After my windows totally crashed i thought it might be time to format my hard drive, taking it out of my computer and placing it in a friends i pulled off all the flies that i needed to keep. after putting it back into my computer i attempted to format it through the windows boot disk but i have no clue if it worked or not because when i went to install windows it said a windows directory was already present but the system said that the hard drive was completely empty (i only have the one drive). after restarting the computer it said that now my DVD drive was Master 0 and it could not dectect any hard disks. i went into BIOS and my hard disk is under Master 3 instead of 0. now when trying to install windows, windows says it cannot not detect any hard drives.
my hard disk is SATA Seagate Barracuda 160 gb
