post and tell me what your board is.
does windows say it cant find your drive then?,is your bios seeing the drive?
it may need the driver for your sata controller when you try and install windows,which you have to press f6 when windows installer first runs.the driver will need to be on a floppy disc.if you post what board you have we may be able to help you find the driver.have you still got the original mboard cd? you can sometimes get the driver from that disc(using another machine).
fill in your sys spec in user cp or post your specs please.
EDIT-thx,look at your hard drive,has it got a little thin probs red cable,or a flat or thick round one?
