PC won't boot

[ABowman]

We set up our HP Pavilion All-in-One satisfactorily and install a few programs.  However, when we next turned it on, it beeped for over a minute.  Then a window popped up stating that there was an Unsupported Adapter Found.  There was "Press ESC for Start Menu."  Pressing ESC accomplished nothing.  Then the PC shut down.

I found this completely mystifying.  We don't have a recovery disk.  I tried to order one but found there isn't any.

Pressing F11 didn't help.  Is there anything I can do?  It is under warranty, so we could take it back.

I solved the problem.  I had plugged in a portable drive that I later removed.  What apparently happened was that the system remembered that drive.  When I tried to boot without it I got the error message.  Today I plugged that drive in and booted.   It worked and the PC booted.

Now I need to find a way to makeit  forget about that drive.

Hi @ABowman,

Welcome to HP Forums, this is a great place to get support, find answers and tips.

Thank you for posting your query, I'll be more than glad to help you.

I understand that your computer does not boot without inserting the portable hard drive and you wanted to know how to stop it.

This issue could occur if the USB drivers are not updated.

Let's go through a few steps to troubleshoot this issue.

And here's the step by step guide for you listed below to update the USB drivers from the device manager.

1. Open Device Manager.

2. Double-click the type of device that you want to uninstall.

3. Right-click the specific device you want, and then click Uninstall. You can also double-click the device, and then on the Driver tab, click Uninstall.

4. In the Confirm Device Removal page, select Delete the driver software for this device.

5. Click OK to complete the uninstall process.

6. Restart the computer.

Let me know how this works.
 

You have a good day ahead.
