Installing ubuntu 19.10 alongside zorin os 15

[jithtitan007]

Hi guys,
I was planning to create a dual boot in my existing zorin os 15 system with the new ubuntu 19.10.
But the problem is that out of the 1TB hdd space i allocated all the remaining space after swap and other things to zorin os root partition. But when i tried to install ubuntu it gives me the option to install ubuntu alongside zorin and even i can slide the disk space between the two. Will this work? Or is it something error in the part of ubuntu installation setup?
is there a way i can install ubuntu without uninstalling zorin os in such a parition?
Thanks

Hi, I haven't done dual booting before but from what I read it's important to resize partitions before installing another OS. Therefore I would think that if you have 1 TB of data and allocated most to Zorin, it is just a matter of reallocation to allocate free space for Ubuntu installation, so you aren't just trying to squeeze it in. I never used Zorin, so not sure if it has GParted, and if so you can re-allocate disc space. I recommend though first reading up on partitioning for dual boot. This article may help, and it also suggests using virtual box instead of dual booting. https://askubuntu.com/questions/164179/please-recommend-partition-sizes-for-my-dual-boot-configuration-1tb-big-ntfs-p

Post the output of sudo fdisk -l or an image of the drive from GParted so we know specifically what partitions you have, how many and where they are located on the drive.

This is the reponse of the code
sudo fdisk -l

Here is the gparted output.

The info in your first post indicating he Ubuntu installer suggests installing itself alongside Zorin should work. To have more control over it, you can use GParted which should be on the Ubuntu DVD/USB you are using. Open GParted and make sure the Zorin partition is not mounted. Then highlight /dev/sda3 in the main window and go to the Partition tab at the top of the GParted screen and select the option to Resize/Move and in the new window, set the size you want for the Zorin partition and the remaining space will be available as unallocated for you to use for Ubuntu. After the Resize selection, you need to click on Apply. Don't see that option in your image so if you don't have an Apply button there should be a check mark you can click. Mouse over the options at the top and it should show.

You should also read through the Ubuntu documentation at the site below. It talks specifically about dual booting UEFI with windows but the Introduction and General Principles sections give important information on dual booting UEFI. Since Zorin is UEFI, you need to make sure you install Ubuntu UEFI and that is explained at the link so read through the entire page.

Best to use Something Else where you either create partition(s) in advance or during install.
Then you can have a separate /home and maybe not use existing swap partition. Ubuntu will use existing swap also, but normal install now uses a swap file. If you click do not use on swap partition then it will still create a swap file.

If using multiple installs often better to have smaller / (root) partitions and separate data partition(s). Then you can mount data in every install. Best not to share /home as settings in one system may conflict with other system.

Be sure to boot installer in UEFI boot moe.
