HP Envy tower- will not restart with external HDDs attached

[Firsty]

When I attempt to reboot while I have any external HDD (no OS installed) attached to the machine, it will not reboot.  No BIOS screen, no error messages; the screen simply goes to black and will not complete the reboot cycle.  I have to disconnect the HDDs, do a hard shutdown, and power it up again.

This happened while I had the original factory HDD in the machine.  I later bought a SSD and installed a clean OEM Windows 10 64-bit, and I still have this same problem.  If I have no external HDD attached, the machine reboots properly.

I went into the BIOS and changed the boot device order so that it would look to the internal HDD first, and I still have this issue.

@Firsty, welcome to the forum.

I had a similar problem using Win 7.  I went to the HDD manufacturer's website and installed a firmware update.  This solved my problem.  It may be that the drives are not compatible with Win 10.

Nice tip @old_geekster I remember a thread from several years ago with this problem and couldn't remember what the resolution was. Hopefully this will solve it for @Firsty
