Hi Sid,
it is never a good idea, to post a new question at the bottom of another, already answered and outdated thread.
Sure that installation stops during the update stage? Dependend from the amount of data, the speed of your Internet connection and the kind of updates applying all updates to a fresh installed server can take a long time.
If you dont want this during installation process, you can try to install WHS while disconnected from the Internet.
Best greetings from Germany
Olaf
