How to install Windows 10 on external HDD

Hello,

I have an external HDD. I want to install Windows 10 Enterprise which I have purchased recently.

Please guide me, if possible step by step on how to install Windows 10 on external HDD.

Thanks,

Hi,

Usually, this problem occur due to software incompatibility or corrupted USB drivers. For us to better assist you, we would like to clarify the following:

• Have you made any recent changes on your computer prior to the issue?
• Which driver did you uninstall? Have you reinstall the driver? If yes, how did you reinstall the driver?
• Have you check if the external HDD is visible in Device Manager?

If the issue still persists after uninstalling some games, we suggest that you run the troubleshooter for hardware and devices. If you're using the latest Windows 10 version, follow these steps on how to run the Hardware and Devices troubleshooter:

• Click the Start button and select the Settings
  icon.
• Choose Update & Security from the list.
• Click Troubleshoot in the left pane of the window.
• Under Find and fix other problems, select Hardware and Devices and click
  Run the troubleshooter.

We're looking forward to your reply.

 

trying to install 7 w/o optical drive or USB drive (do have an external hdd)

This method is going to be trial/error on my part but here's my stab at it:

Use the guide he linked. Substitute in step 4, DO NOT FORMAT. Pre-format the hard drive with another PC/current windows install in NTFS format, then create 2 partitions. 1 to install from and one to install to. So in step 4 I beleive all you would have to do is a "clean" "select partition XX" & "active" command.

In step 5, use virtual CD/DVD software.

EDIT:

The only problem I see with above is how are you going to install while booting? Meaning, for it to boot wouldn't you have to be external but yet must install to an internal drive?
