Fix #2: Confirm the Boot Order
You need to enter the BIOS utility and check if the primary boot option is the primary HDD. If not, change the boot order. Follow the steps below.

Step 2. When you have entered the BIOS Setup utility, view the options listed horizontally at the top of the screen and locate the option for changing boot sequence.
