Nope your console has to extract the files form the official update. You also have to run the update from a FAT32 formatted usb hard drive, i dont think you can do it off the internal hard drive.
Its been over 4 years since i did this, however i believe it will erase everything on the drive when you re-partition it.


Yes that's normal, you are only formatting the user data partition on the drive. The avatar / kinect data, along with the Xbox Classic emulator will not be erased.
