The most hassle-free way to format your Acer Aspire One is through the built-in eRecovery software. This application exists within a hidden partition on your computer's hard drive along with a pristine copy of Windows. When you invoke this program, it will clear most of your hard drive and install a fresh copy of Windows to it. You can effectively reset your computer to the condition it was in when you first turned it on.

1. Connect the Aspire One's power adapter to the computer, and plug it into the wall.

2. Turn the computer off by clicking "Start" and then "Shut down."

3. Press the Power button. After 20 seconds, press and hold the "Alt" key and then tap "F10" repeatedly as your computer boots up.

4. Release the "Alt" key when the "Starting Acer eRecovery" screen appears.

5. Press the "1" key to select the "Restore system to factory default" option.

6. Enter your eRecovery password in the space provided, and press "Enter."

7. Read the Acer eRecovery terms and conditions, and then click the "Yes" button to signify that you understand and agree.

8. Click "Next" to initiate the formatting process.

9. Follow the step-by-step setup process for Windows that begins after the unit restarts.

I hope you find it very helpful.

2. select Main from the categories listed at the top of the screen

Alternatively to the above, if Windows can be accessed, the recovery can be done by launching Acer eRecovery Management by running the program from the Acer Empowering Technology program group in the Start menu.
