Dual-boot configurations between the personal operating system platforms (Windows Me, Windows 98 Second Edition, Windows 98, Windows 95 OEM versions, and Windows 95) are not supported. For example, Windows Me and Windows 98 cannot be installed on the same computer and you cannot boot from one personal operating system to another. These operating systems share the same Io.sys, Msdos.sys, and Command.com files. Also, multiple-boot configurations of Windows NT, Windows 2000, and a personal operating system, for example, Windows Me or Windows 98, are not supported.

You must install each operating system, for example, Windows 98 and Windows 2000, on a different partition. Multiple operating systems on the same partition are not supported.

It is recommended that you install your personal operating system first, for example, Windows 98 or Windows Me, and then install Windows NT or Windows 2000. This step ensures that the Windows NT or Windows 2000 boot sector is not overwritten.

The boot partition of a dual-boot configured computer must use the FAT16 file system, unless you are installing Windows Me, Windows 98 Second Edition, or Windows 98 and Windows 2000 on the same computer. In this case, the boot partition can be FAT32. If you are configuring any combination other than Windows 2000 and Windows Me, Windows 98 Second Edition, or Windows 98, and the boot partition is either FAT32 or NTFS file system, you must back up your data, and then format and repartition your hard disk to FAT16 before you set up a dual-boot computer.
