See if you have two cables connected to that drive. One is the power, and it will have usually have just four wires, One red, one yellow, and two black. The other cable is for your data, and it will generally be a many-wire flat cable, which might be about 1.5" wide with up to 40 wires (if it is an IDE cable) or it could be about a half inch wide with about 7 wires in it (if it is a SATA cable).

Also make sure that the other ends of those cables are also connected to something. The power cable may be daisy chained from, or to, another drive device, but it doesn't have to be, since it may come directly from the power supply. If it does connect to another device that helps in figuring out if power is actually on that cable. As for the data cable it should be connected right to the motherboard (rare exceptions where be plugged into an interface card, but most likely you don't have that).

Other than making sure that the cables are correctly inserted, you shouldn't have too much of an issue. You can interrupt the bootup process to get into the BIOS. To get to the BIOS depends upon your computer's manufacturer. I think your Dell will probably as simple as pressing the "DEL" key soon after power on (check with your Dell documentation). In the BIOS you can immediately tell if the hard drive can be read, by looking for the drive info on one of the pages of the BIOS.
