When requesting assistance, please provide the complete model name and product number (p/n) of the HP computer in question. HP/Compaq makes thousands of models of computers. Without this information it may be difficult or impossible to assist you in resolving your issue.
The above requested information can be found on the bottom of your computer, inside the battery compartment or on the startup BIOS screen. Please see How Do I Find My Model Number or Product Number? for more assistance locating this information. DO NOT include your serial number. Please enter the model/product information into HP's Online Consumer Support page and post it here for our review.
1) If you are having start-up problems, your computer may be experiencing hardware issues or failures. Please run the hardware diagnostics and test the computer for hardware issues.
2) If you want all of the HP value-added software and customizations that were originally included with your computer, you will need to return the computer to a factory like state using the HP Recovery Discs you created when you first setup your computer. If you didn't create your HP Recovery Media when you first setup your computer, please contact official HP Customer Support in your region / country, via the HP Worldwide Support Portal, to see if HP Recovery Media is available for your computer. Software may not be covered by the warranty and there may be a charge for the HP Recovery Media.
3) If you don't need the HP customizations or don't have your HP Recovery Discs, you should be able to install Windows 7 using the HP Windows 7 Upgrade Media. Using this method, you shouldn't need to use the "HP Upgrade Manager / Assistant" disc. Just place the "HP Windows 7 Upgrade Media" and boot the computer from the CD/DVD drive. This should start the installation process. Follow all prompts and answer all questions as needed. You will need to enter the Windows 7 product key that is on the Microsoft COA that came with the upgrade discs. See example below;
If you have any further questions, please don't hesitate to ask.
