I'm using windows with homestead and I'm trying to enter vagrant up on the command line but I'm getting this error:

I searched online but all I could find was someone else asking the same question but no answer. What does this error mean? I went to the folder in particular and indeed there is no file called id_rsa. Can anyone shine some light on how to rectify this?
It looks like you need to generate an SSH key? You can do that by entering the command ssh-keygen -t rsa -C "your_email@example.com" (with your own email obviously) if you're using Git Bash.
When it prompts you for where to save the key just hit enter. Passphrase is also optional, just hit enter twice for a blank passphrase.
