Instructions for how to make a bootable drive using windows command line.
Creating the Bootable Windows 10 USB Drive
First, I will explain how you can manually create a bootable Windows 10 USB drive. Here is where the archiving tool comes in handy, as you will have to use it to extract the contents of the ISO in a folder on your Windows PC. After this is complete, plug in the USB drive and follow the next steps to create the installation media:
- Open a Command Prompt window. To do this, open Run (Windows key + R will do the trick; alternatively, it can be found in the Start menu), type "cmd" and then press the OK button.
- Use the "diskpart" command to open the disk partitioning software. Accept the UAC prompt, if asked, to continue.
- Use the "listdisk" command to display the list of storage drives -- it will reveal all the HDDs, SSDs, USB drives, and so on, that are attached to your PC.
- Identify the disk number of the USB drive that you are using -- you can easily find it by looking at the size column; it is usually the last one that is listed.
- Use the "select disk X" command to select the USB drive -- "X" is the disk number of your USB drive, and it is shown in the first column.
- Use the "clean" command to erase everything on the USB drive.
- Use the "create partition primary" command to create a primary partition on the USB drive.
- Use the "select partition 1" command to select that partition.
- Use the "active" command to make said partition active.
- Use the "format fs=fat32 quick" command to format it as FAT32, using the Quick (fast) routine.
- Use the "assign" command to assign a drive letter to the USB drive -- it will show up as a drive under My Computer.
- Copy the extracted contents of the Windows 10 ISO to the USB drive
