There are many types of software and tricks to make bootable pen drive for windows installation.
Some tricks are based on software tools and some tricks are based on command prompt.
Here i am providing you to a simple and safe trick for make a bootable pen drive.
First you should have an Iso image file or installation media of windows 7 or 8 for this trick.
Lets go on the trick:
Step:1
First pluged in your USB Pen drive in computer.
Now open CMD .
Note: If you are using Windows 7/Vista or 8 then open it with administrative rights.
Step:2
Now type following command in command prompt
DISKPART
Now type the following command.
LIST DISK
Then you can see a list of available disks on your system. Disk 0 is usually the hard disk. In my
case, Disk 1 is the USB drive (this can be a different one in your case).
Then type the following command
SELECT DISK 1
In the above command, 1 is the USB drive number on my Computer. If you have a different
number on your Computer, then you need to replace 1 with that number.
Step-3: Then type following list of commands one by one as shown below.
CLEAN
CREATE PARTITION PRIMARY
SELECT PARTITION 1
ACTIVE
FORMAT FS=NTFS QUICK
ASSIGN
EXIT
Step 4: Insert the Windows 7/Vista or 8 installation media and note down the “drive letter”
of your DVD drive. In my case, “G:”
I have installed power iso so i have an virtul drive for mount ISO file
Now again open cmd with administrative rights
Now type the following list of commands as shown below.
Note: If you have Windows ISO file, then mount it to virtual drive . Then in the bellow
command, instead of goto drive’ H:’, Using command prompt, Goto the folder in which you
extract windows ISO files. Then goto BOOT folder inside the folder that contains your
extracted ISO file as bellow.
G:
CD BOOT
BOOTSECT.EXE /NT60 H: (NOTE: H: is your USB drive letter and G: is DVD).
EXIT
This process will copy boot files from DVD to your Pen drive.Now your pen drive is bootable.
Step-5: Copy the contents of your Windows 7/Vista installation disk (or content of your extracted ISO files) into the Pen drive drive as it is. You can directly Copy-Paste all file into Pen drive
Dont forget to change boot priority to USB drive
