  • When and by what is the message issued? I'll take a guess and say when updating the system...? There is probably not enough space on the boot partition to hold another Kernel. From the amount of used space I assume there are currently three Kernels installed. You can always remove old Kernels if you do not experience bugs with the current. Could you post the output of 'ls -alh /boot' – Nephente Sep 8 '15 at 15:59
  • I think you have to select /dev/sda2 then point your mouse on the yellow rectangle and drag to increase the space of the partition, but first you have to move upwards the unallocated (713.86MB) in place of dev/sda3 – Bento Sep 8 '15 at 16:02

  • Better not remove any. The Kernel 3.16.0 is the official one from the Ubuntu repository. You should probably keep this. The 4.1.6 was installed by you from some other source. Having two functioning kernels available is a good thing! That way you can still boot the system if your custom kernel should fail. Best to go with Pilot6's instructions and resize the boot partition after all. Keep in mind though, that although probably everything is going to go well, you should have a recent backup at hand. – Nephente Sep 8 '15 at 16:35

You need to boot from Ubuntu LiveUSB first.

Your sda5, sda6 and sda7 partitions are inside the extended sda4 partition.

You will need to extend sda4, then move sda5 and sda6 left, then extend sda7.

You will also need to re-install grub, because start sector of your /boot partition will change. It can be done from LiveUSB by

sudo mount /dev/sda5 /mnt
sudo mount /dev/sda7 /mnt/boot
sudo chroot /mnt
sudo grub-install /dev/sda
exit

  • doest it effect windows if i install grub in /dev/sda – Rishin Ravi Sep 8 '15 at 16:04
  • It is already on /dev/sda. You just need to update it. – Pilot6 Sep 8 '15 at 16:06
  • what is mnt @Pilot6 – Rishin Ravi Sep 8 '15 at 16:13
  • /mnt is a directory where you will temporarily mount your partitions to do the grub update. – Pilot6 Sep 8 '15 at 16:14
  • i am stuck sudo grub-install /dev/sda sudo: unable to resolve host mint grub-probe: error: cannot find a device for /boot (is /dev mounted?). Installing for i386-pc platform. grub-install.real: error: cannot find a device for /boot/grub (is /dev mounted? – Rishin Ravi Sep 9 '15 at 10:58
