Step 3. When the computer restarts, select the alternate Windows installation from the dual-boot menu.
Step 4. Find the logon.scr file. It should be located in the %systemroot%\System32 folder of the Windows folder.
Step 5. Rename logon.scr and move it into the C: folder of the hard drive. You can choose to move it to a different directory. The important thing is to remember where the file gets copied.
Step 6. Find cmd.exe and make a copy of it in the %systemroot%\System32 folder. Move this file to the C: folder of your hard drive.

Step 12. Restart the computer in the original. From here you can remove the additional installation if desired. If the administrator installation alternatives are on a different drive or partition to reformat the hard disk or partition is the easiest way to achieve this goal.
