I have purchased an Acer Laptop with a bootable windows 7 DVD and thus trying to install windows 7 strictly according to the steps given in Manual. According to the manual, Insert the windows 7 DVD, click on f12 and then choose “Boot from cd/dvd” but I am not getting this screen. Instead it redirects me to a screen which shows Windows Failed to Start. Do you have any Idea, what is happening? Is there any solution for the same?
