What is the model number of your Dell computer?

Thank you for details on the question and your efforts to resolve.

I also know that the inconvenience that you are experiencing due to problem starting Windows. I will definitely help you.

This problem may occur because of damaged or missing Windows startup files. This can also occur due to damaged MBR (Master Boot Record).

I suggest you use the bootrec.exe tool and check if that helps.

    Hello

    I give my 15 years old nephew an old laptop so I am trying to run a system recovery and restore it to its original state factory.

    Windows could not start. A recent hardware or software change might be the cause. To solve the problem:

    1. Insert your windows installation disc and restart your computer. (don't have)

    2. choose your language settings, and then click "next".

    3. click on "Repair your computer."

    If you do not have this disc contact the Adminitrator's manufacturer or a computer in your system.

    Thank you!

    try to perform the recovery by using the partition.  boot f11 and recovery manager must take over. If not, or if the process does not finish successfully, perform a large hard drive. If the test successfully you will need to order a copy of your HP recovery disk.

    as an alternative, you can create a new admin account and simply delete your existing account after.

    Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

It cannot be used to install or reinstall Windows Vista, and is just a Windows PE interface to recovering your PC. Technically, we could re-create this installation with downloadable media media freely from Microsoft (namely the Microsoft WAIK, several gigabyte download); but it is pretty darn decent of Microsoft to present Windows users who might not be able to create such a thing on their own.

    ISO Burner: http://www.snapfiles.com/get/active-isoburner.html

    It's a very good Vista startup repair disk.

    You can do a system restart tool, system, etc it restore.

    It is NOT a disc of resettlement.

    And the 32-bit is what normally comes on a computer, unless 64-bit.

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    How to get Vista recovery Media or the Vista recovery Partition on your computer back to factory settings.

    There is no Vista free download legal available.

    Contact your computer manufacturer and ask them to send a recovery disk/s Vista set.

    Normally, they do this for a cost of $ small.

    In addition, ask them if you have a recovery Partition on your computer/laptop to restore it to factory settings.

    See if a manual provided with the computer or go to the manufacturer's website, email or you can call for information on how to make a recovery.

    Normally, you have to press F10 or F11 at startup to start the recovery process...

    Another way I've seen on some models is press F8 and go to a list of startup options, and launch a recovery of standards of plant with it, by selecting the repair option.

    Ask them if you can also make recovery disk/s for the recovery Partition in case of a system Crash or hard drive failure.

    They will tell you how to do this.

    Every computer manufacturer has their own way of making recovery disk/s.

    Or borrow a good Microsoft Vista DVD (not Dell, HP, etc).
    A good Vista DVD contains all versions of Vista.
    The product key determines which version of Vista is installed.

    There are 2 disks of Vista: one for 32-bit operating system, and one for 64-bit operating system.

    If install a cleaning is required with a good DVD of Vista (not HP, Dell recovery disks):

    Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

    At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu

  • My computer guard direct me to the Windows Startup Repair loop. Is this a virus? If this is not the case, what should I do?

    OK, here's a little history:
    When was surfing the Internet (using Mozilla Firefox), he froze and said that he "did not." Then I left the computer alone for a good 15 minutes, but to realize that nothing happened. From there, I decided to disconnect the computer to see if I can re - open Firefox. But when I tried to connect it back, the computer take me on the desk. It was stuck at the screen that says 'Welcome' (the form that appears after clicking on your user name) in the end, I turned off the computer by holding the power button, because there was nothing I could do. When I turned on the computer a few minutes later, it was time that I met a huge problem.

    The problem:
    When I turned it back on, a black screen appears that gives you the ability to boot your system with a repair on your computer, or start normally. I chose "start normally. After that, it took me a blue screen with a window that says "Startup Repair". He began to scan the computer saying «attempted repairs...» "When I saw this, I turned immediately shut down the computer, thinking it was some sort of virus that pretends to fix the computer. Nevertheless, I decided to turn it on for the second time. Of course, it's the same thing. But this time, I allow the scanning process to complete. When it was over, he said that the system could not be repaired and advised me to contact Microsoft, with my "contact information." I took this as a red flag, and click Cancel. I suspected it was an attempt to identity theft. (Though, I could be wrong, of course.)

    Honestly, I don't know if if there is indeed something wrong with the computer or if it's a virus.

    I tried to find out by going online and looking for solutions. From there, I tried a method where you press F8 several times until the Advanced Boot Options go up and selected "Last known Configuration" that did not work. I also heard on the "chkdsk" method, but I don't know how to do and there is no guarantee this will work.

    After that, I did more research and realized there were several ways to solve this problem. But when I went through the tutorials, the steps have been very confusing to me. I felt like most of these tutorials aimed computer technicians or people who knew in fixing computers. The steps were so confused until I found myself referring more questions than real answers!

    So now I'm reaching out to help, and I really need! It would be greatly appreciated! I really don't want to format all my data.

    Please keep in mind that I am a lover of computers operating. The two programs I normally use are Mozilla Firefox and Microsoft Word. So please don't be assuming that I know my way in and out of a computer. I'm no where near, in every sense of the term, an 'Expert '. If you can, I would like a simple, easy to follow, simple tutorial, step by step, which is not turned to professional users. Still, I am not very competent in operating computers.

    I can't get Windows Vista (which must be up-to-date with patches) starts correctly. He's trying to do the Startup Repair, but it is impossible to recover automatically.

    Last night I let the laptop (Dell Inspiron 1525) update iTunes 10.1. Once he had finished, I chose not to restart immediately, closed from programs running and stop.

    This morning, the computer complained to be stop incorrectly, traveled the Startup Repair (over an hour) and was caught in a cycle with no end to the Startup Repair failed.

    I tried looking for a file C:\Windows\winsxs\pending.xml (advice), but there is no such file. I removed an entry in registry PendingXmlIdentifier in HKLM\Components and a mention AdvancedInstallersNeedResolving even place.

    In addition, I can't without failure or last known good configuration mode. System Restore tells me it was successful, but it makes no difference. The last two changes concern Apple USB-driver and another driver of Apple to restore points.

    All attempts to no effect.

    I don't have Vista DVD/CD at hand.

    Any help or advice would be greatly appreciated.

    It is likely that the problem with the hard drive has corrupted your Windows installation.  I suggest a fresh new install of Windows.

    1 - backup of your data
    2 - start from the installation DVD (this looks like a Dell DVD - so you would have to press F12 at the Dell splash screen to enter the Boot Options menu)
    3 follow the prompts to install Windows

    I suggest you to download the driver of network cable from the Dell website to a flash drive before that.  In this way, you can install the wired driver and connect to the internet in order to get the rest of the drivers available for your system.

    To do this, go to http://support.dell.com/support/downloads/index.aspx?c=us&l=en&s=dhs and enter your Service tag.
    Scroll to the network section and download the wired network driver - if there is more than one, collect them all!  Once Windows is installed we can understand that one to use.

    Then, when Windows is installed and you are connected to the internet...
    1 - open up Device Manager and see what devices must be updated
    2 - visit the above Web site and download/install the drivers for these devices.

    For any question, right after back and someone will be able to help out you.

    Good luck!
