i did try a chroot into the external drive per someone else instructions.

yes, it is the same on the smaller drive. basically everything was set
as it was on the previous drive.

but if it were installed on the copy from drive, shouldn't it then
also be installed on the copy to drive? all the config files were
there.

oddly enough it does. i was poking around in the BIOS this morning and
the usb is indeed a boot option. not what i wanted, but it is there.
i have successfully gotten the new larger drive to boot and load up my
old debian configurations.
since i could not get grub-install to work, even with chrooting in, i
ended up installing minimal debian on the empty larger drive
[installed in the system].
after setting the partitions there and having the installer setup grub
i shut the system down and swaped out the drives.
with the larger drive as external i cp -arv all the folders except
/proc onto the larger externally connected drive.
