Just had to restore a Gateway ZH7 Netbook to its factory settings, since the administrator password was forgotten and no other Users had Administrator access.
1. Turn on the computer, then press Alt+F10 during startup. Gateway Recovery Management opens.
2. Click on Restore system from factory default.
3. Click on next. The hard drive’s original, factory-loaded contents are recovered. This process will take several minutes.
Caution: This process will erase all files on the hard drive.
