how to remove other linux os and stay with ubuntu only

Question

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 ?

Solution

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

First restore Ubuntu's grub to MBR. help.ubuntu.com/community/Grub2/… Then you should be able to just use gparted from live installer to remove & resize partitions.

Wow! It could be this straight forward... I was racking my mind for no reason... Glad I stumbled upon this. Updating grub config file wasn't a good solution, had a figure it the hard way!.
