my acer aspire one turns on and printed on bottom says setup service or something close to that, then a white light flashes for a minute and it says was unable to set up windows, to set up windows restart computer or windows will be set up when you restart computer. There is a box to click ok and one to close this message, no matter what I choose it doesn't set up or load windows. I can access all the boot up options with <F10> & <F2>. What can I do? cant put in a disc there is no disc drive!
