Using Clonezila to transfer ubuntu 16.04 for NUC

The basic reference is here and here.
The important thing for nuc is:

1. Choose the right version of clonezila,I test alternative stable - 20191024-eoan version,and it will crash in the middle. stable - 2.6.4-10(amd64) works for me.
   
2. Choose the right CPU architecture. [Important] For I use NUC-i7BEH6 and ubuntu,the hints in the second below picture is very important, I have tried the i686-version and cannot boot for the uefi reason. amd64 is fine.
   
   
3. After restore the image,often a Image authorization fail. System can not boot to this device due to security violation error will show up. Follow this turn off the Secure Boot will solve the problem. Or if it’s already turn off, then do the on-off-on operation.
