I actually stopped reading at this point, no reason to go any further. this is wrong in multiple ways. You don't extract anything from the ISO. You do not use the Nero Make Bootable option. Use the documentation link at the top of this page, then read the Downloading faq.

Additional hints: Check the md5 sum before you burn. This is really important. So what if you don't know what that means? Learn, then do it. Use a 700 meg CDRW if you have one for your first burns until you get it right. When burning a CDR do it at a low speed like 4x, not as fast as the burner claims it will go. No good reason why a burner that claims it can burn at 48x or faster doesn't burn well at those speeds, but we've seem plenty of cases where the burn speed was the final problem. You need to burn the ISO file as an "image", do not drag the iso into the file area and do not use "make bootable" options.
