I beleive you have more of a hardware problem. This kind of error usualy only occurs when your hard drive is corupt, or is not recognised properly by your BIOS.
I suggest, first, using a Windows 98/ME bootdisk, if you have one available to you. The bootdisks from those systems actualy load a version of DOS into your RAM, which I have found to be quite useful, especialy since they also load CD-ROM support.
From DOS, after using the bootdisk, you can try reinstalling Windows 2000. You will need four formatted floppy disks to make the windows 2000 instalation bootdisks which are required for installation from DOS.
An earlier post mentioned using DEL or F10 to access the BIOS - although this may not apply to you, PhoenixBIOS is usually accessed by pressing F2.
Go to AllBootDisks.com and to BootDisk.com.
There are a number of possible solutions and disk images listed there.
