Recommendations on cloning a bootable main disk

Thanks for the instructions on the BIOS - umm, nothing was wrong.  
Having the USB stick prior to entering the BIOS made the device show up.

OK, dd'd the disk.  Took a long time, 94 minutes, but everything is 
transferred, except for this email.

Next is to resize in gparted - which didn't complete.
I followed a youtube video at https://www.youtube.com/watch?v=cDgUwWkvuIY

Just to note,*sdc has never been mounted. *

The video is done in a virtual machine, but I followed the part showing 
how to do the resizing.  The linux-swap was turned off.  The error is as 
follows:

GParted 0.30.0 --enable-libparted-dmraid --enable-online-resize

Libparted 3.2

*Grow /dev/sdc2 from 29.99 GiB to 723.03 GiB*  00:00:00    ( ERROR )

/Unable to satisfy all constraints on the partition./

========================================

*Move /dev/sdc5 to the right and grow it from 29.99 GiB to 29.99 GiB*

========================================

*Move /dev/sdc2 to the right and shrink it from 723.03 GiB to 29.99 GiB*

========================================

*Grow /dev/sdc1 from 208.48 GiB to 901.52 GiB*

========================================

/dev/sdc1 is ext4 and what I want extended      208.48 GiB
/dev/sdc2 is the extended partition                   29.99 GiB
/dev/sdc5 is the linux swap which was turned off 29.99 GiB and was 
inside the extended partition
unallocated was                                                  693.04 GiB

Partitions were dragged and moved per the basic instructions.

Can you give me a hint what went wrong?  I'm kind of surprised that it 
failed, essentially in the first step, growing the extended partition 
after turning linux-swap off.

The problem might be that gparted still has a problem with leaving 1MiB 
at the end for the duplicate boot information.  I found a comment in 
2017 for gparted: http://gparted-forum.surf4.info/viewtopic.php?id=17646

And: https://bugzilla.gnome.org/show_bug.cgi?id=738144

Is there a practical work around to my reported error?

Thanks,
Bruce
