You are here:  Tutorials > How to create MS-DOS bootable USB drive?


poweriso can create dos bootable usb flash drive, which allow you to boot dos from usb drive. both ms-dos and freedos are supported. 

Diskcopy.dll is required to create MS-DOS bootable USB drive. However, the dll is removed from Windows 10. You can copy the dll from Windows 7 system directory. The dll should be copied to PowerISO installation directory.

Step1: Create MS-DOS Bootable USB Drive

  1. Start PowerISO (v7.5 or newer version, download here).

  2. 一分快三平台计划insert the usb drive you intend to boot from.

  3. Choose the menu "Tools > Create Bootable USB Drive". 



    If you are using Windows Vista or above operating system, you need confirm the UAC dialog box to continue.


  4. The "Create Bootable USB Drive" dialog will popup. Click Down-Arrow button, and select "More selection..." from the popup menu.

  5. The "Select source for creating bootable USB drive" dialog box shows. Select the option "Create MS-DOS bootable USB drive" and click "OK" button to close the dialog box.

  6. Select the correct USB drive from the "Destination USB Drive" list if multiple USB drives are connected to the computer.

    Choose the proper writing method. "USB-HDD" is recommended.

    Click "Start" button to start creating msdos bootable USB drive.

  7. PowerISO will alert you that all data on USB drive will be destroyed. Click "OK" to continue.


  8. The program will start writing boot files to the USB drive, and showing the progress information. You should get the message "Writing USB drive completed successfully." after the operation completes.


If no errors occurred in the above process, you should now be all set to Boot MS-DOS from USB drive!

 

Step 2: Configuring the BIOS

you should now reboot and go into the bios configuration to boot from usb. instructions for doing so vary wildly from system to system, but generally entail the following:

  1. reboot the system.

  2. 一分快三平台计划while booting (before windows starts loading), get into the bios configuration screen by hitting something like f1, f2, delete or escape. hotkey instructions are generally provided on the screen.

  3. go to the section that contains your boot devices.

  4. with your usb drive plugged in, the usb drive should be listed. if it isnyang, your system might not support booting from usb. assuming that it is supported (as is the case with virtually all modern hardware), promote your usb drive to the primary boot device.

  5. exit from the bios configuration, saving all changes.

please notice that you can seriously screw up your system by providing incorrect bios settings!

 

Step 3: Booting MS-DOS from USB drive

assuming that you properly configured your bios and your usb drive supports booting,  ms-dos should now load. 

if it isnyang working, then double-check the following before making a scene:

  • Is your BIOS properly configured for booting from the USB device? (Is the USB device listed and does it have top priority?)

  • Have you correctly prepared the USB drive in step one? (Restart the procedure.)

  • Does your USB drive properly support being booted from? (Try another one!)
