Without the USB drive connected, shouldn't your grub be booting hd0? - 
not hd1?

Try editing the grub line to boot /dev/hd0 instead.

In my opinion, I most definitely would have disconnected the internal 
drive before doing all this to make sure nothing could get written to it.

I know this does not help now.

Ed.
