How To Make Bootable USB

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.

here i 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 hit Ctrl + 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 1.

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 1 (Replace DISK 1 with your disk number)
• CLEAN
• CREATE PARTITION PRIMARY
• SELECT PARTITION 1
• 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 “D” as my optical (DVD) drive letter and “H” as my USB drive letter.

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

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

CD BOOT and hit enter to see the below message.

BOOTSECT.EXE/NT60 H:

(Where “H” 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 that this bootable USB guide will not work if you are trying to make a bootable USB on XP computer.

BIOS SETUP:

You need to change the boot-up setting in the system BIOS as described below to boot using your portable device:

1. With your device inserted, restart the machine.
2. Enter the BIOS setup menu to change the boot device setting.
3. If the boot-up files are created in the USB drive, select USB-HDD or USB-ZIP (preferred). If the boot-up files are created in the floppy drive of your device, select USB-FDD (for Pen Drive that supports SECURITY mode).

8. Save and exit the BIOS setup. You should be able to boot up with you USB device.
