3rd Master Hard Disk Error

[CSEatOSU]

I took my windows machine, took out the hard drives, put in a new one. I had some problems installing Hardy from the CD but finally got it running last night. I did some reboots, updates, and everything was fine. Shut the computer down before bed. I woke up this morning, started up the computer, now I get this error message at startup:

3rd Master Hard Disk Error
Press F1 to Resume
I press F1 and it goes to a screen like this:

Intel UNDI, PXE-2.1 (build 082)
Copyright <stuff>

For Realtek <stuff> Gigabit Ethernet blah blah blah

CLIENT MAC ADDR <stuff>

PXE-M0F: No boot filename received

PXE-M0F: Exiting PXE ROM.
It does all that about 3 times then I get:

Reboot and select proper Boot device
or Insert Boot Media in selected Boot device ans press a key_
I NEED SOME HELP!!!

Thanks.

I figured out how to enter BIOS during setup. I pressed 'Delete' to get in there during setup. I went to check the boot sequence and it goes:

1st: Floppy Drive
2nd: CD/DVD Plextor
3rd: Hard Drive
Boot From Other Device: [No]
