Restore Factory Settings with Acer Recovery Management
1. Click Restore Factory Settings.
Caution: 'Restore Factory Settings' will erase all files on your
hard drive.
2. If your computer is configured with two operating systems (only
available on certain systems), a window opens with the option to restore
either Windows 7 or Windows 8. If you choose Windows 7, your
computer will restart and restore Windows 7. If you choose Windows 8,
Reset your PC opens, as described below.
Note: To fully enjoy Windows 8 features after changing from Windows
7, enter the BIOS (press <F2> when starting your computer) and
change Boot Mode to UEFI. If you reinstall Windows 7, you must
change Boot Mode back to Legacy before restarting your computer.
