internal drive in your HP EliteDesk 800 G5

 If the internal drive in your HP EliteDesk 800 G5 is failing and you want to boot from a USB external hard drive, you can set it up in a few steps. This will allow you to use an external drive as your primary boot device, bypassing the internal drive.

Here’s how you can do that:


1. Prepare Your External USB Drive

  • First, make sure your external USB drive is properly formatted and has enough space to hold your operating system (OS).
  • If you don’t already have an OS installed on it, you’ll need to create a bootable USB drive with Windows or your desired OS.

Create a Bootable USB with Windows:

  1. Download Windows Media Creation Tool from Microsoft’s website:
    https://www.microsoft.com/en-us/software-download/windows10
  2. Insert your external USB hard drive into a working computer.
  3. Open the Media Creation Tool and choose the option to create installation media.
  4. Follow the prompts to create a bootable USB.
  5. Once complete, connect the external drive to your HP EliteDesk 800 G5.

2. Enter BIOS/UEFI Settings

  • Turn off your HP EliteDesk 800 G5.
  • Turn it back on, and press F10 immediately to enter the BIOS/UEFI settings.
  • In the BIOS, you will adjust the boot order to prioritize your external USB drive.

3. Change Boot Order in BIOS

  1. Navigate to the Boot Menu:
    In the BIOS, find the Boot tab or section (it could also be under Boot Options).

  2. Change Boot Order:
    Set the external USB hard drive as the first boot device. This will make your PC boot from the external drive before trying to boot from the internal one.

    • Typically, you can move devices up or down using arrow keys (refer to the instructions in the BIOS if unsure).
  3. Save and Exit:
    Press F10 to save the changes and exit the BIOS.


4. Boot from the External USB Drive

  • After saving your changes, your HP EliteDesk 800 G5 will attempt to boot from the external USB hard drive.

  • If you created a bootable Windows USB, the system should start the Windows installation or boot into the OS on the external drive.

    • If you're using a USB hard drive with a fully installed OS, it will boot directly into that OS.

5. Install/Transfer Windows (Optional)

  • If you're using the external USB drive as a temporary boot device, you can install Windows or migrate your data to the external drive while you wait for a replacement internal drive.
  • Use Windows Backup and Restore or Clonezilla (for cloning) to transfer data from the failing internal drive to the external USB drive if needed.

Troubleshooting Tips:

  • If the external USB hard drive doesn’t appear in the BIOS boot menu, try a different USB port (preferably a USB 3.0 port) on your HP EliteDesk 800 G5.
  • Ensure that the USB drive is properly formatted as a bootable device and has an operating system installed.
  • Check for Secure Boot settings in the BIOS: If it’s enabled, you might need to disable it for booting from an external drive. Go to the Security tab in BIOS and turn off Secure Boot.

Conclusion

By setting your external USB hard drive as the primary boot device in BIOS, you can successfully boot from the external drive instead of the failing internal one. This solution is perfect for accessing your system while waiting for a replacement drive or if you want to use the external drive for a fresh OS installation.
