The errors you were getting were probably due to the quality of your install disk or cdrom, it should give you the option to retry whenever it cant find a file when installing a recent OS. You should always try to retry, if it doesnt work after the 2nd time, try sticking in another OS cd (they usually have similiar files and its just looking for the file, not for the CD). The more recent the OS the better chance you will have of it finding the file. I had to do this with a highly damaged copy of windows server 2003, i used an emergy disc for XP, a windows xp pro and windows xp cd in conjunction and it finally got all the files it needed :D. Just have to be patient.
