Installing Ubuntu
Step 7: Preparation for installing Windows 10
So after installing macOS High Sierra and completing post installation, the next step is install Windows 10. Before you install Windows 10, you’ll need to create a free partition. To create a free partition, follow the steps below.
@Gbilato has written a great guide about using Disk Utility on Mac. You can follow How to Use Disk Utility on Mac
But to make it moreeasy and avoi confusion, i'll explain the required process.
Go to Utilities and open Disk Utility.
Now select your Drive, not the partition.
Click on partition button and then click on + (plus) button.
Under Name you can type any name but for instance we’ll be using Windows 10.
Under Format select Mac OS Extended (Journaled).
Under Size you can choose according to your Hard Drive and workload on Ubuntu. But as stated above, we’ll be using 160 Gigs each for Ubuntu and macOS High Sierra.
Click on Apply button and then click on partition button.
Click on Continue.
Now it will create a free partition for Ubuntu.
When done, close Disk Utility.
The created partition will appear on your Desktop.
Now restart your PC.
Step 8: Installing Ubuntu
While restarting your PC, plug your Ubuntu Flash Drive.
Press F12 to enter your Boot Menu.
Select your USB Flash Drive with the UEFI Prefix.
Select Install Ubuntu and press enter key
When at welcome screen, select your language and click on Continue
Select Install third party software for Graphics and Wi-Fi hardware, MP3 and other media and click on Continue
When at Installation type, select Something else and click on Continue
Select free space, this is the space which we created using Windows Installation Drive in the third part of this guide
Now assign the space for the Ubuntu installation
Note :
Do not assign the whole space as you need to also assign space for swap area

Select Use as : Ext4 journaling file system
Under Mount Point select / and click on OK
Select free space 10000 MB and click on + button
Under use as select Swap area and click on OK
Select /dev/sdb5 ext4 /
