How old is the computer??  If Dex's advice doesn't work, you may have multiple issues 
and need a valid bootable floppy with the CD rom drivers on it.  We would have to 
know exactly the procedure you are using and exactly what kind of software/booting 
media you have to be of further help.  What type of W2K install disc do you have? 
 OEM, retail full or upgrade, MS original, copy of a disc etc etc.  Finally, an I/O 
error is almost always a hardware failure.  If it's not due to an external piece 
of hardware or drive/cabling, then IME it is a bad motherboard most likely..
