The system is not detecting a new drive. Go to a CMOS setting called Drive Configuration, Hard Disk Settings, or even Devices And I/O Ports. It lets you configure the hard drives, CD-ROM drives, and diskette drives. PCs made in the past few years come with an automatic-detection program that enters configuration data into CMOS. If your system is older than that, or if you installed a drive your system is not detecting, enter the drive information manually to prompt your system to detect it. You do this in CMOS, where your drive information is located. This area is often called Drive Configuration, Hard Disk Settings, or something along those lines. There will be an option where you can choose between manual detection and automatic detection. Other than that, I would suggest replacing the CMOS battery. I doubt it is a bad BIOS or incorrect bios flash becasue you woud only get a Check Sum Error at post.
