Is there a way I can boot into windows 7 from the external hard drive?

Q: I cloned my Windows 7 system from my internal hard disk drive onto a Western Digital USB external hdd.

Basically I am wanting the option to boot into windows from that external hard drive. I noticed in disk management that the boot file was not created onto the clone hard drive. I then tried to reinstall windows onto the external drive but windows 7 prevents installation onto a USB external hdd. Is there a way I can boot into windows 7 from the external hard drive only?
