Hi Bob,

To better assist you, do let us the complete message that you receive.

Sometimes, this could be due to two operating system installed in your computer. Just to make sure this is not the case, I suggest you to try the steps below:

1. Press Windows key + R.

2. Type msconfig and press enter.

3. Click the "boot" tab and check if there are any other operating system listed.

4. In addition, change the timeout time to 3 seconds(default)

Let us know the result, we will be glad to help if you need further assistance.
