I’m inclined to agree w/Wanyne. It’s odd, however, that a motherboard would by defaut choose to boot from USB drive instead of an internal drive.
Don’t be afraid to hit “F1” and review your BIOS settings. Look for anything having to do w/USB and/or the order in which the boot drives are listed and report back here. Then press “Esc” and selected NOT to save your settings. Someone might be able to then tell you how to solve your problem.
BTW, what model ASUS board are you using? Asus posts the manuals for many of their boards on their website. Someone looking at your question might be able to help you better by reviewing the BIOS settings listed in the manual.
