    You got the error because you are running Power Shell and not a Command Prompt. I believe, in Power shell you have to replace the %...% with $ENV:

    bcdedit /enum all > $ENV:userprofile\Desktop\bcdtext.txt

    You also need to run it as an administrator, so select that option.

    It is easier to download: Download Visual BCD
    and delete the entry from the GUI interface instead of using bcdedit.

    NOTE: The program will popup an error at the beginning, just ignore it.

    Okay, I tried re-entering both of those command lines, one in the power shell and one in the command prompt, both run as administrator, and I didn't seem to get any results back. Any thoughts on why that would be? I think I'll take a look at that visual BCD later today as well.

    Huh, that was interesting. The file wasn't there a minute ago, but I did a quick search for it and suddenly it appeared on my desktop. Here are it's contents:

    From your post above, the identifier for UBUNTU is: {510e8171-16ce-11e4-8279-806e6f6e6963}
    so if you wish to use visualBCD, download and install it:
    1. Run visualBCD
    2. Press F4 to make a backup of the BCD Store
    3. Go thru the list and delete the entry with the identifier: {510e8171-16ce-11e4-8279-806e6f6e6963}
    4. Here's an example of my Windows 8.1 entry. You would look for the entry with description: Ubuntu and delete it.

    Update: I downloaded Visual BCD, and I found and deleted Ubuntu and all of its contents, but, after restarting my computer, it's there again. This thing is persistent! I think I'm just going to throw in the towel and leave it there. I don't imagine it will be doing any harm.

    Perhaps some things are just meant to be... LOL

    I do however recall Saltgrass and SIW2 posting instructions regarding formatting the EFI partition and rebuilding with bcdboot - they would know better than me though.

    One more thing to try: Win+R->Run->msconfig
    click on boot tab and check if there's an entry for Ubuntu there then delete it.

    Haha, yeah, my thoughts exactly. Who knows, I may end up trying to re-install Ubuntu on this machine some day anyways. At any rate, I think GRUB has proven itself worthy of remaining where it is for the time being.

    Topgundcp—I tried the msconfig suggestion, but only the windows bootloader was present..

    Thanks for all the help everyone! You guys are awesome.
