Upgrading to Windows 7
This document pertains to HP and Compaq desktop PCs.
HP is committed to helping you upgrade your HP or Compaq computer to Windows 7. This document is about installing Windows 7 on HP and Compaq desktop computers. It provides instructions to help guide you through the installation process.
CAUTION:Before installing Windows 7, back up important files and make sure you have HP System Recovery discs!
Important information about installing Windows 7
There are two methods to install Windows 7 onto a computer:
- Upgrade - installs Windows 7 over an existing Windows Vista installation. 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 Vista Home Basic, Home Premium, Business or Ultimate Edition with Service Pack 1 or 2.
- Custom Install - erases all files on the hard drive partition before installing Windows 7. Any computer that meets the minimum hardware requirements can use Custom Install to install Windows 7. Your software programs, drivers, and files are no longer available after using Custom Install. Make sure to backup important files before doing a Custom Install!
Minimum System Requirements
Your computer hardware must meet the following minimum system requirements before you can install Windows 7.
Minimum hardware requirements
- 1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor
- 1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit)
- 16 GB available hard disk space (32-bit) or 20 GB (64-bit)
- DirectX 9 graphics device with WDDM 1.0 or higher driver
To test your computer for Windows 7 compatibility, see Microsoft's Web page on Windows 7 system requirements .
Operating System requirements
Installing Windows 7 using Custom Install does not require an operating system on the hard drive. A custom Install removes all files from your hard drive partition and installs Windows 7. If your computer currently has Windows XP, Windows Vista Home Edition, Windows Vista Starter Edition, a prerelease version of Windows 7 (beta or RC), or any other operating system, you can use Custom Install to install Windows 7.
Upgrading to Windows 7 requires Windows Vista Home Basic, Home Premium, Enterprise, Business, or Ultimate with Service Pack 1 or 2 on the hard drive. The language type for the Windows 7 upgrade disc must be the same languages type as your version of Vista.
|Vista edition on your computer||Upgrades to one of these Windows 7 editions|
|Home Basic||Home Basic, Home Premium, or Ultimate|
|Home Premium||Home Premium, or Ultimate|
|Business||Professional, Enterprise, or Ultimate|
Using the HP Upgrade Assistant DVD
If you participated in the Upgrade Option Program from HP and you obtained a disc, this DVD contains most of the software and drivers needed for upgrading HP and Compaq Desktop and TouchSmart computers to Windows 7. This useful disc came with the Windows 7 upgrade kit if you ordered the Windows 7 upgrade from HP.
NOTE:The Windows 7 Upgrade Option Program from HP is no longer accepting new orders.
To use the disc, insert it into the drive while Windows Vista is open and follow the information that appears. Later, after installing Windows 7, insert the disc again to get the latest updates.
This disc can help speed up the time it takes to find software and drivers. However, the HP Upgrade Assistant DVD is not required, nor does it contain all available updates for all HP computers.
NOTE:If you are using the HP Upgrade Assistant DVD, after successfully upgrading to Windows 7, do not connect to the Internet. Unplug the LAN cable, do not set up your wireless LAN, and do not connect to the Internet using a modem. Connect to the Internet only after you have completed Phase 3: Post Install by running the HPUA icon on the desktop and have restarted your computer. This is necessary to prevent driver and software update conflicts that can arise between the HP Upgrade Assistant DVD, Windows Update and HP Update.
Preparing the computer for Windows 7
Use the steps in this section to prepare your computer for Windows 7.
NOTE: If you participated in the Windows 7 Upgrade Option Program from HP and have an HP Upgrade Assistant DVD, insert the DVD now and follow the instructions that appear.
Step 1: Update the BIOS
Use the following steps to update the BIOS to avoid installation problems.
- Turn on the computer and immediately press the F10 key repeatedly until a BIOS Setup Utility screen opens. Some computers use F1 instead of F10.
- Write down the BIOS revision number from the main page (not from the bottom of the screen).
- Go to the HP Support Web site ( http://www.hp.com/support ), select Software and Drivers, and enter your computer model number to find software and driver updates for your computer.
- If a BIOS update is available that has a higher revision number, download and install it following the instructions on the Web site.
For more information about updating the BIOS, see Updating the BIOS .
Step 2: Find software and driver updates compatible with Windows 7
Get all available software and driver updates as follows:
- Download Windows 7 software and driver updates for your computer from HP (SoftPaqs) and store them on a USB drive or burn them to disc. For more information on downloading software from HP, see Obtaining Software and Drivers .
- If you are upgrading, see Updating Drivers and Software with Windows Update and install all Important and Recommended updates. Also, install all optional updates. When you have finished installing Windows updates, restart the computer and continue installing Windows Updates until it displays "Windows is up to date". If you are using a Windows Vista version that is not Service Pack 1 or better, install Windows Vista Service Pack 1 (SP1). You do not have to install Windows Vista SP2.
- If you are upgrading, download and install the latest antivirus and antispyware definitions for your security software. After you have installed the latest definitions, use your security software to scan for malware. Fix any problems that are found.NOTE: If you are using AVG 8.0 Security Software, you need to upgrade to a Windows 7 compatible version to keep your current program subscription. AVG 8.0 comes with HP Firebird computers and is not compatible with Windows 7.
- If you are upgrading, download and install the latest HP SoftPaqs for Windows Vista. For more information on downloading software from HP, see Obtaining Software and Drivers .
Step 3: Recovery and backing up your important files
If you have not already done so, create a set of system recovery discs. If a problem occurs during installation, you can use recovery discs to return your computer back to its original software configuration. If you cannot find your recovery discs, see Looking for Recovery Discs?
Back up your important files. You can copy all your files to CDs, DVDs or other external storage device. You may also use Microsoft Backup and Restore Center or Microsoft Windows Easy Transfer to back up your Windows files and transfer them to Windows 7. Windows Easy Transfer is compatible with XP, Vista, it comes with Windows 7 and Microsoft has provided updated versions of Windows Easy transfer for Vista and XP that makes backing up files easy.
When finished, verify that the backup was successful and that you can access your files using your current operating system.
For more information about using Windows Easy Transfer, see Microsoft's Web page on Windows Easy Transfer (in English).
For more information about using Microsoft Backup and Restore Center, see Microsoft's Web page on Explore the features: Windows Backup and Restore Center (in English).
Do not use backup software that is incompatible with Windows 7! If you want to backup your files using other software, you must first verify that it is compatible with Windows 7 before using it. You will also need a copy of the software's installation files on a USB drive or disc.
Step 4: Make sure that BitLocker Drive Encryption is disabled
Some versions of Windows Vista contain a BitLocker Drive Encryption feature. If you are upgrading to Windows 7 over an existing Windows Vista installation, make sure that the BitLocker Drive Encryption feature is disabled.
In Windows Vista, the term disable refers to the process of temporarily suspending BitLocker protection on a drive—without decrypting the drive. Disabling BitLocker suspends the authentication mechanisms used by BitLocker and uses a clear key on the drive to enable access.
- Click Start , and then click Control Panel.
- Click Security.
- If BitLocker Drive Encryption does not display in the right-hand panel, your version of Windows Vista does not contain this feature.
- If BitLocker Drive Encryption displays in the right-hand panel, click it.
- If Off displays under the Volumes section, BitLocker is turned off.
- If On displays under the Volumes section, BitLocker is turned on and must be turned off. To turn BitLocker off, click Turn Off BitLocker, and then click Disable Protection.
- When the upgrade to Windows 7 is complete, open Windows Explorer, right-click the drive, and then click Resume Protection. This reapplies the BitLocker authentication methods and deletes the clear key.
