I presently have a 100GB hard drive and want to upgrade to a WD 250GB hard drive.

I upgraded my BIOS to the latest A14 version.

However, the computer will not recognize the new 250GB drive. Upon boot up I recive a message that I have a "non-bootable" drive and when I look in the BIOS it tells me that there is no hard drive installed.

Do I have to use some software to "trick" the BIOS into believing that it is working with a smaller HD?
