Keyboard not recognized during boot

Hello,

I recently purchased a used Mid 2010, 27" iMac. It didn't have a hard drive, so I installed a new drive. I'm trying to get into the Internet Recovery, but my USB keyboard doesn't get recognized until the folder with the question mark shows up.

Any help would be great!
