Specs: Windows XP
Installed new Seagate Barracuda 80G IDE drive as a master. Original HDD was a SATA and removed by the previous owner. BIOS does not recognize the new drive nor the original installed CD-ROM. Windows XP CD starts to load but stops when it detects no HDD.

Standard stuff -

ATX power supplies are always powering ATX mboards in some places even when the computer is not running, as long as the PS is connected to the mboard, the PS is switched on if it has a switch, and the PS is receiving live AC.
Unplug the case or otherwise switch off the AC power to the case whenever you do anything inside the computer case where you're changing connections or removing or installing components, including when you plug in and unplug drives.
E.g. you can fry the PS even just by plugging in or unplugging a drive if you didn't do that.

Make sure you remembered to plug the power connector into the IDE 80gb drive.

Make sure your IDE data cable is not damaged.

It is common to un-intentionally damage IDE data cables, especially while removing them - the 80 wire ones are more likely to be damaged. What usually happens is the cable is ripped at either edge and the wires there are either damaged or severed, often right at a connector or under it's cable clamp there, where it's hard to see - if a wire is severed but it's ends are touching, the connection is intermittant, rather than being reliable.
Another common thing is for the data cable to be separated from the connector contacts a bit after you have removed a cable - there should be no gap between the data cable and the connector - if there is press the cable against the connector to eliminate the gap.
80 wire data cables are also easily damaged at either edge if the cable is sharply creased at a fold in the cable.

Try another data cable if in doubt.

If you still have a SATA hard or optical drive connected:

Check your SATA data cables. The connector on each end should "latch" into the socket on the drive and on the mboard, or on the drive controller card - it should not move when you merely brush your hand against it near the socket - if it does, mere vibration can cause a poor connection of it - use another SATA data cable that does "latch", or tape the connector in place.
(There is a slight projection or bump on one side of the outside of the connector that "latches" it into the socket - it's easily broken off or damaged)

The same thing applies for the SATA power connection.

Go into the mboard's bios Setup and make sure all drive connections are set to Auto detect drives by the method Auto or LBA .

Read the label on the drive to make sure you have the jumper in the right place, if it even needs a jumper for what you're setting it to - that varies - or look that up for the specific model if it's already installed in a bay. Sometimes the info on the label is upside down with respect to the back of the drive where the jumpers are - if it shows where the power connector is in relation to the jumpers, go by that.

If the drive is on the same cable as another IDE drive, either one must be set to master (M or MA) , the other slave (S or SL) , or both must be set to cable select (C or CS) .

If both drives on the same data cable are set to master or slave, neither drive on the same data cable is detected by the bios.

Don't mix CS and master/slave settings for two drives on the same data cable - some combos work - SOME DO NOT, and in that case sometimes neither drive on the same data cable is detected by the bios..

Your 80gb drive must be connected to an 80 wire IDE data cable for it to be able to achieve is full burst data transfer speed - UDMA /ATA 100 or 133; UDMA mode 5 or 6 in XP .
The same applies to DVD combo burner drives (that can read and burn both CDs and DVDs) if the drive is capable of burning DVD-R or DVD+R disks at 16X or faster - they run at up to UDMA/ATA 66; UDMA mode 4 in XP.
80 wire data cables usually have two or three colors of connectors.
The correct end connector of an 80 wire data cable must be connected to the mboard - usually it's blue, but in any case it's the one farther from the middle connector on a 3 connector 80 wire data cable.

You may need to set the boot order settings in the mboard's bios Setup to boot from the 80gb drive. If there is more than one hard drive connected, if more than one hard drive is NOT listed in the boot order settings, there is a list in the bios Setup, often near the boot order settings - set the drive you want to boot from as the first drive in the list.

When you boot from the XP CD it doesn't "care" which drive is first in the boot order - Setup will still complete successfully.
If the boot order is wrong, it's only after Setup has run that the computer won't boot from the hard drive you installed Windows on.

Sometimes it's possible to plug in a data cable connector backwards, if the connector s have no pin holes blocked and have no rectangular external projection on one side of it (e.g. some UDMA / ATA 66 80 wire data cables; many 40 wire data cables).
The stripe on one side of the data cable must be on the same side for all the connections -
either - all of the connections must have the stripe next to the power connector on the drives and at the pin 1 end of the mboard header (it's marked with a 1 or an arrowhead or a triangle on the mboard surface) ,
- or - all of them must have the stripe on the other side.

Is there an option in cmos/bios setup to select IDE or SATA? If so, choose IDE.
