Windows 7 - dual boot with external hard drive

Hi, i just bought a laptop with Windows 7 home premium 64 bit and I want to dual boot it with Windows 7 32 bit..Can you teach me how to dual boot with external hard drive?

Second, any external hard drives will do?

You cannot install Windows to a USB device.

To Dual Boot follow the same steps given here, making sure to boot the installer as it will not run from another bit-version: Dual Boot Installation with Windows 7 and Vista

can't I dual boot with another Windows 7?

Yes, if you have two licenses.

The steps are in the tutorial I linked above.

But you cannot install Windows 7 to a USB drive. Use an internal HD or eSata connection.

okay thanks a lot gregrocker

Hi, so I finally dual booted my laptop with Windows 7 32 bit...

and the problem here is that I can't connect to the internet..

I tried troubleshooting and said that I have no network adapter..

I can't also turn on on my wifi and still can't connect with wire..

Can you help me with this pls?

Install your Ethernet and Wireless Network Adapters in Device Manager.

You can find them on the Support Downloads webpage for your model computer or Device.

Once connected via System Tray network icon, update your drivers via Optional Windows Updates.

it works at last! thank you so much sir

You're welcome. Let us know how it goes.

I have to ask, and I'll preface this by saying that I despise dual-boot setups, but what would be the purpose of dual-booting the same OS? You are wasting a second license. If you need app compatibility, run XP Mode, or some other virtualization app. Simplify!
