I'm trying to clone Ubuntu 16.04 from USB stick (Sandisk 128GB installed with Ubuntu 16.04 - /sdc) to external SSD (brand new WD SN550 250GB - /sdd) on my Windows machine.
Following this tutorial, I made a Clonezilla USB then boot to it, connect my Ubuntu USB (Sandisk - /sdc) and external SSD (WD - /sdd), choose source and target as Sandisk and WD respectively, then finish the clone. Then remove Ubuntu USB (Sandisk) and Clonezilla USB, then reboot. Until now, my BIOS setup is EFI.
But when I reboot, my WD SSD doesn't show up when I press F12. Also there're something different running in the background during cloning. Here're some screenshots, saying the boot loader on /dev/xxx is not grub skip running grub-install
and some other strange stuff.
How do I fix it to boot to Ubuntu SSD? Should I have done something to the WD SSD prior of cloning?
