Aye, RayRaz has the right of it... Are you using XP Pro or XP Home? The fact that you can even get into XP boot options means that not ALL of the data on the system has been damaged, hopefully it's only the boot sectors and in that case all you really need to do is get it to launch XP Setup. Once that happens, either it will launch into XP, although many of the setting may revert to stock, but your data, registry, and programs should remain intact. My point it, your files are more than likely NOT yet lost! Good luck, Zhann, and in the future stay away from proprietary boxes and get yourself an Uninterruptible Power Supply, they are fairly cheap and even the worst ones will give you a good half hour to shut down your PC before things go awry... (whatever you do, just don't format your drive yet! There may still be hope...)
