External HDD as a Windows Boot drive

[LLamaGames]

I have a 2tb seagate hard drive and Im trying to use it as a normal HDD and install windows 10 on it until I can get a new HDD. Im using this method https://www.easeus.com/partition-master/install-windows-10-on-external-hard-drive.html and Im have trouble with the command Dism /apply-image /imagefile=D:\install.wim /index:1 /ApplyDir:F:\ My seagate drive is under the Letter F and my main SSD is under C. Im trying to apply the image to my seagate drive but I keep getting Either Error 2 or 3. Any Suggestions?

I wouldn't brother, having windows on USB 3/2 connection is going to be painful experience. I would consider linux more as it doesn't require as much disk write/read as windows and plus I have many servers running off a USB without any issues for many years.

The thing is this computer is for my girlfriend and it is only gonna be temporary until i can get a HDD or SSD. I have never used linux and it's gonna be playing some low end games as well

Windows on external is awful. 

Better wait for a new purchase of hdd/ssd. 

Or you can dismantle that external drive and put it inside your gf's pc.
