Precautions Before creating a multiple-boot configuration with Windows XP and another operating system, review the following precautions: Before attempting to create a multiple-boot system, be sure to back up your current system and all data files. Each operating system must be installed on a separate volume. Microsoft does not support installing multiple operating systems on the same volume.
50. If you have only one volume on your computer, you have to reformat and repartition your hard disk to contain multiple volumes before you begin creating a multiple-boot configuration, unless you are simply installing another copy of Windows XP. Do not install Windows XP on a compressed drive that was not compressed using the NTFS compression utility.
51. You have to use a different computer name for each operating system if the computer is on a Windows 2000 or Windows XP secure domain. Install the operating systems in the following order: MS-DOS Windows 95, Windows 98 or Windows Me Windows NT Windows 2000 Windows XP
52. NoteYou can only install a single instance of Windows 95, Windows 98, or Windows Me in a multiple-boot configuration. You cannot configure a computer to multiple-boot Windows 95, Windows 98, or Windows Me because each of these platforms use the same boot file. For example, you can use Windows 95, Windows 2000, and Windows XP, but you cannot use Windows 95, Windows 98, and Windows XP.You have to install Windows XP only after installing MS-DOS, Windows 95, Windows 98, or Windows Me to prevent these operating systems from overwriting the Windows XP boot sector and the Windows XP startup files.
