How To Make Bootable USB Through CMD

 

Having a bootable USB is very essential, especially if you are a Netbook user. Using bootable USB to install an operating system (OS) not only makes the installation faster, but also saves a DVD.

Creating or using an USB drive to install Windows operating systems is very easy if you follow the below mentioned steps:

Note that this bootable USB guide will not work if you are trying to make a bootable USB on XP computer.

Coming back to bootable USB guide, here we assume that you are using either Vista or Windows 7 to create a bootable USB.

1. Insert your USB (4GB+ preferable) stick to the system and backup all the data from the USB as we are going to format the USB to make it as bootable.

2. Open elevated Command Prompt. To do this, type in CMD in Start menu search field and hitCtrl + Shift + Enter. Alternatively, navigate to Start > All programs >Accessories > right click on Command Prompt and select run as administrator.

3. When the Command Prompt opens, enter the following command:

DISKPART and hit enter.

LIST DISK and hit enter.

Once you enter the LIST DISK command, it will show the disk number of your USB drive. In the below image my USB drive disk no is Disk 2.

4. In this step you need to enter all the below commands one by one and hit enter. As these commands are self explanatory, you can easily guess what these commands do.

SELECT DISK 2

CLEAN

CREATE PARTITION PRIMARY

SELECT PARTITION

ACTIVE

FORMAT FS=NTFS

(Format process may take few seconds)

ASSIGN

EXIT

 

Don’t close the command prompt as we need to execute one more command at the next step. Just minimize it.

5. Insert your Windows DVD in the optical drive and note down the drive letter of the optical drive and USB media. Here I use “J” as my optical (DVD) drive letter and “M” as my USB drive letter.

6. Go back to command prompt and execute the following commands:

J:CD BOOT and hit enter. Where “J” is your DVD drive letter.

CD BOOT and hit enter to see the below message.

BOOTSECT.EXE/NT60 M:

(Where “M” is your USB drive letter)

 

7. Copy Windows DVD contents to USB.

You are done with your bootable USB. You can now use this bootable USB as bootable DVD on any computer that comes with USB boot feature (most of the current motherboards support this feature).

Note: If you are not able to boot after following this guide means you haven’t set the BIOS priority to USB. If you got any problem in following this guide feel free to ask questions by leaving comment.

These days the technology is changing very rapidly and with in a short span of time we have to update with the new patches ans supplement for several software, though these are always in the favor of the end user but most of the time we just don’t want to implement these latest changes.

To do so go to windows run command (Using windows key +R) and then, typeregedit to open Registry Editor And Click on the HKEY_LOCAL_MACHINE.

 

 

So now you have registry editor opened then only browse to the following key:

Control>Windows

Double Click on the CSDVersion that is on the Right side
