Ubuntu: how to remove other linux os and stay with ubuntu only


I have latest ubuntu 15.4. I wanted to try fedora so I installed it afterwards and got dual boot. Now I want to remove fedora and stay with only ubuntu.

  1. How do I completely remove fedora and retrieve the space I gave it ?

  2. How do I remove grub ?

please write in details. I saw How do I delete Fedora 15 from Ubuntu 12? Fedora was installed first but it has little details and I counldn't manage to do that.

update: I tryed what kyodake suggested and still don't understand how to merge the 2 partitions. Bellow is the current status in my gparted: (I want to merge sda4 (deleted fedora) to sda1 (my ubuntu)). How do I mount it exactly ? enter image description here


Try this:

In a Ubuntu session, open a terminal,

Press Ctrl+Alt+T

Run it:

sudo -i  apt-get update  apt-get install --reinstall grub-pc grub-pc-bin grub2-common grub-common  grub-mkconfig -o /boot/grub/grub.cfg  grub-install --root-directory=/mnt /dev/sda  grub-install --recheck /dev/sda  fdisk -l  

By fdisk identify the Fedora partitions, are suppose /dev/sda7 and /dev/sda8, continue running:

umount /dev/sda7  umount /dev/sda8  gparted  

In gparted, select the hard disk, delete Fedora partitions y and to create a new, file system ext4, You can mount wherever you want in /media, /mnt, /home/user/.

Close gparted and run:

sudo update-grub  


  1. Put Ubuntu's GRUB in charge.
    From Ubuntu, run sudo grub-install /dev/sdX, ...whatever X is in your case. If there is only one HDD, it's usually /dev/sda. To figure out what X is for sure, run lsblk.

  2. Unmount, and delete the partition with Fedora, using the preinstalled Disks utility.
