Here is an alternative to using a disk.

Keep pressing the “F8” key until the “Advanced Boot Options” menu appears.

Use the arrow keys to navigate to the “Safe Mode” selection on the “Advanced Boot Options” menu. The arrow keys are located on the right-hand side of the Acer Aspire keyboard.

Press the “Enter” key to execute the “Safe Mode” selection. The Windows operating system will now start in “Safe Mode” and you can perform a system restore or make needed changes to get your Acer Aspire to boot normally again.

Hope this helps!
