Newest of Newb questions--won't boot from USB

I used unetbooti to put the iso on my usb drive, booted from usb drive in the bios, and...nothing. It says "No bootable drive'.

I read a ton of threads and all the faqs, but all the errors seem to at least have gotten past that step.

Any advice for what I might be doing wrong?

Thanks.

Okay, that seems to have computer recognizing the USB drive...

But now it's stuck on "ISOLINUX 4.02 DEBIAN-20101014 EHDD Copywright (c) 1994-2010 H. Peter Anvin et al"

Shouldn't it be doing something?

Most excellent. It appears to be installing now.

More stupid questions to follow as they emerge. Thanks.

Partitioning discs/selecting disc to partition:

It's showing two, the USB drive and the hard drive onto which I want to install OMV.

The hard drive is the one I want to partition, right? (I've disconnected the eventual RAID storage drives.)

I swear I read the tutorial and the wiki...it was just over my head.

I chose the HD, figuring the worst case was that I'd have to re-do something later.

It works! WOOT!

So now I really go newb.

And off to figure out how to set up the RAID array.

This is really cool.
