After the ghosting to a new PC process, I test ran that PC. When I work some settings or try software in Windows, sometimes or rarely PC sudden reboot. I use norton ghost 8.3 from hiren bootcd, which means I choose Norton Ghost 8.3 in Hiren menu, not in Windows XP or dos, so I don't know how to use -rb unless there is an option to be picked in the Norton Ghost. Oh yeah, I guess there is another thing may cause this problem, that is Windows XP inside the ghost image already has problem to cause PC reboot before I ghost. Because I noticed inside Windows's event viewer from Administrative Tools, it said that the computer has bugcheck and require reboot and mentioned the memory addresses. I guess I made mistake on installing Windows or hardware problem. haha... Why I don't figure it first. Shame on me. But anyway thanks you guys for helping me. Can you give some tips when I ghost Windows XP so I won't make mistakes again, thanks again.
