After searching and reading many doomsday comments about this error message and what it means and what caused it, I found the simple solution with the Acer Aspire One ZG-5 mini-laptop displaying the "A disk read error occured... Press Ctrl+Alt+Del to restart" error message, the probable simple solution is to Press Alt+F10 during reboot and the laptop will go into the Acer eRecovery mode.
IMPORTANT NOTES:
-
It may or may not ask for a password or require creating a password, this password will be required to use eRecovery in the future. If you forget this step, you will need the recovery disks in the future to reformat the system.
-
Also please note that depending upon the options you choose you may lose any data on the computer because it restores the original operating system as the computer came out of the box.
-
Also, because restoring or recovery is a lengthyprocess you will need to plug the computer into the AC power supply.
Follow the instructions as they appear on the screen to restore or recover the operating system.
Also, it is a good idea once you have restored or recovered the operating system to go on the Acer website and download any patches or updates available.
Hope this helps.
