Reformatting and Repairing the Hard Disk
You may need to reformat and repartition your hard disk if:
- You have only one volume.
- You
have to install each operating system on a separate volume of your
computer so that each installation can retain its own files and
configuration information. - The boot volume is not formatted with the correct file system:
- If
you want to create a multiple-boot system by using Windows 95, Windows
98 or Windows Me along with Microsoft Windows XP, you have to format
the boot volume by using FAT16 because Windows 95, Windows 98 and
Windows Me do not support the NTFS file system. - If you want to
install Windows 95, Windows 98, or Windows Me with Windows NT 4.0,
Windows 2000, or Windows XP, you can format the boot volume by using
FAT16 because Windows NT 4.0 does not support the FAT32 file system. - If you want to create a multiple-boot system using Windows 98 or
Windows Me with Windows 2000, or Windows XP, you can format the boot
volume by using FAT32.
NOTE: If you format a
Windows NT 4.0, Windows 2000, or Windows XP volume with any file system
other than NTFS, you will lose all NTFS-specific features. This
includes some Windows XP features such as file system security,
Encrypting File System (EFS) settings, disk quotas, and Remote Storage.
Likewise, Windows 95, Windows 98, and Windows Me do not recognize an
NTFS partition and identify it as unknown. Therefore, if you format a
Windows 98 or Windows Me partition as FAT, and a Windows XP partition
as NTFS, any files on the NTFS partition will not be available or
visible if you try to access them while running Windows 98 or Windows
Me.

- Windows XP FAT, FAT32, NTFS
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. - 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.
- 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
To Create a Multiple-Boot System with Windows XP and MS-DOS, Windows 95, Windows 98, or Windows Me
NOTE:
You cannot install both Windows 95 and Windows 98 in a multiple-boot
configuration. Windows 98 is intended as an upgrade to Windows 95 and
it will try to use the same boot file.
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.
To create a multiple-boot system with Windows XP and MS-DOS, Windows 95, Windows 98 or Windows Me:
- Ensure that your hard disk is formatted with the correct file system.
- Install
the multiple operating systems into separate volumes, in the following
order: MS-DOS, Windows 95, Windows 98, Windows Me, and then Windows XP. - Do one of the following:
- If
you want a multiple-boot system with MS-DOS, Windows 95, Windows 98 or
Windows Me along with Windows XP, install MS-DOS, Windows 95, Windows
98 or Windows Me, and then install Windows XP. - If you want a
dual-boot system with only Windows 95, Windows 98 or Windows Me,
install Windows 95, Windows 98 or Windows Me, and then install Windows
XP.
- If
- Install each operating system according to the standard installation procedure.
To Create a Multiple-Boot System with Windows NT 4.0 and Windows XP
Using a multiple-boot system with both Windows NT 4.0 and Windows XP is
not recommended as a long-term solution. The NTFS update in Service
Pack 5 (SP5) for Windows NT 4.0 is provided only to help you evaluate
and upgrade to Windows XP.
To create a multiple-boot system with Windows NT 4.0 and Windows XP:
- Ensure that your hard disk is formatted with the correct file system.
- Install Windows NT 4.0 and apply SP5, and then install Windows XP to a separate volume.
- Install each operating system according to the standard installation procedure
NOTE:
If you intend to install more than one operating system consisting of
some combination of Windows NT 4.0, with either Windows 2000, or
Windows XP as the only installed operating systems, you must ensure
that you have installed SP5 for Windows NT 4.0. Windows XP
automatically upgrades any NTFS partitions that it finds on your system
to the version of NTFS that is used in Windows 2000 and Windows XP.
However, Windows NT 4.0 requires SP5 to read and write files on a
volume that is formatted with the version of NTFS used in Windows 2000
and Windows XP.
Installing Programs on More Than One Operating System
If you are installing programs on more than one operating system, you
have to treat each operating system as a separate entity. Any programs
and drivers that you want to use must be installed under each operating
system under which you want to use it. For example, if you want to use
Microsoft Word on the same computer under both Windows 98 and Windows
XP, you have to start Windows 98 and install Microsoft Word, and then,
you have to restart your computer under Windows XP and reinstall
Microsoft Word.
NOTE:
Windows 95 or Windows 98 might reconfigure hardware settings the first
time you use them, which may cause configuration problems when you
start Windows XP.
Specifying the Default Operating System for Startup
If you have more than one operating system on your computer, you can
set the operating system that you want to use as the default one for
when you start your computer:
- Click Start, click Control Panel, and then double-click System.
- On the Advanced tab, under Startup and Recovery, click Settings.
- Under
System startup, in the Default operating system list, click the
operating system that you want to start when you turn on or restart
your computer. - Select the Display list of operating systems for
check box, and then type the number of seconds for which you want the
list displayed before the default operating system starts automatically. - To
manually edit the boot options file, click Edit. Microsoft strongly
recommends that you do not modify the boot options file (Boot.ini),
because doing so may render your computer unusable.
