This is NOT official HP Customer Support and I, as most other persons on this forum, do not work for HP. This is a peer-to-peer user supported forum for HP consumer class products. HP maintains no official presence on this forum and it is unlikely that HP will respond in an official capacity. Any reply from a HP employee represents their own opinion and not that of HP's.
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.
Please indicate what you have tried and what you mean by " I can't get it to upload the downgrade."
Make sure you create your HP Restore / Recovery Discs or USB Flash Restore / Recovery Media before modifying or changing ANYTHING.
You will need to DISABLE "Secure Boot" and ENABLE "Legacy Support" in the "BIOS Secure Boot configuration" page on the settings page shown below, before you can attempt to install Windows 7;
or
Additionally, as the hard drive may be partitioned as GPT, you may have to boot the computer using the "UEFI - CD/DVD drive" or "UEFI - USB Flash drive" options in the "F9" boot menu. If "UEFI - CD/DVD drive", "UEFI - USB Flash drive" or something to that effect doesn't exist in the boot menu, please post a screen shot and/or descibe the listed boot options.
I suggest using Windows 7 SP1 for the best intallation experience. If you need Windows SP1, please see "How to Install Windows 7 Without the Disc" to download and create your own Windows 7 SP1 disc. If the DVD refuses to boot as UEFI, you may need to use a USB Flash drive (may require DISABLING "Fast Boot" and/or setting "USB 3.0" to "AUTO" in the BIOS) as the installation media. Please download the Windows 7 USB/DVD download tool to create a Windows 7 SP1 USB Flash drive. Please note that some computers may not recognize a valid UEFI enabled USB Flash drive if it is formated as NTFS and may require a FAT32 formatted USB Flash drive. You should be able to make a FAT32 formatted Windows 7 installation USB Flash drive using Rufus, UNetbootin, Universal USB Installer, or WiNToBootic. I like Rufus, as it has options for "GPT partition scheme for UEFI computer" and "FAT32".
Assuming you have a HP ProBook 650 G1 Notebook Computer, it is a business class computer and as such, your questions may be better answered in the HP Enterprise Business Community. You may also consider contacting the HP Business Support Center to request assistance with your issue.
If you have any further questions, please don't hesitate to ask.
