So another option is to change the boot order in the firmware configuration and that's what we're going to do here. What I want to do is move the USB storage ahead of the internal hard disk drive. To do this we can select it and press the up arrow key. That moves the USB storage device ahead of the internal hard disk drive so now the firmware's first going to look on the floppy drive, it's not going to find anything and then it's going to quarry all of its USB ports to try to find a flash drive or an external hard drive and if that device has an operating system it will go ahead and load it, well that's what we want to do because this will then load the Windows pre-installation environment associated with the Windows 10 upgrade disk and we can go ahead and upgrade the system from Windows 7 to Windows 10. Only if the system did not find a bootable device connected to a USB port will it then boot off of the internal hard disk drive. So we've made this change, we should be good to go. Boot Options 5:57-6:56 Notice over here that we do have the option of enabling or disabling various boot options as well. For example, I just turned off the floppy diskette drive. Because frankly floppy disk's are useless. They don't hold enough information and I haven't booted an operating system from a floppy disk drive since about 2005. So, I'm going to turn that option off, I don't want the system to even look at the floppy disk drive. I can also come down here and turn off the network boot, the pixie boot option. For security reasons I may not the system to go out on the network and try to boot an operating system from a network server. So now, I'm only going to use three devices for booting, I'm going to use my USB storage device first and only if one is not connected with an operating system installed will it boot off of the internal hard disk drive and then nothing's found there it will try to boot off of the CD or DVD drive.So let's go down here and hit apply and the changes are now made. So at this point, I can come down here and click exit and then reboot the system and it'll boot off of my USB drive. Security Risks 6:57-8:30 Now before we end, I need to point out that there are security risks with having this option and this option enabled. As I said a minute ago with the USB drive, boot option enabled and set to the beginning of the boot order. That means that I can of course run my Windows 10 upgrade installer from the USB drive but it also means I could run any operating system I wanted to off of the USB drive and if you had the malicious insider or maybe even an attacker who managed to gain access to your facility and gain access to this system, they could insert a USB drive into a port on this system that has some other operating system installed like Linux, boot the system from the USB drive and grab a copy of my internal hard disk drive using a disk imaging tool like DD, which is really easy to doand then be able to walk out the door with the contents of this computer system safely and securing stored on a USB flash drive and no one would be the wiser.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
