Make your pendrive,bootable...

Hi Guys,

There may be times when your CD-ROM does not work properly or may be you don't have a DVD to write the image of OS you need to install on your system.

So all you need to do is to have a 4GB pendrive and get started. Actually pendrive is flash memory so it installs faster than DVDs. enjoy!

(applicable for Win Vista and Win 7)

Step 1: First you need to format the pendrive or USB drive in NTFS format. This can be done by right clicking your pendrive icon and choosing format option.

Step 2: Now from the start menu right click on command prompt and choose "Run as administrator".

Step 3: Now type the following commands, hitting enter after each command
( ;) being more explanatory)
note:commands are not case-sensitive.

- diskpart .The disk part program windows will open.
- list disk .This will show the list of disks in your computer.
- Note down the disk number of your pendrive from the list eg. Disk 1.
- select disk 1 . If your pendrive is disk 1 in list
- clean
- CREATE PARTITION PRIMARY
- SELECT PARTITION 1
- ACTIVE
- FORMAT FS=NTFS . (be patient it takes some time)
- ASSIGN
- EXIT . (Now the disk partition program will exit)

Now we need to give some more commands.


Open the location where you have the image (.iso) file of the OS.
Open it with winrar.
Extract the BOOT folder to a convinient location . say C:\BOOT
Now goto command prompt and bring it to c:\boot>
If your pendrive letter is I: type this command - BOOTSECT.EXE/NT60 I:
to update your USB drive with bootmgr code.

Finally extract all the contents from the Windows Vista/7 .iso image to your Pendrive. Make sure you don't cause any errors.

Now set the boot priority to your pendrive from bios and you can proceed with the installation as normal.
