    I want to install it on the external hard drive.

    Is it possible to install windows 7 on a USB external hard disk like the one above?

    If yes then how?

    If i have it connected all the time then i am sure i can boot from it.

    I want to ask if anyone has done this before and if its working fine with him.

    Because in case my internal hard disk has a hardware failure (Which happened before and i lost all the data from it then i had to replace the hard disk) i can still boot up from the external hard disk.

    Have you heard of "Imaging" a system to a data file in an external HDD ??

    I have an external with a bootable backup system in it ... But I have to remove the HD from the External Enclosure ..
    and install it in my Computer to run it.
    Don't think you can do this with the external HD you have.

    This will take an External Enclosure .. and a HDD that can be installed in you Laptop ...
    (I'm assuming we're talking about your Laptop)

    USB will be awful slow to try to boot from it.
    There might be a way to get a eSATA enclosure and a card for your Laptop ..
    Then you could boot from the external.
    Does you external have an eSATA connection in addition to the USB

    No only USB.

    But i have another option:

    If i partition my internal hard drive will I be able to install windows 7 on the other partition?

    If so then please tell me it will be a relief.

    OP - I don't think Windows will install to any USB device, unless W7 has changed... :confused:

    You should be able to do this ... But again I ask :D ... WHY ??
    If the HD crashes .. You'll loose both of the operating systems.
    I've also read many horror stories about dual systems on one HDD ... Where one of them is W7
    Break one .. Or try to fix one ... And the whole HDD is broken.

    Your problem is that you have a Laptop and can only install one HDD.
    The first things you should do is ...
    1) Make sure you have your Windows recovery DVDs .. or the W7 DVDs.
    2) Make a W7 repair CD
    3) Get Acronis or Macruim Imaging programs .. and Backup your operating system to the XHD.
    4) Make sure you have all your personal Data Backed up in the XHD.

    Then ... You should Think about being able to Install a new HDD in the Laptop ... And ..
    5) Get an external HD enclosure .. And a new HDD for the Laptop.
    6) Install a backup OS on the New HDD.

    I have Emergency (replacement) HDDs for all my computers .. Including my Laptop.
    I've had to use them several times.

    There's only two types of computers made nowadays ..
    Those that have Crashed or got corrupted ... And those that will ..
    Which do you have ???

    I've also had a XHD fail .. Thankfully, I have more that one.

    I'm pretty sure you can't install Windows 7 onto a USB drive, nor boot a Windows 7 installation from a USB drive. It has never been possible before due to restrictions place by Microsoft and the way Windows handles drivers. And even if you could it would be much slower then running from an internal PATA or SATA drive.

    Having a secondary partition with Windows installed will do nothing for you if the hard drive has failed. And if done after the fact can lessen the chance of data recovery.

    The best solution is to have an image to restore onto a new drive if a failure occurs.

    To recover data off a failed hard drive you can use a bootable Live Linux CD or place the failed hard drive into an external USB enclosure and access the data off it that way.

    So you are saying that using dual boot with Windows 7 is risky?

    Its just not very effective. it wont help if the drive fails, if the partition or file system becomes corrupt, and it might not even be useful if the computer gets infected by a virus - some viruses will infect files on any partitions.

    Creating a backup image as has been suggested several times. Acronis TrueImage is great for such a task.
