I have a lenovo thinkcentre m58 that has no hard drive. I have an iso image of windows 7 ultimate and I am trying to boot from an external hard drive. Since the desktop does not have a hard drive in it, I want to use the external as my main drive. The external drive will always be plugged into the desktop. Is this possible?

Check the BIOS to see if USB boot option is on. If not that, some devices just don't allow it.

Make sure to try a different USB port too.

@ThatVietGuy, I have a spare external hard drive that I wont be using so I wanted to give it a shot. It's not going to be my main computer, it's just a little project that I wanted to give a shot to see if it would work. I have tried formatting the hard drive and everything, but when I boot it up and say to boot from the usb drive, it says boot disk error.
