i have a relatively old seagate 1.5 TB external HDD and when i connect it to my computer and turn the computer on, i get this "message" after the motherboard screen goes away. if i start up with out the HDD, the computer will load normally. If i connect the HDD when the computer is on,. the HDD functions properly. does anyone know how i can fix it so that i can leave my HDD plugged in and have my computer boot properly? i think the computer is searching for windows on the HDD but cant find it (i have 2 SSD's in the computer, one with windows on it).

Motherboard: MSI Z97S SLI Krait edition
