On my PC it only takes less than 20 minutes, but I’ve read that some users wait an hour to do it. This is a very easy to do… Only choose the ISO sourse, the destination disk, and configure the system partitions. USB 2.0 is not recomended (slower). A USB 3.0 driveis the best technology for this end (mutch faster). Here, we’re actually installing Windows on a USB drive so we can run it from a drive on any computer you want, and take it with you for troubleshooting, remote work, and so on.
Note that this is different from installing Windows from a USB drive, which allows you to install Windows on a computer that doesn’t have a CD drive (for that, please check this post). Here’s how to install a portable version of Windows 8.1 (or other versions, like Windows XP or 7) on a USB hard drive that you can take anywhere. You ever wanted a Windows to run on a USB hard drive or flash drive, to use on any computer you want? It’s possible :-D.
