When you need to dual boot Windows with Ubuntu system along with this popular Linux distribution, you can set it up as given below.

Dual Boot Windows 10 and Ubuntu 18

There are tons of ways that you could set Ubuntu 18.04/18.10 partitions. Things would be a lot easier if you have already read our Linux Mint installation guide.

If so, this Windows 10 dual boot with Linux partition style would have a familiar ring to it. Similar to the Linux Mint installation partition guide, you need to set up two crucial parameters. Namely, Root mount point ( /)and Swap.  Additionally, if you plan on storing more files, adding a home (/home) partition is highly recommended.

The Root partition is kind of like the Windows OS folder where all your installed software and crucial ubuntu OS files will be stored. So the size of the Root partition is completely dependant on your usage. We are giving the recommended for reference. For Root partition:

Linux Mint 19 Tara Root Partition

  • Size: 15 GB to 20 GB (Recommended)
  • Type for the new partition: Primary
  • Location for the new partition: Beginning of the space
  • Use as: Ext4 Journaling file system
  • Mount point: /

For Swap partition :

Linux Mint 19 Tara Swap Partition

  • Size: Same as (or higher than) your current RAM size
  • Type for the new partition: Primary
  • Location for the new partition: Beginning of the space
  • Use as: Swap area

The Home partition is a lot like your other storage volumes of your hard drive in Windows 10. The main objective here is to have all your media files and documents in a separate partition other than the operating system files. Moreover, this can protect your files in case of an upgrade going wrong or corrupt system files. Its recommended settings are mentioned below:

Linux Mint 19 Tara Home Partition

  • Size: Remaining space or depending on your usage.
  • Type for the new partition: Primary
  • Location for the new partition: Beginning of the space
  • Use as: Ext4 Journaling file system
  • Mount point: /

So let’s set the ball rolling but before you do, make sure that the bootloader location is set to install to the main hard drive. And again, remember that the changes made are irreversible. So always make sure that everything is the way it should be before clicking Continue.
