    Yes you can, if you plug the external hdd in and run your windows dvd it should let you choose to install it on the external. Alternatively you could try using unetbootin.sourceforge.net/.

    Its possible but not really recommended - especially if its a USB harddrive - the OS does a lot of random (and small file) accesses so would run painfully slowly over USB... (So okay for 'emergency' use but not a long term solution). Why do you want to install it on the external drive?

    I see, it should be possible to boot and get it to work but don't expect to be able to make a fair judgement of performance though as it will run a lot slower than intended...

    will also depend on your bios supporting boot from usb and legacy access, check their first before wasting a lot of time

    yeh will do m8 cheers

    Windows 7 cannot be installed directly onto an external USB hard drive - it will install using an eSATA connected hard drive though. If you are using a USB hard drive, then in order to achieve your aim you will need to remove the drive from the enclosure and connect it directly to the motherboard. Once installed, you can refit the drive back into its enclosure and set the BIOS to boot from a USB device.

    Another alternative to look into is running a virtual machine - this is where you run an operating system within another, if you have a Core 2 Duo system or similar performance isn't bad although graphics accleration is poor. Can be very handy for experimenting with operating systems as you don't lose any of your main operating system.

    You can download Microsoft's Virtual PC 2007 from here:

    microsoft.com/dow…=en

    Install Virtual PC on your computer, then install Windows 7 within the Virtual PC.

    Here is a video of how to install Windows 7 on Virtual PC..

    Here is a picture of someone running Windows 7 in a virtual PC under Vista

    I preferr Virtual Box to virtual PC, mainly because it supports USB better.

    As for installing windows on a usb drive, I'm almost sure that you can't boot up to a windows XP installation on a USB drive (unless it a BartPE install), I don't know about windows 7 but am prety sure that the installation would change the MBR on the fixed hard drive in order to boot to an external drive and that is not what the OP wants.

    I hope you've already got your download of Windows 7 then, as its not longer available to download:

    Info taken directly from Windows & page:

    Windows 7 Beta
    Sorry, Windows 7 Beta downloads are no longer available. You can still register for a product key or look up the key you've already gotten. To look up your product key, just pick your version and language below, and click Go. From there, sign in with your Windows Live ID, and your product key will appear on the next page.
