This forum does not provide support for the retail Norton Ghost product - the sticky posting at the top of this forum will direct you to the Norton Community.

Alternatively, the free imagex utility provided with WinPE may be something worth trying if you want to spend some time getting familiar with WinPE operations. The following article may help:
