Hi @Muskid,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

When your HP system displays a "Non-system disk" error message upon booting, it typically indicates that the computer is trying to boot from a storage device that doesn't contain an operating system. This could happen due to several reasons, such as incorrect boot settings, a malfunctioning hard drive, or a disconnected external storage device. Here’s how you can troubleshoot and resolve this issue:

1. Remove External Devices

1. Disconnect All External Storage: If you have any USB flash drives, external hard drives, or CDs/DVDs inserted, remove them from your computer and restart.

2. Check Boot Order in BIOS/UEFI

Access BIOS/UEFI: Restart your computer and press the key (usually Esc, F2, F10, or Del) to enter BIOS/UEFI settings.

Check Boot Order:

• Navigate to the Boot menu.
• Ensure that the internal hard drive (usually labeled as SATA or NVMe) where your operating system is installed is set as the first boot device.
• Disable any other devices that may be listed as higher priorities but don’t contain a bootable operating system.

3. Check Hard Drive Connections

1. Ensure Proper Connections:
   • If you recently installed new hardware or were working inside the computer case, double-check that all cables connected to your hard drive (SATA or power cables) are firmly seated.

4. Run Hardware Diagnostics

• Many HP computers have built-in diagnostic tools that can help identify hardware issues.Restart your computer and press Esc or another designated key to access the diagnostics menu.

5. Repair Master Boot Record (MBR)

1. Use Windows Recovery Environment:
   • Boot from a Windows installation USB or DVD.Choose your language preferences, and then select "Repair your computer."Navigate to Troubleshoot > Advanced Options > Command Prompt.Type bootrec /fixmbr and press Enter.Restart your computer and see if it boots properly.

6. Check for Hard Drive Failure:

• Boot from a Windows installation USB or DVD.Go to Command Prompt as described above.Type chkdsk C: /f /r (replace C: with your system drive letter) and press Enter.Allow the disk check to complete and fix any errors found.

7. Reinstall Windows:

• If none of the above steps work and you have important data backed up, you may need to reinstall Windows.Boot from a Windows installation USB or DVD and follow the prompts to reinstall the operating system.

I hope this helps.

Take care and have a good day.
