That's not an error, itself.

You get that message when you boot your computer from an XP (or 2000) CD.
No Emulation = Windows 2000 and XP CDs don't emulate a floppy disk like many bootable disks do.They use a different method to make them bootable.

If the bios halts at that point, and/or if you don't, or if you do, see "Press any key to Boot from CD" or similar and the XP (or 2000) CD files will not load after that, THAT's the error.

That can be caused by.....

- the laser lens on the drive is "dirty".
Try using a laser lens cleaning CD in the drive, or if it's a laptop drive,eject the tray and when there's no disk on it, wipe off the obvious laser lens.

- there's a problem with the CD.
If the CD is scratched it may not read properly.
If it's an original CD, try booting from it on another computer.
If it's a copy of a Windows CD,
-if it's a "slipstreamed" CD it may not have been made properly - in that case it won't boot in any computer
- it may not read properly in a drive it was not made in, especially if it's not a CD-R disk. You could try booting from it on another computer, but it working in a different drive model than on your computer doesn't necessarily indicate it will work in your computer's drive.

- there's a problem with the drive you're trying to boot the CD from.
Try booting from a different bootable CD.
-if your computer has more than one optical drive, try the Windows CD in a different drive.
NOTE that some bioses will only boot bootable disks from the first drive the bios detects. In that case there is usually a list of optical drives in the bios - the drive you want to boot from must be listed first.

- if it's a desktop drive, there's a problem with the drive's data cable.

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 intermittent, 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.

80 wire data cables must have the proper end connector connected to the mboard IDE header - usually that's blue, but in any case it's the one farther from the middle connector on a 3 connector data cable.

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.

- the optical drive is defective - try a different optical drive if you have a desktop computer - borrow one for testing purposes if you can.
Or buy a new one.They're relatively cheap.

If it's a laptop, replacment optical drives are available on the web for a reasonable price.

(You usually cannot boot from the CD and load the XP or 2000 CD's files from a USB connected optical drive even if you can set the Boot Order or similar settings in the bios to boot from a USB connected drive because the CD contents cannot recognize most if not all USB optical drive models. If that's the case for the optical drive model, loading the XP 6 floppy set meant to be used for optical drives you can't boot a CD from will not allow you to load files from the CD either.)

- there's a problem with your ram that is causing the boot to halt.

See response 2 in this - try cleaning the contacts on the ram modules, and making sure the modules are properly seated:

For a laptop, or netbook, you must remove both its main battery and AC adapter before you do that.

For a brand name computer, see the Owner's or User's manual if you need to - how to remove or replace the ram is usually in that - it may already be in your installed programs. If you can't get into Windows, it may be on a disk that came with the computer, or you can go online and look at it or download it - it's in the downloads for your specific model.

For a generic desktop computer, see the mboard manual if you need to - how to remove or replace the ram is usually in that.

- there is a problem with the hard drive that is causing the boot to halt.

Try disconnecting the data cable at the hard drive to see what happens when you try to boot from the XP or 2000 CD.

Check your hard drive with the manufacturer's diagnostics.
See the latter part of response 1 in this:

If you don't have a floppy drive, you can get a CD image diagnostic utility from most hard drive manufacturer's web sites, but obviously you would need to make a burned CD, preferably a CD-R for best compatibility, on another computer if you need to.

Seagate's Seatools will test any brand of hard drive.
Do the long test.

The bootable Dos versions of SeaTools can be used even if Windows is not working properly.

If the hard drive itself tests okay, any data problems found can be fixed, one way or another.
