Is it possible to boot a windows Operating System from an external USB Hard Drive?
Yes it is possible, you will need to install in on the usb hard drive but there is a few problems. First you need to set your bios to check usb hard drives before your computer’s hard drive. However even then there is another problem. USB’s transfer rates is 3 to 6 times slower then the sata cables inside the computer. It is suggested anyone using an external hard drive for an external operating should use external sata connections, otherwise there will be lag because of the slower transfer rates.
