I have recently installed Ubuntu 14.04 entirely on the HDD of my Dell Inspiron 14z which has 500GB HDD + 32 GB SSD. I have 24GB of SSD lying unused and I would like to allocate about 18GB of the SSD to Ubuntu. Please tell me what is an efficient method for doing it and what specific directories(such as home, tmp or boot ) can I move onto the SSD and what can be kept on HDD.


In your place I would make it like this:

  1. Install the system on the SSD,
  2. Keep the /home mounted on the HDD

The fstab's relevant rows would look something like this:

/dev/sda1       /         ext4     noatime,nodiratime,errors=remount-ro 0       1 
/dev/sdb1       /home     ext4     noatime,nodiratime,defaults          0       2
  • Would that be possible (although perhaps not recommended) without a reinstall? Copying over the whole directory tree (without /home), then changing fstab and rebooting? – Jos Apr 29 '14 at 9:59
  • Well, I have done something similar when moving from a smaller HDD to a bigger using: dd if=/dev/sda of=/dev/sdb. It took some time. After that I've booted from a live CD, I've resized the partitions with gparted, chrooted to the HDD, issued sudo update-grub2, and rebooted to the fitted new disk. – Frantique Apr 29 '14 at 10:40
  • @Frantique I am new to dealing with partitions can u plz give a more detailed explanation as to what I can do. I am ready to reinstall considering that I installed Ubuntu only today. Can you even tell me what all should i shift and corresponding commands (inconvenience regretted) – 9shank4 Apr 29 '14 at 10:44
