Install an operating system on an external disk when laptop is running?
I was wondering if there is any way I can install an operating system on a USB hard drive while I have my laptop fully running. It seems to me like it would be a usefull thing to be able to do because then you could install an OS on a hard drive then take that hard drive and fully isntall it on a computer, instead of needing the whole computer there. Is this possible?
