Adding a Test Entry in Boot Menu dialog box
Once you clone the current working system volume (typically,
C:) into a backup volume, you should be able to use the new
volume to boot your computer into a Windows environment.
You may do so without removing the current system volume from
the computer, or even swapping the disks.
The text box labeled "Appearance in the Boot Menu" in the
dialog box provides a suggested text for the visible part
in the line that you may change to fit your taste.
When you click the OK button, the BOOT.INI file will
be modified with the additional entry that will appear in the
the boot menu in the next boot process.
After the BOOT.INI file is changed, you will find the new
entry you added through this dialog box displayed in the
boot menu. Selecting the Target volume in the boot menu
will instruct the boot procedure to use the specified volume.
If you have a problem in booting into the newly cloned volume,
you should consult the Troubleshooting
