Installing Windows 7 from a pen drive

[DeSmOnD dAvId]

Here's a step by step guide to create a Windows 7 bootable USB drive.

Things needed : A pen drive (atleast 4 gigs), Windows 7 disc

- Attach the pendrive

- Run the command prompt (as Administrator)

- Type "diskpart"

This starts the diskpart utility and you will get the DISKPART> prompt

- Type "list disk"

This displays the list of all disks connected to your system

- Type "select disk <enter_disk_no_here>"

Replace <enter_disk_no_here> by the disk no. of your pendrive as shown in the list. Make sure it is the right disk by verifying its size and read its appropriate number as you might risk nuking your drives. Note that all data on the drive is lost so backup any important data on the drive before proceeding.

- Type "clean"

This will clean any partition off the drive. This means the drive is now kaput and we can proceed to make a new partition.

- Type "create partition primary"

Creates a new primary partition on the pen drive

-Type "active"

Marks the newly created partition as active

- Type "format fs=ntfs quick"

Performs a quick format of the partition into the NTFS file system.

- Type "assign"

Assigns a new drive-letter to the drive. Note this drive-letter. Lets say it is J:

- Type "exit"

Quit the diskpart utility and you are back to the command prompt. Make sure you run the command prompt as an Administrator if you have not already.

- Pop in your Windows 7 disc. Lets say its drive-letter is D:

- Type "d:"

- Type "cd boot"

- Type "bootsect /nt60 j:"

Installs a new bootsector in the pendrive. Note that the drive-letter j: is as assigned in the previous steps.

- Copy the entire contents of the Windows 7 disc to the root of the pen drive. i.e. from D:\ to J:\

Thats it, you can now use your pen drive to boot your system and install windows.

Is there a source for this tutorial ? Please mention it.

Ah.. There are far more simpler ways than this:

1) UNetbootin - Homepage and Downloads

2) Windows 7 USB/DVD Download Tool

You can use any of the above tools and directly "burn" the Windows 7 ISO to your pendrive. Then you can boot using the pendrive.

This is how I do it. I don't rely in third party tools.

@shantanu, this is in my own words.

reduces considerably with respect to what? Installation from DVD or installation using other mentioned softwares?

Here's my source, which I referred while making my own bootable Windows 7 Pen Drive:
Install Windows 7 Or Windows 8 From USB Drive/Pen Drive

And it worked flawlessly. After I made the drive bootable, I just had to copy all installation files to the drive.
I can even use it like regular pen drive, by deleting the contents. But as soon as I copy the installation files again, it can be again used to install Win 7. Meaning, as long as you dont format the drive, it can anytime be used to create the bootable Win 7. Love it

reduces in terms of time using usb......it takes less than half the time it would take while installing using a DVD...after all its a usb right?

[shantanu]

@desmond David : Please mention the source for your work. Else I will have to close your thread.

[DeSmOnD dAvId]

Alright I read it somewhere online...but that was a long time back. Don't remember the source now.

I use this

WinToFlash - Install Windows From USB - Download Page

[prabhu.wali]

or u can jus ntfs format the usb and copy the image onto it and jus boot,it worked for me

[DeSmOnD dAvId]

That would probably be because "bootsect" might already be done on it.

Last time I used ultraISO on 2006 - made a win 98 SE and Xp SP2 - 2 in 1 bootable CD

The nain purpose of reformatting USB drive to make its drive as a active one so bios can use it as a harddrive for booting. After making a active drive mount you DVD or insert your win7 or vista DVD into your DVD drive copy all the content inside using mouse or control+a and then just paste it directly into the root of usb drive(no need for cmd for copying installation data from source), done.-)

Ok, done. Hope it helps you.
BTW how did you know, its Orange?

The other alternative to read the coloured text is, just copy the text, paste it in 'Notepad'. Now you can read the text as the whole text will be in black colour.

[Vyom]

^^ LOL man! I am not color blind! But that orange was not at all eye pleasing!
So thanks for changing that!
