I have tried to press alt & F10 at the first screen but it still goes to windows- my daughter in stalled windows 7 professional and it has managed to wipe internet connection off and all the acer erecovery management and everything acer from the computer I need to reset it to factory setting
I had the same issue with my Acer laptop. So as soon as I rebooted I continued to press F10 and that got me to the default restore to factory screen. I also used Alt + F10 and it worked also. It can be tricky to get it to work using the Alt + F10 or just F10 method but if you do not have the restore disks that is the only way I know how. So try just F10 and see if that works.
