I installed Kali on a one of my 3 partitions just fine, booted into windows 8.1 though just fine, but my partition that I shrunk to fit Kali on was no longer visible. I went to disk management and noticed that my partition wasn't "Active"....So what did I do....I activated it, ignoring the warning that I shouldn't activate it unless there is an OS present on that partition. I'm an idiot. That partition only had my data on it, not the windows install....so now I rebooted (for the changes to take effect) and am now in the Grub Rescue mode. I have no clue how to "deactivate" that partition, someone please help so I can use my computer again!

Edit: I can still probably boot from my USB LIVE Kali however I have no clue what to do from there.....
