Having a bootable USB is very essential, especially if you want to finish installing Windows faster. Using a bootable USB to install an operating system (OS) not only makes installation faster, but also saves a DVD!
Creating or using a USB drive to install Windows operating systems is very easy if you follow the steps mentioned below.
If you plan to use a bootable USB to install Windows 10, Windows 8.1, Windows 7 or Vista, see our guides:
How to clean install Windows 10 from ISO
How to create a bootable UEFI USB from Windows 10
Back to Bootable USB guide, here we assume that you are using Vista, Windows 7, Windows 8 / 8.1 or Windows 10 to create your bootable USB.
Prepare the Windows 10/8/7 boot USB drive
Step 1: Insert your USB device (4GB + preferable) in the system and make a backup copy of all the USB data, since we are going to format the USB so that it is bootable.
Step 2: Open the raised command prompt. To do this, type CMD in the search field of the Start menu and press Ctrl + Shift + Enter. Alternatively, navigate to Start> All Programs> Accessories> right-click on Command Prompt and select run as administrator.
Step 3: When the command prompt opens, enter the following command:
DISKPART and press enter.
DISC LIST and press enter.
Once you enter the LIST DISK command, the disk number of your USB drive will be displayed. In the image below, the disk of my USB drive is not Disk 1.
Stage 4: In this step, you must enter all the commands below one by one and press enter. As these commands are self-explanatory, you can easily guess what these commands do.
SELECT DISC 1 (Replace DISC 1 with your disk number)
CREATE PRIMARY PARTITION
SELECT PARTITION 1
FORMAT FS = NTFS
(The formatting process may take a few seconds)
Do not close the command prompt, as we need to execute one more command in the next step. Just minimize it.
Step 5: Insert your Windows DVD into the optical drive and write down the letter of the optical drive and the USB media. I use here “re“As optical drive letter (DVD) and” H “as USB drive letter.
Step 6: Return to the command prompt and execute the following commands:
D: CD BOOT and press enter. Where “D” is the letter of your DVD drive.
CD BOOT and press enter to see the next message.
BOOTSECT.EXE / NT60 H:
(Where “H” is the letter of your USB drive)
Step 7: Copy the contents of the Windows DVD or the contents of the ISO file to the USB drive now.
You are done with your bootable USB. You can now use this bootable USB as a bootable DVD on any computer that comes with the USB boot function (most current motherboards support this function).
Note that this USB boot guide does not work if you are trying to make a USB boot on a Windows XP computer.
