Yeasterday I have bought a new notebook ( HP Pavilion dv6000) with windows vista in it already, without the cd. During the installation the power was cut off. When I turned the computer on again there was an error: the installation can not be finished. Please reboot the computer and reinstall Vista. But when I reboot nothing happens and the error appears again. What am I suppose to do? Is there any way to start the instalation again? I can't give it back to the shop as I bought it in another city.
