I want to make a new SSD Card my boot drive: Is there a good program on Ubuntu for that?

  • 772

So, I'm planning to get an SSD card soon and make it my boot drive, as I've heard that can make your computer boot much faster. I also want to try to leave my old HDD in as a secondary storage drive. Is there a good program someone can recommend to me to transfer the boot data onto the SDD?

Edit: I want to try to keep my current install of Ubuntu and just move it over to the new SSD card.

  1. Use the Raspberry Pi ssd creation tool. It has never failed me yet.

    1. make the same partition table on SSD like your HDD (user GParted or similar on GUI oder fdisk on console)

    2. boot from a live cd with old HDD and new SSD connected to your system

    3. mount the new SSD and old HDD (check the devices before with "sudo fdisk -l")

      sudo mkdir /mnt/new
sudo mount /dev/sdb1 /mnt/new

sudo mkdir /mnt/old
sudo mount -o ro /dev/sda1 /mnt/old

    4. sync you data with rsync from old to new

      sudo rsync --stats --progress --numeric-ids -axAhHSP  /mnt/old/ /mnt/new

    5. search the new UUIDs for your new partitions on your SSD with

      sudo blkid

    6. edit /etc/fstab on your new SSD with the UUIDs for "/" and "SWAP"

    7. chroot your new SSD

      sudo mount /dev/sda1 /mnt
sudo mount -o bind /dev /mnt/dev
sudo mount -o bind /sys /mnt/sys
sudo mount -t proc /proc /mnt/proc 
sudo mount -t vfat /dev/sda2 /mnt/boot/efi 
sudo chroot /mnt

    8. update grub (please check that /dev/sda is your SSD! or change the device name!)

      update-grub2
grub-install /dev/sda 

      update-grub

    9. finish, you can exit and reboot with your old system on your new SSD

    After this, you can mount your old HDD wherever you want in /etc/fstab
