gnu grub minimal bash like problem 1.99 steam os.

[Plaguz]

So I tried installing steam OS on a blank harddrive. I think I did something wrong as I was working tired which is never a good idea.

anyway when I boot up the machine it just goes to this same screen. unless I reset the BIOs I can do back to the default MSI bios.

here is a video of my problem

my machine has no optical drive.
Windows has not been installed on the hard drive what so ever. I have no OS I just want steam os installed.
I do have a usb flash pen in the back of the machine which has steam os on it.

How do I get rid of this grub menu and restore the whole hard drive or just fix whats going wrong??
