Install Windows 7 from USB Drive

Filed under: by: VASANT TIWARI

Hi everyone,

As I had mentioned in my last blog, I am here with the complete procedure to create a bootable USB Drive for Windows 7 Installation. The advantage of installing it from USB is that it is very fast. Believe it or not, but it took me only 15 mins to get my Win 7 OS ready.

So before going further, please make sure you have Windows 7 ISO file.

This procedure is for Vista Users:

For those who are using Vista, its pretty simply because of the utility called DISKPART that is already there in Vista. Here is the whole process:

1. Using Daemon Tools, mount the Win 7 iso on a virtual drive. And also insert a USB (at least 4 GB) in one of your USB Ports.
2. Click on Start --> RUN. Type cmd on the window that appears. You will see a command prompt window that comes up.



3.Type DISKPART in that window. You`ll find another Diskpart Utility popping up.



4. Type following commands:

List disk

This will show all the storage disk attached to your computer. You should note the number of the USB drive. This can be found out by checking size of the disks shown.



Now type:
Select disk 1 (if one is the number if your USB drive)
clean
create partition primary
select partition 1
active
format fs=fat32 quick
assign
exit

Thats it. Your USB is now ready to be used as bootable drive. The only thing remaining is to copy all the files from the Windows 7 iso to this USB. Simply copy all files from the virtual drive to the USB.

Good work vasant.
Something to add to that. If you are not able to access windows (like me) and want to make your USB windows 7 bootable then you can follow these instructions for UBUNTU :

1. Install Gparted and ntfsprogs.
sudo apt-get install gparted ntfsprogs
2. Insert your USB (atleast 4 GB), open Gparted, choose sdb partition.
3. Right click and then choose UNMOUNT.
4. Right click and choose format to NTFS and then apply.
5. Re-insert your USB.
6. Mount your win7.iso
e.g sudo mount -o loop win.iso /media/cdrom
7. copy all the file and folders to your USB.

Your USB is now windows 7 bootable. Njoy :)

This procedure can be followed to make any OS bootable :-D

What i did was.
1.Quick format the usb
2.mount the iso file using alcohol120
3.open the cmd and change the directory to H:(H is the virtual drive where iso file is mounted)
4.cd boot
5.bootsect.exe /nt60 I:(I is the drive name of the inserted usb)
6.copy all the files from dvd to usb.
No need of doing giving all those duskpart commands.I gave only one unknown command bootsect.exe /nt60 I:
