|There may be a hidden recovery partition on the hard drive, from which you can perform a Factory Recovery when Windows is broken (unless it's caused by faulty hardware):|
First you need to access the BIOS Setup utility by pressing <F2> at the Acer logo splash-screen.
In BIOS Setup, click the Main category.
Find D2D Recovery at the bottom of the screen.
Use <F5> and <F6> keys to set that feature to Enabled.
Save and Exit the BIOS Setup utility.
