Verify that the Boot Disk is in the
drive, then press the computer ``reset'' button or turn the
power off and on.
At the Boot:
prompt, press <Enter> to
start the installation again from the beginning.
If you stop the installation after the software starts loading,
the previous system cannot reliably be restored.
If the previous system is not restored, the Upgrade
installation type and the Preserve disk layout option
may not be available in the restarted installation, even though
they were available in the first (aborted) installation.
