When my pc is inserted with a USB flash drive, the pc does not boot up and
stuck unless I change the boot sequence from USB device->DVD drive->hard
disk to DVD drive->Hard disk->USB device. What does the system look for as
the USB flash drive is not a bootable one? In general, it should skip to
DVD drive and skip to hard disk if there is no bootable disk in DVD drive.
Is it a hardware issue or OS issue or bios issue? Your guidance is
