Update: I have resolved one of my problems myself, but still need help to delete a partition. I left the original post intact in case someone has a similar issue and can quickly reference this post.
Original Message: I have uninstalled Ubuntu from my main machine, but am having difficulty restoring the boot back to the Windows 8.1 default.
I followed a guide from http://itsfoss.com/uninstall-ubuntu-linux-windows-dual-boot/ but I could not complete all the steps entirely. There was a single partition (which exists on my sole disk, with my C: volume) that I cannot delete (type *:SYSTEM) because, according to Windows, it is currently in use. I then followed the rest of the guide having skipped deleting that one partition.
Now, however, I find that whenever I restart my machine, it boots to a "minimal" version of grub were I can enter some basic commands. If I type exit twice (for some reason there is always an error the first time) it exits Grub and proceeds to boot like it normally should.
What I have tried:
- Using Windows Disk Management to remove it (results in the error stating the partition is in use)
- Using AOEMEI Partition Assistant Edition 5.6 (the option is grey)
- Contemplated using the 'clean' command in 'diskpart' after selecting the partition as my focus. But every source I found said that 'cean' cleans the entirety of the selected disk, not the actual focus.
- Repairing Windows from the installation flash drive I made
- Praying to the Old Gods
- Tried finding some way to delete the disk from the command prompt at boot, but to no avail.
- Revisited diskpart and used 'delete partition override' but received an error iterating what the Disk Manager said.
Any help/instructions would be greatly appreciated at this point.
Here are some images of my partitions:

The partition I've been trying to delete is the partition without a File System (Windows Disk Management) which is the one listed as *:System with File System FAT32 in AOMEI. Thank You.
