HOW TO MAKE FLASH DISK A BOOTABLE DISK

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. If you are planning to use bootable USB to install Windows 7 or Vista please refer our guides:

Install Windows 7/Vista using bootable USB guide
And also, you can refer install Windows 7 on Acer Aspire One
guide.

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 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.

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.
