Press the Arcade button again with the laptop off, but DON'T interrupt it. The situation can hardly become worse than it is now, I'd say.
But wait a day to see if somebody comes with a better idea!
I have an Acer Aspire 5920G laptop with Windows Vista.
When the laptop was off, I accidently pressed Acer Arcade button. All of a sudden the laptop tured on and started installing something, so I turned it off quickly.
Now whenever I turn the laptop back on, it seems to have lost the Operating System (Windows Vista) and shows a Vista background with a window called System Recovery Option with an area to show list of operating system. I can't find any operating system on it. I could just cick next and click on system restore, but will not system restore either. There is an otion to click the command prompt. But I don't know what to type in it etc.
Can somebody please help me.
