A while back, I installed Windows 8 on my MacBook Air (mid 2013 model) using Bootcamp. It never really worked, (it would freeze all the time, the WiFi would cut in and out, etc.) so I got rid of it. I tried to do this through Bootcamp again, but for whatever reason this didn't work, so I booted up on a live Ubuntu USB and manually erased the NTFS partition for Windows.
Once back in OS X (Mavericks, but it was Mountain Lion when I installed Windows), I expended the default HFS+ partition to fill the full space of the SSD. So now I've got a nearly out-of-box Macintosh HD partition; everything on the Mac side works fine.
But lately, I find myself getting increasingly annoyed at the BSD coreutils among other things, and so I'd like to be able to dual boot into some version of Linux (probably Ubuntu or Xubuntu, but this is kind of arbitrary).
So but it turns out that when I "uninstalled" the Windows partition, something didn't quite update in the boot loader (I'm kind of fuzzy on my knowledge of the difference between a boot loader and a boot manager, so I might be using these terms incorrectly). When I start up my Mac holding down
option, I get the following...
which is weird because this is what my main hard drive looks like in Disk Utility
and again with

To Be Fixed
I can't see where these icons would be coming from. In the end, I'd like to just have both of these gone (and I guess any other hidden remnants of Windows that they might be indicating).
