    Here is my new boot info from the boot repair application.
    http://paste.ubuntu.com/5634045/

    I KNOW I told it to install GRUB to sda in the drop down menu on the bottom when I was creating partitions for the Ubuntu OS and swap files.

    Hell, I did this twice and told it to install to sda1 that was the same partition as the windows bootloader.

    But, for some reason, there it is again, all the way in sda6.

    Try installing to /dev/sda not /dev/sda1. If you cannot, then you might have problems.
    Also, make sure that an Ubuntu partition is actually flagged as bootable.

    Do you mean to mount it as /boot and not /?

    Or do you mean to create ANOTHER partition of x size and make it an ext4 /boot partition?

    No.

    There are many parts to grub. You just want the boot loader part in the MBR as computers (in BIOS mode) only boot from the MBR. The MBR code then redirects to more boot code. Never install grub to a NTFS partition.
    If you want to understand how MBR booting works just review pictures:

    But you are showing grub4dos in your Windows partition. Are you trying to use EasyBCD?

    You also need to be booting live installer or repair disks in BIOS/legacy/CSM mode, not in UEFI mode. Then run the repairs Boot-Repair suggests, but not if in UEFI mode.

    I'm an idiot. I was hitting F8, going to the boot selection screen. It had UEFI: <My USB Stick> and I was clicking that because it was my very first choice, but there are other choices available.

    Also, yes, I attempted EasyBCD at one point, but it didn't work.

    Well that was my problem. Didn't fully understand the implications of UEFI. Booting it regularly solved all my problems and I just made this post on my brand new, WORKING, Ubuntu OS.

    Thanks for all your help. :3

    Also, for anyone that may not understand what I just did and has the same problem.

    In the boot menu where I could select my USB to install Ubuntu from, there was one option that literally had "UEFI:" before the USB stick name. Don't pick that one. That will apparently tell your PC to NOT put GRUB in sda.
