I have Ubuntu 18.04 LTS installed on a 1000 GB HDD
/dev/sda (93% free space) on my laptop:
/dev/sda1 -> 512M - vfat - EFI System Partition /dev/sda2 -> 732M - ext4 - Linux File System ( /dev/sda3 -> 930.3G - crypto_LUKS - Linux File System (empty)
I would like to use a 120 GB SSD (not yet installed) for the OS on this laptop now. The old HDD should be simply used as an additional partition for file storage afterwards; no dual boot required. Instead of having to re-install Ubuntu again on the SSD, I am looking for a way to clone my existing system installation from HDD to the new SSD.
What would be the best way to achieve this?
