I am so confuzzled... boot1: /boot 6 in Clover Legacy

Hello!

I'm trying to run 10.13 on a Dell Inspiron 17R N7110, with an i5. When I boot from USB, I get this:

boot1: /boot

6

I tried to boot clover on a 1st gen i5 laptop that's otherwise identical to this 2nd gen one, and Clover will load just fine... Google has been absolutely no help.

Thanks in advance!
