|There is two different things here that need to be clarified...|
1) you enter the BIOS (set-up) by pressing a specific key when the computer first starts. This is usually the F1. F2, Del or some other specific key.
a)While in the BIOS does the harddrive show up?
b)Do you have the correct setting for the drive to boot...ie...SATA, RAID, IEDE, ??
2) If the Bios shows the harddrive (#1 above)
then the harddrive is not being seen because you have either failed to install the SATA drivers through the F6 method or they were installed improperly or the BIOS setting (#1b) is not set right.
This was the original installed harddrive you are trying to reformat/reinstall the OS to? Or is this a new Harddrive being installed????
If it is a new drive then it must be set-up properly to be seen...The new drive should have come with a installation utillity disc from the manufacturer, or information on how to obtain the disc by going to the manufacturer's website and downloading it and making the boot disc to prep the new drive and make it ready for installing the operating system. This may also cause the harddrive to not be seen from the BIOS or from installation of the OS.
