laptop cannot see sata hard drive

i recently deleted a partion to get rid of vista since doing so my laptop no longer sees the hard drive as primary master it see the cd drive as primary master instead, i have used all sorts of tools to reformat the hard drive it is set as primary drive and is set active but it still says no hard drive connectedwhen trying to reinstall windows. when looking at devices in bios it sees hard drive, can anyone tell me how to get bios to read hard drive as master thanks in advance for any help
