"MBR 3FA:_" error when booting Win7 Partition on Debian

[InterestedInLinux]

I have configured a virtual machine in VirtualBox 4.1.18 (64-bit) to act as a pointer which will enable me to boot from a separate partition, Windows 7 (64-bit), as described in the article below:
geekery[dot]amhill[dot]net/2010/01/27/virtualbox-with-existing-windows-partition/

When booting up the Windows 7 partition, I am met with a text prompt on the command line which reads: "MBR 3FA:_". Nothing happens when I input any characters or press enter. Below is a screenshot of the issue:

I was not able to find any articles that solved this issue. Any help with this issue would be greatly appreciated.
