Why two partition deleted while I chose one (fdisk)?

  • 772

I selected one partition to delete in fdisk but as you see the 3rd partition which is swap is deleted too, why?

Device     Boot    Start      End  Sectors Size Id Type
/dev/sda1  *        2048 12584959 12582912   6G 83 Linux
/dev/sda2       12587006 20969471  8382466   4G  5 Extended
/dev/sda5       12587008 20969471  8382464   4G 82 Linux swap / Solaris

Command (m for help): d

  1. That is because /dev/sda5 is your only logical partition inside /dev/sda2, which is a extended partition. So by removing your extended partition, your logical partition will be removed as well.

    /dev/sda2 was an extended partition and /dev/sda5 was a logical partition residing inside of it. You can see that the Start and End positions of /dev/sda5 overlap with /dev/sda2.

    If this is not what you intended, you can still quit fdisk without applying changes by using the q command.
