I didnt understand the last part, " then i restarted all is fine working" - do you mean after that your HD was detected and everything is working fine?

If not, then check your BIOS settings, in the Bootup devices section make sure HD is selected as first - save , reboot and see if it works.

You can later make your CDROM/DVD drive as 1st and HD as 2nd. In one of the systems i have worked with, having DVD as 1st resulted in the HD not booting up unless i place any sort of CD (non-bootable) into the DVD drive. Could not fine the problem so just placed HD as 1st bootup device.

ino bios is set to boot from hd but as i told u suddenly on switching on computer it says boot device not detected i mean hard disc so i reconnect sata cable after taking it out from sata port on motherboard then it works fine
