Method 3: Create Windows 10 Bootable USB from ISO Using CMD

This section will explore an alternative method to create a Windows 10 bootable USB from an ISO file using Command Prompt (CMD). Utilizing the capabilities of the command line interface empowers you to complete the given task without relying on external utilities. Presented here are detailed, sequential guidelines that will assist you in generating a bootable USB drive for Windows 10 by utilizing CMD:

Step 1: Search for the “Command Prompt” in the Windows search bar. When it appears, click “Run as administrator” to open the Command Prompt with admin privileges. In the Command Prompt, run the command “diskpart.”

Step 2: Afterward, type and run the command “list disk” to see all the drives connected to your computer. Ensure that your USB is connected to the computer and select it using the command “select disk X.” Here, the “X” is the disk number of your flash drive.

use the list disk command

Step 3: To format the flash drive and clear all partitions, run the “clean” command. Afterwards, run the command “convert mbr” to convert your USB drive to MBR format. Now, run “create partition primary” to create a primary partition on your flash drive.

execute convert mbr command

Step 4: After creating the primary partition, make it active by running the “active” command. The next part is to format the primary partition with FAT32 and give the label a name, for which you can use the following command:

format quick fs=fat32 label=”VMP” (Here, “VMP” is a label name that you can change according to your preferences)

use the active command

Step 5: Now, give the partition on the flash drive a label with the command “assign letter=”I.” Now run “list volume” to see your USB and “exit” to exit the diskpart. Afterwards, minimize the Command Prompt and download the Windows 10 ISO file.

exit diskpart

Step 6: Once the file is downloaded, double-click it to mount the image. Windows will auto-assign it a DVD letter. Now re-open the Command Prompt and run the following command to copy all files except the “install.wim” file from the newly mounted DVD drive:

robocopy D:\ I:\ /D /xf install.wim (Here, “D” is the DVD letter assigned to the mounted image, while “I” is your USB drive.”

copy all the required files

Step 7: The next part is to copy the “install.wim” file to the USB drive. However, this file is larger than 4GB, and your drive can’t store a single file of over 4GB due to FAT32 formatting. That’s why you will need to split the file into two files. Here is the command to split the file and store it on the USB drive:

Dism /Split-Image /ImageFile:D:\sources\install.wim /VMPFile:I:\sources\install.swm /FileSize:2500

split the file size

Step 8: When the command execution is complete, exit the Command Prompt. Now check your USB drive to ensure there are two “install.swm” files. Now, your USB is bootable, which you can use to install Windows 10.
