it still brings up the original windows 2000 boot screen
This is some what normal on some systems, for me this happened on XP until SP3 installed.
which makes the image incorrect, colors messed up, and makes the boot look terrible.
If this is a bootskin you have created yourself I think you have image wrong. It must be a 640x480, 4 bit 16 color image, if you are using a progress bar it must have the exact same color palette as the screen image.
Here is a good tut for bootskins.
