- Now i'm installing ubuntu 18.04 on an external usb.
- Cloned full ubuntu installation from usb to the second SSD.
- It's booting normally but to GNU GRUB screen .

grub> ls

hd0 (hd0,gpt1) (hd0,gpt2) (hd0,gpt3) (hd0,gpt4) hd1 (hd1,gpt1) (hd1,gpt2) (hd1,gpt3) (hd1,gpt4)

grub>boot

You need to load kernel first
