Hi everyone. My friend has an acer laptop. He wants to replace the hard drive in it because it no longer works because it was dropped. Its got Vista on it an im guessing a serial for it on the bottom of the laptop. The laptop came with no Vista CD so how would I install it new again on the new hard drive? I know how its all done but how do I get Vista? Can you download it for free an put in your own serial from the laptop or what? Anyone know anything, give me a shout. Thanks!
