So by default it's going to boot off of Windows 8.1, because the BCD, the boot configuration data,doesn't know that extra hard disk drive has been added to the system that has Windows 7 on it. In that situation, if I wanted to boot the Windows 7 disk, I would have to actually access my setup program for either BIOS or UEFI depending upon which my mother board uses. In order to use the Windows 7 disk, to boot off of it, what I would have to do in this situation, is access my boot menu, and then manually specify that I want to boot off of the second hard disk in this system instead of the first. That works, but it'd sure be nice if I was just presented with a nice menu every time the system booted up and I'm allowed to pick which version of Windows I want to install. We can do that using the RebuildBcd command. You'll notice down here, that the bootrec command,using RebuildBcd, found and extra Windows installation that was not currently in the boot configuration data. This is the Windows 7 installation that is located on the G: drive. It says, "Do you want to add this in Windows installation to the boot list?" I'm going to say "Yes. Please do." And the operation completed successfully. So now I can boot either Windows 8.1, or Windows 7. Windows 8.1 is on the C: drive, Windows 7 is on the G: drive. Alright, so I've rebooted the system and because the bootrec command located the additional operating system on my G: drive, I'm now prompted, when I boot the system, to pick which one it is that I want to load. Do I want to load Windows 8.1? Or do I want to run Windows 7? I can just click on the one that I want, and the system will load. Summary 6:37-6:49

That's it for this demonstration. In this demo, we talked about the bootrec command. We first looked at the FixMbr option with the bootrec command, then we looked at the FixBoot option, and then we ended this demonstration by looking at the RebuildBcd option with the bootrec command.

    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.
