Vista bootmgr is compressed fix

Restart your computer and you should be good to go. If not, try the next solution.

Martin Bar Microsoft Agent. Everything was working well with a fresh install of Windows 7 except that if I had one of my external hard drives plugged into a USB, the computer tried to boot to it so I disabled all external hard drives in order to fix it but I had not re-enabled any of the drives yet including my cd drives as secondary boot options when I started getting the BOOTMNGR is Compressed message.
