HP PCs - Error: The Boot Selection Failed Because a Required Device Is Inaccessible (Windows 8, 7)

This document applies to HP computers with Windows 8 or Windows 7.
Windows fails to start, and an error message appears: The boot selection failed because a required device is inaccessible.
When your computer starts, the system BIOS begins to check a pre-determined list of drives and devices that might contain an operating system (Windows 8 or Windows 7). Normally, the computer boots from your primary hard drive, or a boot device that you have selected, where the operating system is stored. If the boot device is damaged, or if the computer attempts to boot from a different device, the operating system does not start up and you receive an error message.
There are numerous possible causes and solutions for this error. Use this document as a guide through the troubleshooting process.
Step 1: Check the computer cable connections
Make sure that all computer cables are connected properly to the correct ports. Check the connections at both ends of each cable. If you recently moved a cable to a different port on the computer, move it back to the original port, if possible. When finished, restart the computer.
Step 2: Remove all external devices
Use the following steps to identify whether an external device is causing the error:
  1. Disconnect all peripheral devices from your computer (for example: printers, memory card readers, external hard drives, and external CD/DVD drives), except the keyboard, mouse, and monitor (if applicable).
  2. With all devices disconnected, restart the computer.
  3. If the computer starts normally, it was attempting to boot from one of the external devices. Reconnect the devices one at a time, restarting each time, to identify which device was causing the problem.
Step 3: Select a different boot device
The boot order might have been changed, or a partition was added or removed, causing the computer to attempt to boot from the incorrect device or partition. Reset the default boot order or select a different boot device using the steps in the appropriate section for your computer:
 note:
The steps for modifying the boot order can vary depending on the computer model. Use the following steps as a guide while paying attention to the on-screen instructions. BIOS settings for boot order are generally found in the Maintenance and Service Guide, available on the HP product page for your computer model.
Step 4: Use the bootrec.exe tool in the Windows Recovery Environment
If you have the Windows installation disc that came with your copy of Windows, or if you created Windows recovery media (DVDs or USB drive), use the bootrec.exe tool to troubleshoot and repair the Master Boot Record.
Step 5: Restore Windows to a previous point
If the computer detects an operating system on the hard drive, you might be able to restore Windows. System Restore will undo any recent changes that might be causing the blue screen error, including changing your settings and uninstalling recently-installed software applications.
 note:
On most computers, System Restore points are created by default. Restore points might be disabled, depending on your configuration. Continue to the next step if system restore points are unavailable.
Step 6: Test the hard disk drive
Use the instructions in one of the following sections to test the hard disk drive in your computer:
If the results indicate the hard drive has failed, the hard drive might need to be replaced. Have the computer serviced, or find the hard drive replacement procedure in your product's Maintenance and Service guide, available on the HP product page for your computer model.
If the hard drive is working normally but Windows still does not boot, proceed to the next troubleshooting step.
Step 7: Perform an HP System Recovery
If a new hard drive was added, hard drive partitions were created or removed, or you installed a different operating system, and if none of the previous troubleshooting steps have corrected the error, you might need to perform a recovery on your computer to fix the error. Use the steps in one of the following HP support documents to perform a system recovery:
