Thanks to all replies... I got the cloning working. The recipe that finally worked was pretty similar to the "dd" provided but with some differences, because I couldn't get the MBR correctly working with other recipes, :(
Suppositions: 1.- New HD is bigger than old one, so that the free space left is enough to contain the partition you'd like to get bigger. 2.- The partition to get bigger is the higher one (most to the right). 3.- There's a gParted live CD available or something that would allow resizing root partition (of course it can't be mounted then). Recipe: 1.- Clone entire HD from old HD into new one (dd if=/dev/hda of=/dev/sda). This will end up generating the exact old HD structure, but for some reason the higher partition (most to the right) can't get resized to a bigger one (as if it was of a fixed size), although cfdisk shows the free space that could be used. 2.- Halt and swap HD's. This will work out of the box, :)... 3.- Generate a higher partition, at the right of the currently higher one. Hopefully it'll end up being bigger or at least the same size as the one intended to be expanded. Generate its FS (mke2fs -j -L "..." /dev/hda8) 4.- Clone the partition originally intended to be bigger into the new generated one (dd if=/dev/hda7 of=/dev/hda8). This will still show up weird things, like even though cfdisk will show some size for the new partition (in my case way bigger than originally intended partition to be expanded), "df -h" will say that the FS is exactly the same size as the originally copied. But that'll get overcome, :). 5.- Remove original partition just copied, which wasn't allowed to be extended. 6.- Reboot. At this point there's no problem with grub menu because hd8 became hda7 by removing the original partition, :). This is just to check everything went OK, and system could be rebooted, etc. 7.- Resize new generated partition. As this for me it was the root partition, I had to do it with a live CD, the gParted one. When using gParted, the weird thing about cloning the partition with dd still showed up. I saw a big partition, but mostly the size of the copied one showed up as used, which I knew was wrong... Any ways, expand the partition to the left (I didn't leave any free space to the right, so there was no room for expanding in that direction), meaning expanding from the header of the partition. At the end the partition is showed bigger, and with the right amount of data (which is less than the size of the copied partition even though at the beginning the used data was showed to be that big). 8.- Reboot the system, check with cfdisk, and "df -h /" for example, etc... I'm not sure why some things that were supposed to work as I was doing things before (like trying to clone the MBR without the partition table, etc) didn't work, but this just worked out...
