win 2000 emergency repair disk

[HondaF1]

hi, my win 2000 installation has come across a boto error or something, some corrupt or missing file, but it shows a directory. I ncan use the installation cd's repair function, but need an Emergency Repair Disk for it to recognize the installation as I have XP Pro on my box too. I do not know where to get this Emergency Repair Disk, it is I believe supposed to be obtained from within win 2000, but now it wont boot, so what do i do help please.
