Presumably often help students install system technology men have encountered this problem: for Acer if the system tray reinstall, the traditional method is fruitless (guide simply write not to go in, so the total card in the first step as follows figure I)! Someone on the internet said: Acer wonderful, to the whole can rebuild the main guide. Of course I have not tried, after all, this is too much trouble (good hundreds of g)! Churn for a few hours finally solution, I was so resolved: After entering PE with ghost to restore the ISO, of course, the target letter for the default C, this process will report some inexplicable mistakes, do not care about it. When found in C disk file Bootmgr file, restart the computer into our regular second step. The second step is simple, needless to say.
Although I do not know why, but this can be successful, hope can help everyone!
Dear God, if there is any other good way to exchange it! It's not too early to wash and sleep
