Go to the Run dialogue box on your Windows XP or other "legacy" operating system start menu and type "msconfig" (without the quotes). This will open the System Configuration Utility. Then go to the BOOT.INI tab and select "Check All Boot Paths".
This is automatic and all you need to do after this is select "OK" and "Apply". Do not select "Restart" at this point, but choose "Exit Without Restart" instead.
Next, you must delete the following files and folders from the root of your System drive or partition (Usually Drive C:\)
$RECYCLE.BIN
Boot (folder)
Boot.BAK
BOOTSECT.BAK
