Used Ghost 15 to copy system hard drive, then disconnected old drive to boot from new replacement hard drive. Boot seemed OK, but paused long time on "preparing your desktop" and then went blue screen with corner note "this copy of windows not genuine" and only task manager accessible with ctl-alt-del command. CD repair would not work to correct boot.to blue screen. Stated "unabble to repair the difficulty with startup, do you wish to report difficulty?" Any clues how to get the Windows 7 to run and not be labeled as not genuine when it is genuine. It is however a copy of the genuine Windows 7, but not trying to use both sumultaneously or even have both old and new disk attached to the motherboard.
