While installing a window the setup is saying cant load your HDD drivers. how to resolve this problem?

plz help me resolve this problem
tell me how can i make my HDD bootableI am trying to read what you said.

It looks like you want to install windows again on your hard drive. But for some reason you forgot how it was done before. This would be much easier if you had made a backup system.
In the case of Windows XP it MAY be necessary to install a SPECIAL driver for the SATA hard disk drive. You must have the driver all ready on a floppy disc. When the setup starts you must hit F6 and INSERT floppy disc in drive.

thanx for the reply
