New FreeBSD User | HP Doesn't Boot

[Michael Starr]

Hello Everyone,

   I am a brand new FreeBSD user with minimal Unix knowledge. I have
"successfully" installed FreeBSD on a computer dedicated to the operating
system. However, after rebooting, the machine can't boot, nor get into BIOS.
I installed the system from a bootable USB stick. I would try another fresh
install, but currently I can't do anything. Could someone please direct me
to a solution? I hope I did not irrevocably alter my BIOS. Any help would be
deeply appreciated. Thank you.

Computer: HP dvr6 2150us (laptop)
