I can't see any explanation for this... you are doing the right thing.

Obvious question: you didn't have /dev/hda5 mounted while
copying/resizing?  (I think you'd have known about it if you were...)

Apart from that, it looks like Parted might be silently failing.
(It shouldn't!)

When you resize, does it show a progress meter?  Any funny behaviour?

Does that file exist?  (Can you open it via /boot/boot.b?)
