Thank you for your time!As you can see in debian_04.jpg , the Debian that was recently installed in the hard drive is unbootable.debian_02.jpg and debian_03 show the two different Boot Priority that I tried. Both resulted in the last file, debian_04.jpgdebian_01.jpg shows how I formatted the brand new hard drive. My goal is to install Debian first, then Windows. I know it's not the better way to make a dual boot system, but I just want to try.Hello Friends!Are my attached files too big? If so, let me know, I'll make them smaller next time.
