How do i move my Linux boot and root partition to an SSD while retaining my home partition on the HDD

Question

I already have Linux installed on my 1TB HDD to separate partition the boot, root, and home are on a different partition.

My system partitioning scheme:

I got a 256GB SSD and I want to move the other partition to it except for the home partition. How do I go about doing it?

Answer 1

• Boot from LiveCD (Ubuntu installation disk with Try without installing)
• Create the same partitions on SSD which you want to use using GParted except of /home.
• Create /mnt/sddboot and /mnt/hddboot folders
• Create /mnt/sddopt and /mnt/hddopt folders
• Create /mnt/sddroot and /mnt/hddroot folders
• Mount ssd partitions to your /mnt/ssdXXX mount points
• Mount hdd partitions to your /mnt/hddXXX mount points
• Copy everything from hdds to ssds saving ownership and timestamps: rsync -avz --progress /mnt/hddXXX /mnt/ssdXXX

• Edit /etc/fstab on SSD replacing UUIDs with /dev/sd?? devices for /, /home/, /boot, /opt partitions. For example:

  /dev/sdTT /       xfs     defaults   0    0
  /dev/sdXX /boot   ext4    defaults   0    0
  /dev/sdYY /home   btrfs   defaults   0    0
  /dev/sdZZ /opt    btrfs   defaults   0    0
  

• Make your ssd bootable in GParted

• Install grub on your ssd: grub-install /dev/sdX --skip-fs-probe --boot-directory=/mnt/ssdboot where sdX is your ssd device. It could be sda or sdb or sdc. You could see it in GParted.
• Switch bootable disk to ssd in bios and verify by booting from it
