I have tried to install Windows 7 Beta multiple times, but I always get the following error statement while copying temporary files or just as "Setup is starting" is displayed: "Windows Setup experienced an unexpected error. To install Windows, restart t

Restarting the installation results in the same error message. Any ideas on what's wrong? Here are some details:
my computer is lenovo g585.
I am running windows8. It's licence will be closed in one week.
I have windows7 OS genune.
While installing this (with sandisk pendrive ) the unexpected error occurs.
I am using avast antivirus, I have turned off this while installing.
 So any help or suggestions would be greatly appreciated!
Thanks in advance!

Is OS already installed on your HDD?
