This article describes how to set up a computer so that the user can go directly to Windows NT, Windows 95/98, or MS-DOS by making a selection from the Boot.ini, without any need for Windows 95/98 multiple boot support.
Windows 98 or Windows 95 should not be installed in the same partition as Windows NT; the shared Program Files folder can cause problems with interactions between Microsoft Internet Explorer and Microsoft Outlook Express on these operating systems.
Also, if you are using both FAT32 and NTFS volumes, the NTFS partition should be on a logical drive letter that preceeds the FAT32 partition drive letter. If this is set up the other way around, Windows NT will not find the boot partition (where the system files are located).
This information applies to x86 processors only.
Follow these steps to enable triple boot support:
The new switches, /win95dos and /win95, are needed so that Windows NT can emulate the multiple boot process of Windows 95/98.
This article contains information about using Windows NT with a configuration that has not been tested and is not supported by Microsoft. If the steps described in this article do not function properly, use a supported configuration.
If Windows NT is going to be on the same partitions as MS-DOS and/or Windows 95/98, the partition must be an MS-DOS partition. Windows 95/98 FAT 32 partitions will not work with MS-DOS and Windows NT.
Using NTFS or FAT32 partitions will require different partitions for each operation system. The ARC path in the Boot.ini file will need to be modified to reflect the different partitions.
