"BOOTMGR is compressed" error message

Intro
This post tells you how to fix a compressed BOOTMGR file. This is for Windows Vista & Windows 7 only

What Happened
 
I was cleaning out my C drive, when I was done I only had 4 GB left, (better than 2 GB but still not that good) so I right clicked on my C drive then clicked properties and clicked the checkbox that said  “Compress this drive to save disk space”. So I clicked apply. It was going to take 4 hours so I cancelled it. Later on I needed to restart my computer, It shut down but when it turned back on it said “BOOTMGR is compressed press CTRL + ALT + DEL to restart”… Oh Dear!
  
The Fix

I got the cd that I used to install Windows and put it in the CD drive and turned on my computer. I pressed a key when it said “Press any key to boot from CD/DVD”. When it was done loading I clicked next.

  Then I clicked Repair Your Computer” and then clicked “Command Prompt”

In the command prompt window I typed “C:” and pressed enter.
Then “bootrec /FixMbr” and pressed enter.
Then “bootrec /FixBoot” and pressed enter.
Then “bootrec /rebuildBCD” and pressed enter.
I typed “exit” and pressed enter.

I clicked “Restart” and my computer booted just fine!
