I somehow installed a MBR to my external hard drive and now it's conflicting with my main hard drive and OS. If I start up with the external hard drive on it hangs after the splash. If I start up without it turned on I blue screen and restart. How can I get rid of the MBR on my external hard drive?

If you follow sandmanwn instructions, you may be able to boot into Windows and you may be able to copy the files and re-partition the drive after Windows is loaded.
I am concerned about the boot drive changing partition type.
