How to dual boot Ubuntu and Linux Mint
Dual boot Ubuntu and Linux Mint | Dual booting two GNU/Linux distros.
When someone mentions dual boot, often it’s referred to dual booting a GNU/Linux distro and Windows, or Windows and MAC OS X. In this post we will dual boot two Linux distributions and show you step by step how it’s done. This time we will show you how to dual boot Ubuntu and Linux Mint on a single drive. In this example, Ubuntu is pre-installed and we installed Linux Mint afterwards and setup the dual boot.
The process can be done vice versa since both systems are based on the same distributions and have the same installation. You can also check out tutorials how to dual boot these systems with Windows 10 following these links Dual boot Linux Mint and Windows 10, Dual boot Ubuntu and Windows 10.
Please note, before you proceed if you already use GNU/Linux as your daily driver on your PC, backup everything first.
Requirements for this process:
- Empty space on HDD
- Linux mint bootable USB
Underneath is also a video tutorial for this process:
Starting Linux Mint installation
Plug in your bootable Linux mint USB, restart the PC and boot the Live CD. Once the Live CD is booted up, start the installation.
First two screen will be prompts to setup your language and keyboard layout.
On this screen, installation will prompt you to install additional drivers, codecs etc. This is usually recommended step to do.
Formating partitions and dual boot setup
This is a very important screen. On this screen we need to choose how Linux Mint will install. The most easiest option is the first one. As we can see here, Linux Mint installation already detected that Ubuntu is pre-installed. This means that Linux Mint installation will prepare the OS and install Linux Mint alongside Ubuntu without harming and affecting installed Ubuntu and the files you have on it. That’s why we will choose the first option.
On this screen, we need to setup partitions and hard disk space. The process is here simple. In the first field we need to select drive on which we are installing Linux Mint. Since, this is situation where we have only one HDD, our only one drive will be selected. Bellow is a graphic representation of our Ubuntu OS and Linux Mint installation and how much space they have or will get after we finish setting up the partitions.
By default, the installation will divide hard disk space in 50:50 for each OS. In order to allocate more hard disk space to one OS, we just need to move mouse cursor in between the borders of our two OS installations, that border is a slider and we need to move it to one side.
After we finished setting the partitions, click continue and we will get a prompt with a pop up and it will ask us to confirm the changes.
User account setup
Next step is to setup the user account and and computer name.
After you setup the user account, the installation will start and it will take some time. Usually it takes around 15 minutes to finish but all that will depend of the HDD we have.
Once the installation is finished, we’ll get a prompt a again and it will ask to restart the PC. Remove the bootable USB and restart the PC.
As soon as the PC restarts, we need to have this screen. This is the GRUB bootloader. On this menu we choose which OS we want to boot.
So, if you get this screen, it means that you succeeded in setting up the dual boot and have installed the Linux Mint.
This was the process how to dual boot Ubuntu and Linux Mint. Thanks to installers of Linux and Ubuntu the process is nowadays simple to execute but still it’s important to mention again to watch out on which partition you’re installing which system and always have backup ready.
Thank you very much for your time…
I have dual boot ubuntu 16.04 and mint os installed on my laptop. I want to uninstall/remove mint os from my system and expand free space for ubuntu. Could you please suggest me the steps to be followed.
Hi there… To make this change, there are plenty prerequisites to do first and to check as well. First is of course, if you have data on Mint, backup the data in order to transfer them later on Ubuntu. The first important step is to check and determine where is the GRUB bootloader installed? Is it on a separate partition or is it with one of the OS-es? If it’s with Mint, then you’ll need to have it installed on Ubuntu. Once you figure out the GRUB situation, then you need to determine is Ubuntu installed with LVM – logic volume manager or not – you can check that with the steps from this forum thread. You have a different procedure when expanding a partitions which has LVM and when it doesn’t. Once this is determined, make sure the Ubuntu is primary OS for booting in the GRUB, then on Ubuntu you can simply just with Gparted wipe the Mint partitions(careful with this also). After that then you can with these methods expand the Ubuntu partitions – Method for the LVM and method without LVM.
Also, be careful and have everything backed up before doing this. I also suggest to allocate the new empty space to your home partition in order to have more free space for your files. You can expand root partition if needed but with this you need to be extremely careful and it can be risky. Take care and regards…
I have both Ubuntu & Linux Mint on my MacBook how do you get to grub boot loader?
Are both O/Ss able to share User folders (documents/pictures/etcetera) as well as run each others apps?
Please do not share/trade/sell my email address.
Hi Sharon… Thanks for commenting. Appreciate you took the time. To answer your question, just want to confirm it first so that I’ve understood it correctly and correct me if I’m wrong.
If I understood correctly, you’re asking – if you can make a setup on one machine, on one PC and maybe on one hard drive, run both Ubuntu and Mint, both OS/s to share the same user files and folders and share each other’s installed apps?
If this is what you’re asking, then I’m afraid the answer is no – at least on the app sharing part. User file sharing is possible but the setup can be bit tricky to set it up. This requires to have a separate hard disk partition or a separate hard drive, and have that mounted on both OS/s. Hope this answers your question. Thanks again for your time…
PS. Regarding the e-mail address concern. No need to concern about me sharing anything from you, I do not share any personal information. On this site I only try to share my knowledge and experience the best I can. In fact, I’ve deleted the email address from the site’s database. Also, no need for your to provide a real email address, you can leave a mock up/fake email address and I’ll still answer the question. It’s only left here as a requirement so it’s a bit easier to reduce/remove spam bots commenting. Best regards…
HI thanks for the tutorial
I already have Windows 10 and Ubuntu, I want to install Mint as a third OS.
I want to know if the steps in this case are the same?
Hi there… Thanks for commenting.
You can use the same steps, but be careful. By default, with these steps, the Mint installation will overwrite your currently installed GRUB boot loader. Depending of the setup you have, there’s always a chance that you can loose the ability to boot to other OS-es, which will lead then to troubleshooting and updating the GRUB. But by default, the Mint’s GRUB should pick the old GRUB’s configuration and just update it and have the other OS-es as well. Me personally would actually go with the steps of manually installing Mint(create a separate partition for Mint, install the Mint on the new partition without GRUB), then update the Ubuntu’s GRUB(this way it will still be able to detect and add Mint to the boot loader and be able to boot but not loose access to other two OS-es and if something happens, I can always delete the Mint partition and start over). Essentially, your mileage can vary. Research triple boot procedure’s before going with it… Best regards and have a nice weekend!
Thank you very much for your help
My boot loader is not finding Ubuntu 20x, but it was installed on good on hard disk; I installed after Mint 20x so that i could the disros
