You can make a bootable USB using the Windows command line. Creating a USB boot drive varies with different operating systems, so check with the instructions for your operating system if you use something other than Microsoft Windows.
- Prepare the boot drive
Insert the USB stick into a port on your Windows PC. Make sure the stick has enough space to boot your selected programs.
- Enter the command line
Open the Command Prompt window, and type "diskpart." When the new window opens, type "list disk" to determine the USB drive number or letter.
- Continue using Command Prompt
Note the USB drive number and letter. Type "select disk (X)" with "X" representing the number or letter of the USB drive. Press Enter. Type "clean," and press Enter to delete all data on the USB drive.
- Create and format a partition
Type "create part pri," and press Enter to create a new partition. Type "select part 1," and press Enter to select the newly created partition. Type "format fs=ntfs quick," and press Enter to format the new partition.
- Finish the process
After you create the partition, type "active," and press Enter. Type "exit," and press Enter. Save your custom image to the USB root folder.
