I have opened up my PC after an year or so.I tried to install windows XP on it but when the setup was aborted in between.Again when I restarted it, then setup says no hard disk found on your computer. I thought it will be a better idea to format it once.I connected my harddisk to my friends PC and made it as sec slave. I checked in the BIOS setup that my hard disk was properly detected(along with primary hard disk of my friend). But when I exit the BIOS it says Sec Slave HDD error.If I continue by pressing F1, it boots normally from the primary hard disk and does not show any drives of my hard disk. Please suggest me what to do.
