You will need to use rsync to copy a mirror to one computer and install from there
or
make a nfs server as the install media.
Corrupt data? Torrent download? If yes and still corrupt, try tao or sao for writing. If no, then download the md5 sum and compare it as the program reads the image.
Double check the md5 sum and do a verify. Because of such, I use cd-rw media for safe burning.
Qemu and virtual box are two programs that can also test image integrity.
Another method is to buy a book with the media included.
Can I down load this to the desk top and install it from there? How about USB? What file do I open to make it install the USB way? I could set up a LAN and install it from another PC. What is the easiest route? Simplicity please! I'm not really interested in becoming a Linux installer guru.
