  If you did a backup image of your computer before you upgraded (really a clean install when moving from Windows XP to Windows 7) - then you are fine - you can restore that.  Backups are King.

  If you do not have an image: you can still perform the clean installation of Windows XP - but all * not * maybe lost again...  You are likely to discover (or discovered) when you upgraded to Windows 7 from Windows XP - you had to reinstall all of your software - same thing on the other side, if you do it this way...

  Hello

  I see a long list of drivers that need to be updated: O
  But I m not surprised because all the drivers of Toshiba pilots and as far as I know these drivers are designed for only the WinXP. Request as a result of update.

  But as you may know Vista is not official on the market and that's why you won't find any Toshiba Vista drivers on the Web site.
  I think that Toshiba will offer drivers if Vista will be official on the market.

  We will have to wait

• EliteBook 8440p: elitebook 8440p upgrade of windows 10 mess with boot

  Hello!

  I bought a refurbished elitebook 8440p with pre-installed windows 7, 8 GB of RAM, 2.40 GHz processor.  I continued to refuse the upgrade of windows 10 when he constantly jumped upward and then one day I turned on the computer and it updated in any cases without permission.

  Since the upgrade, if I shut down my computer, or try to put in standby or Hibernate mode, when I go to wake up or put on, I always get a white screen. In general, I have to turn power several times on and off until any startup screen. Then half of the time, when I get a splash screen, my cursor is stuck at the top of the page, moving only left or right whenever I try to move it. So I have to turn and turn until a new screen is displayed.

  I studied how to remove 10 windows and reinstall windows 7. I passed the period of 10 days or 30 days. Media creation tool asks for the product key which I type in the sticker on the bottom of the laptop, but do not pass the verification process saying to contact the manufacturer for help.  Apparently there may be specific drivers or something you took when it improved and the media tool does not allow me to create anything for me to do a clean reinstall of windows 7.

  I tried to find an option after pressing esc at the f11 reset start screen. There was no option to do so. The best I could do was to 'reset' of the computer, but he took back to the original Windows that it is firstly set at level 10 to. All my files are deleted from the computer. I just want to return to Windows 7, but could not find an effective way to do it.

  Thanks for any help you can offer.

• What is the correct recovery process once upgraded to Windows 10? (No OneKey Recovery)

  I have a cell phone Z50-70 which is preinstalled with Windows 8.1. It is an OEM version, with the product key that is stored in the Bios. This is an installation of UEFI.

  The vehicle currently has OneKey recovery installed, which, if I understand well (I've not used actually still), allows you to recover from a hard disk recovery partition. This is not a "fresh" Windows 8.1, but an image provided by Lenovo that take back you to the State the laptop was bought originally (will have all software Lenovo and preinstalled drivers).

  According to the official upgrade guide Lenovo, before performing the upgrade of Windows 10, we should uninstall basically all software from Lenovo, including OneKey recovery and it won't work in Windows 10.

  Issues related to the:

  1. What is the correct process to recover the system from Windows 10 if something goes wrong? I think that Windows 10 integrates a feature "Reboot your computer" in the settings which I suppose is what we are supposed to use. It would take me to:

  a. a completely new install Windows 10?

  b. a created image during the upgrade from 8.1 to 10, containing all my files etc. when performing the upgrade?

  c. or he would use the recovery partition from Lenovo (which would have used OneKey Recovery if it was compatible) and take me back to 8.1 for Windows?

  (d) another thing?

  2. once I did the upgrade and Windows 10 has successfully activated, I think I could create a bootable with ISO of Windows 10, inside boot media and install a completely new install of Windows 10 and activate it. Theoretically, I could make as many fresh installs from the boot media I want, as long as initially, I did the upgrade (not a clean install), and the hardware of the laptop does not change. Is this correct?

  2A. If, therefore, during the first boot media clean installation process, I'd be sure compeletly remove the Lenovo recovery partition entirely and go from there, rely on 'Reset your PC' feature of Windows 10? Could I could use even just reinstall Windows boot again media 10 as a way to recover? If I understand correctly, it is not absurd to keep recovery partition it if it can not be used within Windows 10.

  I think I had a desktop PC ordinary with a retail version of Windows, then everything above would be fine. The complications added here are that 1. I have no product key Windows 8.1 (alll is managed by the BIOS) and 2. I have no recovery disk. I want to make sure that I understand everything completely before moving, and potentially do a clean installation using bootable media, so that I don't end up ruin something and end up with either a laptop I can not recover, a Windows installation that is not enabled.

  Thank you.

  Update for anyone of another reading:

  I just uninstall OneKey recovery on my installation of Windows 8.1 for the upgrade. While Windows is concerned, OneKey Recovery has been completely removed.

  The good news is that I then shut down the laptop, you press the novo button, selected "System Recovery" and I was always greeted with OneKey recovery program where I could choose to restore from original image, or a custom image. So I guess that once I have upgraded to Windows 10, I'll always have the option to restore to the factory Windows 8.1 if I ever need/want to.

  The confusion seems to be that OneKey recovery software is actually two separate software:

  1 OneKey Recovery #1 is installed in the hidden recovery partition which is responsible to perform a system restore from the image of your choice - either the image of plant or a custom image created by #2 OneKey recovery software. OneKey Recovery Software #1 is still accessible via the Novo button.

  2 OneKey Recovery #2 is installed on the Windows 8.1 installation, which is responsible for the creation of custom system images. You can also choose to restore the system from here, but AFAIK, it just restarts the computer and OneKey #1 software, which allows you to recover expenses. OneKey Recovery #2 is the software Lenovo told us to uninstall it before Windows 10. However, uninstalling OneKey Recovery #2 let software OneKey Recovery tact #1.

  As far as I know, this means that the uninstall OneKey Recovery #2 mean that we lose the ability to create custom system images, but we reserve the option to restore from a system image.

  Can anyone confirm that I understood, and that what I said above is indeed the case?

  I'm still a little uncertain about what Windows built tens in the willingness to ' PC ' do well - that it will use the Lenovo recovery partition or run a 10 Windows Installer Clean up.

• HP ProBook 655 G1: upgrade to Windows 8.1 to downgrade from Windows 7

  Hello

  I just bought a refurbished HP ProBook 655 G1 with Windows 7 Pro (64 bit) for my wife to use for the job.  I just found out that so that with my wife to support, they now require Windows Pro 8.1 (by the way, does not support Windows 10, so the free update for which I am eligible won't help).  Apparently, the machine came with Windows 8 pro license, even if it is currently running Windows 7.  I need to go back to Windows 8 and upgrade to Windows Pro 8.1.  Because the machine is not come with any type of installation or media recovery, how should I do this?

• HP Pavilion 15-p264na: upgrade of Windows 10 - recovery disk

  I just bought this laptop with win 8.1 on. I want to upgrade to windows 10 and produce a recovery disk using the installation of HP, which cannot be done at once. The question is what to do first. I'm afraid that if I do first the disc, then I assume will only recover Windows 8.1, which means another upgrade to win 10, which then can no longer be available as a free update. If I do the first update, should I still the ability to produce a recovery disk? and if he will he recover to win 10?

  Hello:

  You must make the recovery W8.1 media now before moving on to W10.

  It will only take up to W8.1, and no matter what you do, it will only retrieve W8.1 by using the HP tool to make the drive.

  Upgrading to W10 has no effect on the change of the W8.1 recovery partition.  Only, it installs W10 on the C:\ drive and makes no other changes.

  Here's how I see the second part of your concern (what concerns me too).

  Like you said after next July, W10 is not free, what happens if you need to restore W10 or you get a new hard drive and you have to install everything.

  First of all, after you upgrade to W10, in the tool settings > activation, you can check that W10 is enabled.

  I'd say you need to reinstall W8.1 and then upgrade to W10 and when you go to turn it on going because he already know that W10 has been installed on the PC before.  Microsoft maintains a database of activation which should allow the PC to have W10 still for free.

  You can make a W10 installation/repair ISO disk usb flash drive, or from the link below.

  http://www.Microsoft.com/en-us/software-download/Windows10

  Another thing I did was to create a system image of the installation of the W10 and recorded on a portable hard drive.

  I did use the tool to create system image (windows 7) in the W10 system control panel option.

  My plan would be to try first before anything else.  You can use the installation/repair W10 disc that you create to access the system image that you create, and I hope that will save a lot of time and effort.

  You can update the image of the system as many times as you want, and it will overwrite the existing image on the laptop hard drive.

  But until next July comes and goes, we can only speculate what will be the result of having to reinstall the W10.

• EliteBook 8760W: upgrade of Windows 10 works not

  I am trying to upgrade Windows 7 Pro for Windows Pro 10, with little success.

  Can you advise me on what my next steps should be?

  Hello;

  Let me welcome you on the HP forums!

  I've updated several PC Win7 Win10 - and they had all these problems in one way or another... so I wrote this to provide advice to people considering such update...

  You think about the amount of work that you want to post just to run Win10.  Seriously.  Old machine Win7 tend to come in two flavors when it comes to upgrading Win10 - really easy and really difficult.

  The really hard to upgrade computers fall into two categories: (1) those who are expandable to Win10 and works OK, (2) those who are not.

  Computers laptops HP, especially old Win7 machines, often came with two different graphics - and Intel chips and then either a processor AMD or Nvidia.  This was known as switchable graphics card or hybrid.  You have run using the Intel chip most of the time, but when you need additional graphics power, as in the game, the PC automatically switched over to the use of the AMD or Nvidia graphics chip.

  Problem is, this requires special graphics drivers to work, and while that those that are preinstalled on laptops Win7, these drivers simply do not exist for Win10.  These drivers are not available from Intel, AMD or Nvidia.  One way to tell if your PC has two different graphics chips is to look in under Graphics Device Manager.  If there are two different cards in the list, an Intel and AMD/Nividia, then you have this problem - and if you force an upgrade to Win10, you will have serious graphic problems and your machine will not work.

  However, if you do not have this problem, to CAN pass to Win10, but you must be willing to do four things:
  (1) do a full image backup of disk external drive or USB stick, capacity
  (2) changes to the reserved system partitioning hard disk recommandΘes mΘthodes,
  (3) use a different approach and maybe more than one, as Windows Update to do the upgrade,
  (4) prepare for a clean install.

  ---------------------------------
  1: backup of images:
  This is VITAL, because the machine is doomed to failure of the upgrade, and when that happens, you will learn that GoBack to Win10 function is NOT reliable, and that can leave you with a corrupt machine that will require the factory reset and lose all that on it, to get it working again.

  You can avoid this by making an image backup to an external hard drive or a USB drive using Macrium reflect (MR), which provides a FREE version that can be used to image and restore partitions or drives together.

  What I recommend is the following:
  (1) download and install Macrium reflect (MR)
  (2) run M. and choose the option: "Create an image of the partition (s) required to backup and restore Windows" to write a full backup to an external drive or USB key
  (3) use the option to create a CD or a USB startup key

  NOW, you have the means to restore a full system that works for the external hard drive or USB key in a few minutes.
  ---------------------------------
  2: System reserved for resizing:
  There is a small partition on the HDD with Win7 preinstalled machines known as system reserved.  It is something known as the boot loader code.  There is 100 MB format: all that is necessary for Win7.  But Win10 needs 350 MB and, in some cases, is NOT able to resize it on its own.  IF this happens, you must manually use a partitioning tool to resize it yourself.
  ---------------------------------
  3: use a different approach to upgrade:
  Windows Update is the simpler, but less reliable, way to do the upgrade from Win10.  A much better and more reliable way is to use Microsoft Media creation tool: http://windows.microsoft.com/en-us/windows-10/media-creation-tool-install?ocid=ms_wol_win10 choose the upgrade this option now PC.

  After all this, you know that MS install drivers with only the most basic features.  Given that HP does not have drivers for your PC Win10, this limited functionality is the best you're going to get.  HP does not actively write new drivers from Win10 for the old PC Win7.  To keep all the features of your PC, your best shot is NOT to upgrade to Win10.
  ---------------------------------
  4: be prepared to clean-install:
  If you do all this, and after the upgrade, your PC works partially, this means that the upgrade is not well and stuff is still there the previous OS corrupt the functionality of Win10.

  You MIGHT be able to solve the problem in fact a clean install of Win10. Problem is that, often, a clean-install does not recognize prior activation, even if it should. So, before doing the upgrade, follow these instructions on the community forums Win10 on creating a genuineticket.xml file: http://www.tenforums.com/tutorials/23354-clean-install-windows-10-directly-without-having-upgrade-first.html

  You need more later to activate your pc Win10 after the installation of clean.

  Good luck

• motherboard ms7184 upgraded to windows 8

  Hello

  thought I would try the upgrade from my old XP system directly to Windows 8. The Windows utility checks if the system is suitable for the upgrade gave a positive result. So far so good. I then tried to install it. The o/s seemed to download and install ok, but when the first restart was necessary during the upgrade, restart, Windows 8, hung on the download page. I picked up then go back to XP.

  I have Acronis like the back up and restore s/w and have the ability to run Acronis during the operating system boot sequence. I don't see why this may have an impact on the installation of Windows 8, but can be a problem.

  Is there any ideas for a fix or otherwise, I would appreciate them. Thank you.

  Hello

  I have now successfully upgraded to W8. I re-tried the upgrade and this process worked. The only thing I could think who can influence the migration (W8 bought online a few months ago a download process allowing to install - no disks) was to uninstall Acronis functionality that allowed a managed Acronis Recovery when starting. What I thought, may hinder the system restarts during the installation of W8 causing it to hang. Acronis is my back to the top and recovery s / w good it is too.

  These devices may not work properly after the upgrade. Before the upgrade, we recommend that you update the drivers for those devices. Cancel the upgrade, open the control panel and search for "update device drivers" or go to the website of the manufacturer of the device to search for updated drivers.

• upgrade to windows 7 Home premium to windows 7 ultimate

  Hi everyone im wondering if I upgrade from windows 7 Home Edition premium to windows 7 Ultimate edition will I lose the ability to restore the laptop to factory State?

  You should be able to use upgrade wizard level Express in Windows 7 Home Premium using the Windows 7 Ultimate product key.

  If the license for Windows 7 Ultimate, you have access to is a retail version update or complete, you can use the product key and the Express upgrade to Windows 7 Home Premium to Windows 7 Ultimate. 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 Ultimate edition at the request, 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 Ultimate files the stored settings and programs.

  If you decide to restore the computer to factory in the future State, it won't affect it.

  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 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"
