Dual-booting all versions of Windows and Linux
Menu: Natural Dual-Boot of MS-DOS 6.22 and Windows 7
Last reviewed: Feb 2012
These guides will show how to create a natural dual-boot of MS-DOS 6.22 and Windows 7 on the same computer. You can then select either operating system from a menu when booting up your computer.
There are two methods by which you can setup the dual-boot. One is to move the existing Windows 7 partition to leave room for MS-DOS 622 at the start of the disk. The other is to wipe the existing Windows 7 partition clean, repartition and install Windows 7 again.
In all methods MS-DOS 6.22 must be installed on the start of the first primary partition of the first hard disk.
Dual-Boot Windows 7 and MS-DOS 6.22
#1 by moving Windows 7
This method uses the free GParted Live CD to move the Windows 7 drive to the right, leaving not greater than 2GB free at the start of the first hard disk.
It does maintain the integrity of your Windows 7 and software installations. However, moving a large partition can be extremely slow. Also, there's a very small risk of an error during the moving process - never encountered by THPC!

#2 by clean installing Windows 7.
Here the Windows 7 partition(s) are wiped clean and a fresh Windows 7 is installed on a second or third primary partition of the first hard disk. The new partitions are created by Windows 7 during the installation.
This method deletes all of the Windows 7 partition and requires a serious backup of all important data, passwords, personal items, etc., before you begin. A full Windows installation DVD is essential - a Recovery or Restore disk will not work. However, it's easier and relatively quick to setup and produces a new clean system.
