Testing your knowledge

Yesterday i bought a laptop with pre-installed vista. I started the computer and it begun to install vista. all the sudden, power goes off, fuckin up the install process. now, every time i start it up, it complains about an unexpected error, whitch prevents the install to go further. can anything be done with it? back up cd´s are in the hard drive of the computer, so i cant get them out and the machines own hard drive fixing program doesn´t fix the problem.

My knowledge test truly sucks, i admit, but do you think i meant that my house had a power blackout? I meant the battery. Ok, here it comes again for the ones who didn´t understand the first text.  Installation progress sucked off the battery power, shutting down the laptop in the middle of OS install.
