It is possible to make an MS-DOS bootable disk when running Windows if MS-DOS version 5.0 is being used on drive C. If a machine running Windows has any other version of MS-DOS installed, the error message "Incorrect DOS Version" will be returned when attempting the SYS or FORMAT A: /S commands.
Note: This information is specific to the Intel x86 hardware platform.
To create a bootable disk with Windows, use the followingprocedure:
- Log on to Windows using an account with Administrator privileges.
- Place a blank floppy disk in the drive A.
- Select File, choose Run from Program Manager's menu, type C:\DOS\COMMAND.COM, then choose OK. This will start a virtual MS-DOS machine (VDM). The copy of COMMAND.COM in the MS-DOS directory must be used.
- From the MS-DOS directory (C:\DOS), type the FORMAT A: /S command.
- To boot from the disk, a valid COMMAND.COM must be copied to it. Use File Manager or the VDM to copy the correct version of COMMAND.COM from the C:\DOS directory to the floppy disk. COMMAND.COM should have the following attributes:
Size = 47845 Date = 4-9-91 Time = 5:00 am for version 5.0 Size = 47895 Date = 11-11-91 Time = 5:00 am for version 5.0a
If a valid COMMAND.COM is not copied to the floppy disk and youattempt to boot from it, the system will hang. An incorrect copy ofCOMMAND.COM is copied to the floppy disk by Windows during theformat. This copy is located in the \WINNT\SYSTEM32 directory. Theincorrect copy will have these attributes:
Size = 49931 Date = 7-24-93 Time = 5:11 am
