I suppose everything in the partition currently is well within 2TB, as it
is fresh install. And as far I could see, best I could do was make some
directories show content, try as I could, I couldn't copy grub directory
so that I would be able to 'insmod normal'.
And wouldn't it also be against this theory, that post-install I am able
to copy the old grub directory to new location and be able to read
content of this new directory but not old?

Unfortunately my BIOS tells no such thing.

Thanks I'll do this when I can commit some time on this project again,
it is obviously not important to me to have huge flat partition, I'm just
curious as why it didn't work.
