    installing Windows 8.1 in a external HDD from USB drive?


    Hi, everyone. I bought a new and faster drive (7200 RPM) for my laptop and put it in an external enclosure with USB 3.0 connection (my laptop has 2 USB 3.0 ports as well). I want to do a clean install of Windows 8.1 (Pro) into this drive. I'm thinking about to creating a Win 8.1 bootable USB drive using Rufus software, in UEFI mode (and GPT partition).

    I've been wondering: can you boot from this USB drive and install Windows into the external HDD? It's not that I'm lazy (not to much lol), but I need to perform some operations on the current HDD, and I don't want to swap the HDD just for installing Windows, because it takes some time to do that and I would have to swap it back anyway.

    And before you ask, I don't want to use a disk cloning/ghosting software as I really want a fresh install, as I'm facing some bizarre issues with Windows lately, those ones usually only solved via formatting the partition or performing a clean install. Thanks in advance.

    I know you can do that with the Enterprise Edition, but I don't believe you can do that with the Pro edition.

    Officially, the only way to do that is to create a Windows To Go drive from an already installed Windows 8.x Enterprise. Windows 8.x Pro does not have the Windows To Go option. The normal Windows Setup will not let you install to removable media.
    You could try this though, Windows 8 To Go - Setup on a USB Flash Drive or USB Disk
