This thread is magical. I was experimenting with Ubuntu awhile back and I found that I didn't want to run it on my desktop so I deleted the partition and shut down, Fast forward to 2 months later I went to power on said desktop on a lack of sleep and found that the computer was booting to "grub recuse" command. I didn't know that Ubuntu overridden the MBR with Grub. Now I do.

Found this site because I could not remember now to fix the MBR to save my life. That and I was overlooking the simplest answer to my problem.
Long story short, you saved my lack of sleep ass and I thank you for it.
