I accidentally deleted my swap partition via gparted.

(I'm still logged in the system so restoring should be easier) Can someone help me please? I'm not sure how to configure it because the Ubuntu installation did it automatically.

There are 3 partitions right now:

  /dev/sda1 -> Ubuntu installation root, mounted at '/'

  /dev/sda2 -> Windows partition

  /dev/sda3 -> Fedora partition

and /dev/sda4 if im not mistaken was the swap partition (4GB size)

Just use gparted again to create the additional /dev/sda4 partition, and format it as type "linux swap".


  • Here, I deleted the my /dev/sda6 swap partition in the highlighted space:

    enter image description here

  • Right-click on that unallocated space, and click on New; choose type "linux-swap", click on Add:

  • Apply changes

  • Right-click on the new swap partition and choose "swapon":

    enter image description here

  • Unless you removed it, the swap entry in /etc/fstab should still be there.

    • Check from the terminal with: grep swap.*sw /etc/fstab, and you should see a long line like:
    UUID=adc15cab-1cd4-4278-9a1d-59016cced6dd none swap sw  0  0
    • If you do not see such a line, obtain the UUID using sudo blkid | grep swap, and add a line in this format to /etc/fstab.

    • If you do see such a line, but the UUID does not match what was returned by blkid, then edit fstab to match. (Note: The line in fstab should not be commented out, i.e., it should not start with #.)

  • Run free -m to verify the swap partition is active.

  • I dont see the swap partition listed in fstab. The only sda* entry in fstab is sda1 (which is the root '/' ) Aug 26, 2012 at 18:29
