The error appears right after the POST process is completed and Windows starts to load. The POST is a set of routines that are run immediately when starting the PC, such as checking if your RAM, peripheral devices and other hardware components your PC has are working correctly. After these routines are completed by BIOS, the Windows boot loader begins, where this error is going to appear.
