“Non-system disk or disk error replace and strike any key when ready”

When I power on my HP Compaq Pro 6300 Small Factor form computer, It says Non disk error, I have entered the BIOS and tried to move hard drive to the first boot option but the problem there, I also tried to reboot windows with a USB but it says the same thing, Is there anything else I can do beside breaking apart the computer?

That error usually means that something is interfering with the boot loader.  The possibility is that there is something in the DVD/CD drive or a card is in the media slot.  Check both to verify they are empty and try again.

Or

There may be more than one drive or a floppy disk (on a PC that old) that has interfered with the boot loader.

Where is the media slot located?

[TheOldMan]

Usually it would be on the front face.  In looking at pictures of that model, it might not have a media card slot since it is a SFF.

In order to get the message about a Non-system disk, the boot loader has been unable to find the correct information to proceed with the boot-up.  It is usually because the disk it found does not have the correct boot loader information or is corrupted.  Is there another drive or device connected that would/could be causing this?

Thank you so much for your help, I figured out that one of my cords were lose and plugging that cord back in removed the message and restored my computer!😁 (Im gonna accept your first reply so it can help someone)
