I just plugged my computer in and began to install windows vista however my peripherals were not working because I could not get the dongle for the printer and keyboard to work. So I hooked up my old keyboard and mouse and they would not work until I restarted the computer. once I restarted a dialogue box popped up saying that because installation was interrupted the computer would have to be restarted in order to restart installation. This dialogue box pops up every time I restart the computer. The computer did not come with an installation disk! What can I do to fix this problem?
