If your computer doesn't have an operating system installed, you can start your system with MS-DOS Upgrade Disk 1, but Setup won't run.


The MS-DOS Upgrade Setup Disk 1 is always bootable. In other words, The Setup Disk can be used to start up a computer if the hard disk drive is inaccessible, cannot be booted, or does not contain an operating system.

However, the MS-DOS 6 Upgrade and later Setup programs do not run if there is no operating system on the computer. The MS-DOS Upgrade package is licensed, sold, and designed for users who have an existing copy of MS-DOS (or some other operating system) and who want to upgrade to MS-DOS 6.0 or later.


If your computer does not have an operating system installed, and you don't have your original operating system disks, you need to contact your computer manufacturer to obtain a copy of its original equipment manufacturer (OEM) version of Microsoft MS-DOS 6.2.
