Reinstall Windows 7 Home and reupgrade to Windows 7 Pro

I have a Dell laptop, Inspiron, provided with Windows 7 Home installed, but without the installation diskettes. I've also upgraded to Windows 7 Pro. I need a new hard drive. How can I reinstall Windows 7 Home and reupgrade to Windows 7 Pro, without going through the installation of operating system diskettes and without having to purchase another upgrade of Windows 7 Pro or the original operating system?

Thank you.

I would recommend that you create your recovery disk that will allow you to reinstall Windows 7 Home Premium:

Creation Your system with Dell DataSafe Local recovery discs...

If its damaged, then you will need to request a new set of Dell:

Request backup discs - welcome to Dell Technical Support

It allows to reinstall Windows 7 Home Premium, then reactivate again Express upgrade. Make sure you have your Windows 7 Professional key on-site. If you do not, make sure that you pick up before the deletion or the format of the player:

Click Start, type Anytime Upgrade, click on the option enter a key, enter the key of Windows 7 Professional on demand, click Next, wait while checking the key, accept the license agreement, click on upgrade, wait while the software upgrades, (it may take 10 minutes or more depending on the if updates are required) your computer restarts automatically, after the reboot, Windows 7 will notify you updating the computer, the computer will restart once more automatically and will be completed the upgrade, a window will appear notifying the upgrade was successful and your computer is ready to use, click Close, you should be upgraded to Windows 7 Professional your files, programs and settings retained.

  • I had to reinstall Windows Xp Pro, the product key will not work.

    I have not changed any hardware or anything like that. I downloaded the updates of msupdates and my computer went the fritz would not do anything. I reinstalled windows xp pro from the restore disc that came with my computer. The product key is not accepted by windows to activate it. I need to know what to do. It's a Dell optiplex 2.8 gig Board and proc 2 gig of ram. Anyway when I bought.

    Hi, I am assuming that you are unable to activate your XP via internet, you can try the phone holder to turn on.

    You will be asked of the remote computer to give the support page for phone numbers.

    You will then receive a new set of numbers to activate your XP.

    If this does not work, you will be directed to a Microsoft employee. Explain your problem and if they are happy with your answer will give you an activation key.

  • missing Ntoskrnl.exe and other errors when who reinstall windows 7 pro 64-bit

    I had windows installed on a HARD drive and received an SSD and I decided on the SSD HARD drive image, so I wouldn't have to reinstall. As I suspected it might that cause some problems and I decided to simply wipe the SSD drive and attempt to reinstall. I wiped the SSD and started my windows 7 Professional 64-bit SP1 DVD. It will pass through the first process (Windows loading files) with the screen of levels of grey and the downstairs, but subsequently loading bar, I get an error telling me that the ntoskrnl.exe is missing or damaged, and I have no option other than to try again to load the disc, or stop. I have another disc of Windows 7 Professional 64 bit I tried to use, and it gave me the same message. There are a few other errors I received, I do not at the moment, but as soon as I get some time and if I get them again once I will update the thread with this info.

    I also ran memtestx86 and there were errors with a specific location, but I just removed the RAM of this niche and I guess it should be OK after that. Am I wrong?

    I am the computer OEM. If I need to provide more information please let me know and I can accommodate.

    Thank you.

    The problem was with RAM. One of my 4GB DIMMS was bad. I removed and changed my poles autour needed and I could boot disk Windows 7 Pro and install correctly.

  • Reinstalling windows 7 pro/restorePLEASEHELP

    I'll buy a new Win 7 PC before they are gone.  I have Win 7 Pro on the old PC.  Can I uninstall and reinstall on the new PC?  How to uninstall it without a full factory restore?  My computer tech said a full factory restore could damage the system, given that I added 4 g of RAM, a 1 TB internal hard drive and a power of 500W.  I have still my discs and they seem to have no scratches, I checked.  My PC is 3 years old and I intend to sell it.

    If the old PC came preloaded with Windows 7 Professional, you can not transfer to the new computer. This is because its what you call an OEM license.

    The OEM of Windows 7 versions are identical to the versions commercial full license with the following exception:

    -OEM versions don't offer any free direct support from Microsoft technical support Microsoft

    -OEM Licenses are tied to the computer first you install and activate it on

    -OEM versions allow all hardware upgrades except for an upgrade to a different model motherboard

    -OEM versions does not move directly from an older Windows operating system

    What is OEM software? :

    http://support.Microsoft.com/GP/oemsupport_1/en-GB

    Licensing FAQ:

    http://www.Microsoft.com/OEM/en/licensing/sblicensing/pages/licensing_faq.aspx

    If this is a separate store bought license, then all you need to do is to withdraw the product licence in form of the machine or reinstall the original license that came with this machine.

    I leave the Windows 7 Professional license, since the new computer comes preloaded with Windows 7 already.

    Your computer technician has no knowledge, do a factory restore will not damage the computer, its a feature of most modern computers.

    New computers coming often pre-installed with Windows 7 have what is called a recovery partition. This is used to reinstall an operating system in the case of a system failure. To access it, you need to start when you start your computer by pressing a function key. This can be either F1, F2, F9, F10, F11, F12 key DEL or tab. See the manual that came with your PC for instructions on how to reinstall Windows.

    This is how the recovery partition is accessible to most popular brands...

    For Dell, press CTRL + F11 directly after switching on the device

    For HP, press F11 directly after switching on the device

    For LG, press F11 directly after switching on the device

    For Toshiba, press and hold "0" BEFORE and during the power upward

    For Acer, press and hold ALT + F10, as soon as you see the logo

    For Asus, press F9, as soon as you see the Asus logo.

    For Samsung, press F4 to the power upward...

    For Fujitsu, press the F8 key directly after the power

    Advent, restart your computer. Then, press F10 repeatedly until the message "Starting system recovery"

    Sony VAIO, reboot and press "F8" or "F10" repeatedly until the screen "Advanced Boot Options".

    ------------------------

    Once you remove it, you can use the product key to upgrade the new computer.

    If the license for Windows 7 Professional, you have access to is a retail version update or complete, you can use the product key and the Express upgrade to Windows 7 Edition Home Premium to Windows 7 Professional. First of all, check that the edition of Windows 7, you are upgrading is already enabled (if it isn't, you will encounter complications and that you might start all by performing a clean installation). Click Start, type Anytime Upgrade, click on the option enter a key, enter the key of Windows 7 Professional on demand, click Next, wait while checking the key, accept the license agreement, click on upgrade, wait while the software upgrades, (it may take 10 minutes or more depending on the if updates are required) your computer restarts automatically, after the reboot, Windows 7 will notify you updating the computer, the computer will restart once more automatically and will be completed the upgrade, a window will appear notifying the upgrade was successful and your computer is ready to use, click Close, you should be upgraded to Windows 7 Professional your files, programs and settings retained.

  • Reinstall windows xo pro sp2/sp3?

    Have a laptop with Windows XP Pro SP2 and it is 32-bit. I want to reinstall the OS, but I do not have the CD. How to do this? Where can I get the operating system? Can I download it from any source? Any link?

    Now the latest service pack for XP's SP3. So I can download SP3 from the windows website and install it in my pc. Is it free? At the bottom of my pc

    There is a sticker that shows the product key. But I think it's the product key of Windows XP SP2. I want to know that can I download XP SP3 and use this product key to reinstall the OS? Am I wrong?

    Please explain in detail what to do after I downloaded the OS? I want to download on another computer. How to make a CD so that I can install windows via a CD?

    Probably, your laptop has a depression recovery accessible by the F key or modified mechanism F (for example Ctrl) key at boot time. To learn more about this we need the details of your laptop (brand and model). You can find this documented somewhere in the start menu or in a booklet that came with the laptop.

    In addition, there are probably a facility to create your own recovery CD/DVDs. Again, look in the start menu and in any document paper. If this facility exists, you should do so as soon as possible because it's your only method of recovery in case of hard drive failure.

    Otherwise recovery integrated and/or the creation of recovery media, you will need to contact the manufacturer for recovery media.

    You can download a standalone SP3 Installer of...

    http://www.Microsoft.com/download/en/details.aspx?displaylang=en&ID=24

    .. .This is only a service pack installation, not a full installer of XP operating system. You can ignore the text which says that it is for network installations and also ignore the text informing Windows/Microsoft Update If a single update of a PC. You will not request a product key.

    Indeed you will need this installer of SP3 update of the OS until Windows Update will be operational. Install it before even to try Windows Update.

    Recovery of the manufacturer would not normally require the entry of the product key of your sticker. But if this is the case, the key on the sticker is good for recovery and updates including SP3.

    After recovery, you must uninstall any AV solution came pre-installed, do the SP3 upgrade without being connected to the internet and then install Microsoft Security Essentials for which a standalone installer can be downloaded here, for example...

    http://www.Microsoft.com/en-US/Download/details.aspx?ID=5201

    .. .or here...

    http://Windows.Microsoft.com/en-us/Windows/Security-Essentials-download

    Then you can connect to the internet and download MSE (or alternative AV) updates and Windows updates.

    A standalone IE8 installation program can be downloaded here...

  • Device drivers are on CD to reinstall Windows XP Pro?

    I recently got a computer that has erased hard drive and Windows XP Pro reinstalled OS. But the Device Manager indicates that these drivers are not installed: Multi Media Audio Controller, SM Bus controller, Ethernet, USB controller controller & video Controller.Are the drivers on the reinstallation CD (which I have) or they are on a separate CD?

    Many computers need drivers that are not on the Windows XP reinstallation CD.  For example, Dell computers usually come with a Drivers and Utilities CD.

    Using another computer, go to the web site of the manufacturer of the computer and look for the downloadable drivers on your computer.

  • Upgrade of large computers without having to reinstall windows 7 PRO?

    Hello, all the

    I'll be upgrading the motherboard, sound, video, memory, and processor on my current computer (I built it myself).  I will keep the same disk configuration.

    I have here some so that I can do this without having to reinstall Windows again?  My copy of Windows 7 Pro is a copy retail NOT oem.

    I read a bunch of different items on the net, but responses varied considerably.  My apps are all installed on the boot drive and all data, backups and documents are in a separate table in mirror. I'm trying NOT to do a clean install, because I have about 27 apps, some of which are quite massive and would take me more than a full day to reinstall.

    Thanks in advance,

    Jeffrey

    PS, just in case I need to specify the components, they are:

    MOBO - ASUS AM3 MSI AM3 + both with RAID support (hardware)

    Processor - AMD Phenom 8 core Core AMD FX Vichera 6

    Sound - Sound Blaster Audigy (legacy) to Sound Blaster Audigy PCI Express

    Video card will not change

    No, I think you need to perform the migration of a motherboard to another as simple as possible. No devices, cards Add on or what that what else option means that Windows is more likely to address changes in pilots limited successfully.

    Then restore optional lights preferably one at a time.

    Each RAID (manufacturer) solution can use proprietary systems, but within the same manufacturer, they tend to be fairly stable. I left a RAID Intel ICH6 for ICH9 without any problem. Also keep in mind that a mirrored pair does NOT use any form of ownership anyway. Set them on a platform no RAID and the data must be fully accessible.
