I am sorry that I have so many questions here about getting my acer laptop back up and running. I burned a cd with killdisk, put it in laptop, turned it on, it said that it was starting windows, set up was preparing computer for first use, then a box pops up that says "the computer restarted unexpectedly or encountered an unexpected error, windows installation can not proceed. to install windows, click ok to restart the computer and then restart the installlation." No matter what i do this is what I endup with and can't get any farther. When I turn on the computer it does this even with no disk in. Can you help me by tellling mestep by step on what to do?
