you have partly or maybe even entirely destroyed your boot files and other files, which means you have most likely lost vista components.. so really you can only reinstall vista.. if you have a disc you can use that, or if not, you will have to get a new copy..
the reason behind this is. when windows is shuting down, it needs to save files and settings for the next boot-up. but when the battery is removed from a laptop or there is a power failure, it has no chance to save it, and approximatly 2 out of 10 times removing the battery/power outage, something will go wrong with your computer, just like in your case, it seems you have lost components of vista...
you could try contacting microsoft support, and give them you KEY (vista serial number on the side of you machine) and see if they can send you a replacement install disc (chances are, there will be a charge + p&p)... but if not, you will have to purchase a new installation disc..
