3rd one , found my hdd from bios, was under secondary hdd, tried to change it into 1st ,no success.

so i have tried 3 reinstalls on my machine, cant get missing 120gb nowhere

did def settings on whole bios, still missing 120gb,WHATS WRONG??????!
