GParted delete partition clarification (screenshot)

Postby paulmo » 2017-04-17 13:53

After upgrading to new version, then deleting partition of previously-installed version and re-sizing new partition to take up unallocated space, my laptop started in grub rescue> mode, so I set path and loaded module by these instructions:
https://help.ubuntu.com/community/Grub2 ... escue.3E-1
Then I ran:
Code: Select all
sudo update-grub
sudo grub-install /dev/sda

and everything works fine. What is safe to delete now in GParted (screenshot), and how to safely expand /dev/sda4 to use unallocated space without borking my system again? Does grub-install mean that a boot loader is now in /dev/sda4 (and I can safely delete sda1)?

Neither Img tag around URL nor Upload attachment is working for me, so here's the screenshot URL:

Thanks for help.

If you are running in UEFI then you need to keep sda1 or you will not be able to boot the machine, if you have installed via legacy options then you can probably delete sda1 as grub should be in the MBR.

Thank you for responding to the 2nd part of my question: I am running in UEFI so I'll keep sda1.

As you are using gparted you can use that to expand your partition although you will have to do it from a live environment, just boot a live disc and then use gparted as normal, expanding sda4 it to fill the available space.

EDIT I can't see anything else to delete

ok thanks, do I delete unallocated partitions before expanding sda4? In my limited experience GParted is only available in live cd (in my case usb) mode anyway.

Unallocated space is free space available on your hdd, it's not a partition until it is created, all you need to do is expand your sda4 partition.

And if you want gparted after installation it can be easily installed in the usual manner synaptics/apt-get/aptitude/etc.
