Battlefield 1942 and Vietnam disk problems?

So I recently decided to install Battlefield 1942 and Vietnam again, but when I try to do either one, it stops at disk two for both and says I am missing the specified media. And it's not the same disk, for 1942 it stops on disk 2 out of the 8 disk set, and Vietnam starts on disk 5, so disk two for that is disk 6. I have no idea what this problem is and I can't find it on Google other than the problem is my disk drive, or the disk itself, but I don't think that it's a coincidence that both of them won't work at disk 2 for them...

If this makes no sense let me know... But I would like to know if anyone else has had the problem...

And by the way, this problem is with the pack that comes with BF 1942, 1942: Road to Rome, 1942: Secret Weapons of WWII, and Vietnam... I don't want to go download 1942 from origin because it doesn't include RtR or SWoWWII (which is my favorite due to the mini plane).
