How To Create Bootable USB/Pen-drive Without Any Software (Any Windows)

    

                In this Era, very few people who burn ISO images on disks. And use them as bootable media. Now, USB drives have replaced them. As they are faster and a more convenient method to install an operating system on a machine.

    There are many tools available on the internet to make a bootable USB drive. There’s one provided by even MICROSOFT. There’s a way to do the same without any software.  All you need to do is launch Command Prompt and follow some simple instructions. Here are step by step process to create a bootable USB drive as the Windows installation media. To create a bootable USB drive as a Windows installation media, we require at least 4 GB for minimum capacity because larger capacity is better.

Let’s take a look at it……..

Step 1

1)-Insert your USB drive into your computer.
2)-Open Start Menu and type CMD to find Command Prompt. Right-click on Command Prompt and click Run as Administrator.
3)-Once the Command Prompt window appears, type diskpart and hit enter. Wait until the diskpart utility starts running.

           

4)-In the new diskpart window, type list disk and hit enter. It will show you all active disks on your computer.

           

Most probably, you will see two Disk types.

Disk 0 is for the hard drive and.

Disk 1 is for your USB Drive with its total capacity.

5)-As we are going to work on creating bootable USB using CMD, we will work with Disk 1.

Type select disk 1 in the same window and hit Enter. 

You will see a message ‘Disk 1 is now the selected disk’. 

It means any further operation that you do will affect your disk 1 directly.

6)-Type clean and hit Enter to remove all of the data in the USB drive. 

Clean command will format your bootable drive. 

You will see a message like ‘Diskpart succeeded in cleaning the disk’.

7)-Type create partition primary and hit Enter. 

Create command will create a primary partition.  

It recognized by Windows as 'partition 1'.

You will see a message like Diskpart succeeded in creating the specified partition.

9)-Type select partition 1 and hit Enter. 

It will choose partition 1 for setting up it as an active partition.

You will see a message like Partition 1 is now the selected partition.

10)-Type active and hit Enter. 

It will activate the current partition.

You will see a message like Diskpart marked the current partition as active.

11)-Type format fs=ntfs quick and hit Enter. 

This command will format your current partition as NTFS file system quickly.

You will see a message like Diskpart successfully formatted the volume.

12)-Type exit and hit Enter. 

The exit command will close the Diskpart program 

But it doesn’t close the CMD window.

Step 2

        Now there are two Methods to copying Windows installation files to USB Drive.

1)-Copying Windows installation files from an ISO image on your PC/DVD to bootable USB manually.

2)-Copying Windows installation files from an ISO image on your PC/DVD to bootable USB by using Command Prompt.

Method 1

Step - 1

1. Copying Windows installation files from an ISO image on your PC/DVD to bootable USB manually.
2. As here we are working on an ISO File. So, First, we Mount ISO File.
3. Now all you need to do open the files inside the DVD or ISO, copy them and paste inside USB storage manually. 

       

Step 2: Creating a Boot Sector

1. Let assume that the USB drive is the G: drive.
2. And the DVD/ISO installer located on drive H:
3. In the first step, we will navigate Command Prompt to set installation DVD/ISO as its active directory.
4. By default, Command Prompt's active directory for Administrator permission is on C:\Windows\System32>. 
5. We will navigate Command Prompt to set on DVD/ISO (H:) as its active directory. 
6. Just type 'h:' then hit Enter.
7. The active directory changed to H:.

     

    8. Type 'cd boot' and hit Enter. Active directory changed to H:\boot>.

   

    9. Type 'bootsect /nt60 g:' and hit Enter.

    10. Creating a boot sector on G: drive (USB flash drive).

    11. You will see a message Boot code was successfully updated on all targeted volumes.

   

    12. The last step of this method is Type 'exit' and hit Enter to close the Command Prompt.

    13. Until this step, we have made a bootable USB drive successfully.

     The flash drive is ready to be used as a boot media.

Method 2

• Copying Windows installation files from an ISO image on your PC/DVD to bootable USB by using Command Prompt.
• As here we are working on an ISO File. So, First, we Mount ISO File.

      

Step 1: Creating a Boot Sector

1. Let assume that the USB drive is the G: drive.
2. And the DVD/ISO installer located on drive H:
3. In the first step, we will navigate Command Prompt to set installation DVD/ISO as its active directory.
4. By default, Command Prompt's active directory for Administrator permission is on C:\Windows\System32>. 
5. We will navigate Command Prompt to set on DVD/ISO (H:) as its active directory. 
6. Just type 'h:' then hit Enter.
7. The active directory changed to H:.

       

      8. Type 'cd boot' and hit Enter. Active directory changed to H:\boot>.

      

    9. Type 'bootsect /nt60 g:' and hit Enter.

    10. Creating a boot sector on G: drive (USB flash drive).

    11. You will see a message Boot code was successfully updated on all targeted volumes.

    

    12. The last step of this method is Type 'exit' and hit Enter to close the Command Prompt.

    Until this step, we have made a bootable USB drive successfully.

Step 2: Copying Installation Files

1. To install Windows from a bootable USB drive, we just need to copy the whole installation files contained on the DVD/ISO installer to flash drive. 
2. To do this, open the Command Prompt as in previous steps. 
3. Once it opens, type 
4.  xcopy H: \ *. * G: \ / E / F / H and then press Enter. 

      

    5. Wait until all the files in the DVD/ISO installer copied to the flash drive. 

    Now bootable USB drive is ready to be used for installing Windows from the flash drive.
