Upgrading from Windows 7 to Windows 8

  • PrintPrint
This document pertains to HP Desktop and All-in-One computers to be upgraded from Windows 7 using a digital copy of Windows 8. . You perform either an In-place Installation that retains your data and settings from Windows 7, or a Clean Installation (custom) that deletes all data from the hard drive before installing Windows 8.
Please read the following important information before beginning your upgrade:
  • Not all Windows 8 features are available on all Windows 7 computers. Your computer might require additional hardware, software, firmware, and/or a BIOS upgrade to install and run Windows 8.
  • Secure boot is not available on any HP Consumer Desktop or All-in-One computers.
  • HP provides upgrade instructions and drivers for most computers sold after October 1st , 2011.
  • For information about the Microsoft Windows 8 Upgrade Offer go to www.windowsupgradeoffer.com and www.windowsupgradeoffer.com/en-US/Home/Faq . Check these sites frequently, as details change or additional information becomes available.
  • If you purchased your computer prior to October 1st , 2011, HP has not tested or developed drivers for your model computer. Therefore an upgrade of your computer might be difficult or impossible.
  • HP recommends installing the 64-bit version of Windows 8 for desktop computers.
  • Not all Windows 8 features will be available on all computers, and your particular experience with Windows 8 is determined by the capabilities of your computer.
  • An In-place Upgrade is easier and faster than a Clean install and is the better option for most people. See below for help determining the best method for your particular computer.
  • Software designed for Windows 7 or earlier operating systems might not work after installing Windows 8.
  • HP provides Windows 8 compatible software and updated drivers to support only specific computer models.
  • If you want to restore the original operating system after upgrading, you must create HP recovery media before you upgrade. To learn how to create recovery media, see Creating Recovery Discs or Saving a Recovery Image to a USB Flash Drive (Windows 7) .
  • If you seek support assistance from HP after you upgrade, HP technical support may request that the original Windows 7 operating system be restored to verify product functionality. If your computer is sent to service or repairs after upgrading to Windows 8, your computer may be re-imaged with the original Windows operating system and the upgraded Windows 8 operating system will be removed. After repairs are made, you can reinstall Windows 8.
  • You should always back up all important data (personal files, photos, videos, documents, applications, etc.) before beginning any upgrade to avoid any possibility of losing your important data.
  • You might not be able to view DVD movies after upgrading. If you currently use a DVD codec to play DVD movies, such as the encoder that comes with Windows 7 Professional, this encoder might not be available after upgrading to Windows 8. To continue to play DVDs after you upgrade, go to http://windows.microsoft.com/en-US/windows-8/feature-packs to download Windows Media Center or purchase DVD playback software.
    If you currently use DVD playback software from HP, the Windows 8 installation process helps you determine if your playback software is compatible with Windows 8 or if an update is required. If the software is compatible and you perform an In-place Upgrade, you have the option to keep this software during the upgrade. If you perform a Clean Install you must reinstall the software after the upgrade.

System Requirements

Microsoft requires that your computer hardware must meet the following system requirements before you can install Windows 8.
Windows 8 works on the same hardware that powers Windows 7:
  • 1 gigahertz (GHz) or faster processor
  • Minimum 2 GB RAM (64-bit), 4 GB preferred for full functionality
  • Minimum of 20 GB of hard drive storage available before installation
Additional requirements to use certain features:
  • Windows 7 computers with touch will not have full Windows 8 touch capabilities after upgrade. HP computers with touch input hardware designed for Windows 7 will provide a comparable experience only for two touch point applications after the upgrade to Windows 8. HP Windows computers with touch input hardware will not support Windows 8 applications that require more than two simultaneous touch points.
    WARNING:HP Linkup, HP Application Assistant, HP TouchSmart Magic Canvas and all other HP TouchSmart applications are not compatible with Windows 8 and must be uninstalled before upgrading. Content created using the TouchSmart applications such as Graffiti will not be available after upgrading.

Determine the best method for upgrading your model computer to Windows 8

There are two methods to install Windows 8 onto a computer:
WARNING:You must back up all important data (personal files, photos, videos, documents, applications, etc.) before upgrading to avoid any possibility of losing your data.
  • In-place Upgrade - installs Windows 8 over an existing Windows 7 installation. This is the easier and faster method to upgrade and is the better option for most people. Most or all of your existing software programs, drivers, and personal files are available after upgrading. You can only perform an Upgrade if your computer has Windows 7 Starter, Home Basic, Home Premium, Business or Ultimate Edition, and some models require an upgraded BIOS Version.
  • Clean Installation (custom) - erases all files on the hard drive and removes any hard drive partitions before installing Windows 8. If your computer meets the minimum hardware requirements from Microsoft, you can use a Clean Installation. However, the original drivers and programs provided by HP and any other software you installed, will no longer be available.

Prepare your computer for In-place Upgrade method

This installation option prepares your computer for upgrade and installs Windows 8 over an existing Windows 7 installation. Most or all of your existing software programs, drivers, and personal files remain available after upgrading.

Step 1: Update the BIOS
