How to create a bootable USB


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. In the below image my USB drive disk no is Disk 1.

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)






(Format process may take few seconds)


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.

(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.

Instale o Windows 7 por um PenDrive

Microsoft, disponibilizou uma ferramenta chamada Microsoft Windows 7 USB/DVD Download Tool, que possibilita a criação de um pendrive inicializável e com todos os arquivos necessários para que a instalação do Windows 7 seja feita.



A interface do Microsoft Windows 7 USB/DVD Download Tool é bem simples, contando com poucas telas e opções, o que lembra muito os assistentes de instalação do Windows. Ao todos são quatro passos para a criação de um disco inicializável, cada um deles descrito em uma tela do programa. Para avançar até a próxima etapa, basta escolher as opções desejadas e clicar em “Next”.

Rodando Windows de um USB flash drive

Ótima documentação que mostra como configurar um pen drive USB para rodar Windows 7 (Live USB)


I’ve titled this post as “Running Windows from a USB flash drive” because the same principles should be equally applicable to all Windows 7-based operating systems (and even Vista if the Windows 7 bootloader is used) but my specific scenario was based on Hyper-V Server 2008 R2.
I got this working a few hours after Windows 7, Server 2008 and Hyper-V Server 2008 R2 were released to manufacturing but I was still using release candidate code – fingers crossed it still works with the final release!
Boot from VHD is a fantastic new technology in Windows 7/Server 2008 R2 and derivative operating systems and I’ve often wondered if it’s possible to use it to run Hyper-V from a USB flash drive (just like the “embedded” version of VMware ESXi offered by some OEMs). Well, as it happens it is – and this post describes the steps I had to take to make it work.
First of all, I needed to create a virtual hard disk and install an operating system onto it. As Keith Combs noted, there are various ways to do this but only one is supported; however there is also a handy video on TechNet which takes you through the steps of creating a VHD and booting from it.
Using the TechNet video as a guide, I issued the following commands from the command prompt to create my virtual hard disk and apply an image from the Hyper-V Server 2008 R2 release candidate DVD:
create vdisk file=driveletter:\virtualharddisk.vhd maximum=15000 type=expandable
select vdisk file=driveletter:\virtualharddisk.vhd
attach vdisk
list disk
(make a note of the disk number.)
select disk disknumber
create partition primary
select partition 1
format fs=ntfs quick
(note the drive letter for the newly mounted VHD.)
imagex /info dvddrive:\sources\install.wim
(identify the correct entry.)
imagex /apply dvddrive:\sources\install.wim /check imageindex vhddrive:\
select vdisk file=driveletter:\virtualharddisk.vhd
detach vdisk
At this point, Hyper-V Server had been imaged into my new VHD, which could then be copied to the USB flash drive.
Next, to load the VHD from the Boot Manager, I edited the boot configuration data (which is what would be required in a standard boot from VHD scenario); however, as I found later, a different set of actions is needed for booting from the USB flash drive.
bcdedit /copy {current} /d "Hyper-V Server 2008 R2"
(make a note of the GUID for the newly created entry.)
bcdedit /set {guid} device vhd=[usbdrive:]\virtualharddisk.vhd
bcdedit /set {guid} osdevice vhd=[usbdrive:]\virtualharddisk.vhd
bcdedit /set {guid} detecthal on
bcdedit /set {guid} description “Hyper-V Server 2008 R2″
It’s worth understanding that the use of drive letters (which are transient in nature) does not cause a problem as the BCD Editor (bcdedit.exe) extracts the data about the partition and saves it in the BCD store (i.e. it does not actually save the drive letter).
After rebooting, Hyper-V Server loaded from my USB flash drive and ran through the out of box experience. At this stage I had Hyper-V Server running off the flash drive but only if my original Windows installation (with the boot manager) was available and, as soon as I removed the hard disk (I wanted to be sure that I was booting off the flash drive with no other dependencies), then the whole thing collapsed in a heap. Thanks to Garry Martin, I checked my BIOS configuration and made sure that USB device boots were enabled (they were not) but I then spent about a day playing around with various BCD configurations (as well as various attempts to fix my BCD with bootrec.exe) until I stumbled on a post from Vineet Sarda (not for the first time, based on the comments that include one from yours truly a few weeks back!) that discusses booting from VHD without a native operating system.
Following Vineet’s example, I booted my system into Windows 7 (I could have used the Windows Recovery Environment), reformatted the USB flash drive before copying my VHD image back onto it, and issued the following commands:
select vdisk file=usbdrive:\virtualharddisk.vhd
attach vdisk
list volume
(note the drive letter for the newly mounted VHD.)
bcdboot vhddrive:\Windows /s usbdrive: /v
(i.e. copying the BCD from the operating system image contained within the VHD, to the physical USB drive. Note that, when running on a live system it is important to specify the target drive for the BCD in order to avoid overwriting the live configuration.)
I then shut down the system, removed the hard disk and booted from the USB flash drive, after which the Windows Boot Manager loaded an operating system from within the VHD.
Looking at my BCD configuration (shown here for reference), I can see the source of my many hours of confusion – the Boot Manager resides on the physical media (my USB key – which was allocated drive D: in this case) and loads an operating system from the virtual disk that is given another drive letter (in this case C:):
Windows Boot Manager
identifier              {bootmgr}
device                  partition=D:
description             Windows Boot Manager
locale                  en-us
inherit                 {globalsettings}
default                 {current}
resumeobject            {27f66313-771a-11de-90bb-00037ab36ab6}
displayorder            {current}
toolsdisplayorder       {memdiag}
timeout                 30
Windows Boot Loader
identifier              {current}
device                  partition=C:
path                    \windows\system32\winload.exe
description             Hyper-V Server 2008 R2
locale                  en-us
inherit                 {bootloadersettings}
osdevice                partition=C:
systemroot              \windows
resumeobject            {27f66313-771a-11de-90bb-00037ab36ab6}
nx                      OptOut
detecthal               Yes
It took a while to boot (my flash drive was a freebie is not the fastest in the world) but, once loaded into memory, Hyper-V Server seemed to run without any noticeable delay. I figure that, as long as the workload is stored on another disk this should not present any problems and, given suitably fast flash memory, it ought to be possible to improve boot times as well. Running a full Windows operating System (e.g. Windows 7) in this manner is an entirely different matter – very few USB flash drives will be able to stand the constant writes and further testing would be required.
Now that I have Hyper-V Server running from an inexpensive USB flash drive with no reliance on my PC’s internal hard disk, all I need to do is inject the correct network drivers and I will have a virtualisation solution for colleagues who want to run a full hypervisor on their corporate notebooks, without deviating from the company’s standard client build.

Note that the boot from VHD functionality in Windows 7/Windows Server 2008 R2 does not support the use of BitLocker or hibernation

Converta seu HD em VHD

Uma das novas funcionalidades do Windows 7 é a de permitir que arquivos VHD (Virtual hard Disk) sejam usados como discos físicos. Agora uma novidade legal é que podemos transformar nosso HD em VHD. Entre várias vantagens, podemos falar na possibilidade do backup de todos os dados do nosso micro, incluindo Sistema Operacional.

Para isso iremos precisar de uma ferramenta bem simples chamada DISK2VHD que pode ser baixada do próprio site do Technet Brasil através do link

A ferramenta é simples de utilizar e não gasta mais do que 20 minutos para converter dos os seus dados para um arquivo VHD, após a conversão poderemos fazer uma cópia do arquivo a mantê-lo guardado, caso seu micro seja infectado com vírus ou até ocorra de você perder seu micro inteiro, os dados estarão salvos.

Entenda a interface do Windows Phone 7



A interface do recém anunciado sistema operacional para telefones da Microsoft é uma revolução na maneira de navegar em um dispositivo. Ela funciona como se você estivesse navegando em uma grande área horizontal em cada sessão do sistema.


Assim como aconteceu com o Windows 7 (sistema operacional de desktop da Microsoft), o Windows Phone 7 recebem ótimas críticas de várias páginas especializadas ao redor do mundo.


Abaixo um trecho de uma delas:

Windows Phone 7 feels like an iPhone from the future. The UI has the simplicity and elegance of Apple’s industrial design, while the iPhone’s UI still feels like a colorized Palm Pilot.


Telas demonstram melhor como funciona a interface do futuro sistema operacional para celulares da Microsoft.
