For both search engines and those who may have similar problems, when I was running my Vista Home Premium Upgrade as a clean install, I kept on getting an Error 0x8007048F after the partitions screen, where you choose to install Vista at.
It got to around 3%, sometimes a little more, and it gave me this error. Microsoft had no documentation of this Error before, oddly. It said something to the extent of missing files, make sure they are availible and try the installation again. I called Microsoft, and they had me give them the error word by word, as this has never happened before.
Long story short- it was happening because my second hard drive was not plugged in and installed on it. It shouldn't matter- and even Microsoft wasn't sure why, but it may have had bad sectors on it (Although after the install it worked fine).
After installation, Microsoft actually issued me a full version product key to activate Vista with, so I wouldn't have to start the installation again within Vista (remember, this was an upgrade of Vista and not a full verion). They could've just left me with the Upgrade workaround (they frowned upon it actually), but they issued me a new key!
