This is important step-2 for you. If you choose Automatically configure partition based on your available disk it will create three partition and one major partition (/root, /boot & /swap). In this scenario /home partition is not separated one and it was comes under /root partition. Its not recommended one and highly RISK. So i would advise you to create the partition manually by following the below steps.
Choose Second radio button I will configure partitioning. Then hit Done which is in topmost left.
Choose the partition Scheme, Then hit Done which is in topmost left.
See the Default mount point size which was assigned by system itself and there is no /home mount point. It seem’s /root mount point took remaining spaces.
Resizing /root mount point. Here I’m going resize the root mount point from 28.15GB to 15GB. Choose the root mount point and enter your new described size, then hit Update Settings.
Adding /home mount point. Click the plus (+) button which is showing in leftmost bottom and it will pop-up new window like below. Choose mount point name and capacity (values should be “disk space GB”), then hit Add mount point button to mount it.
New mount point added, then hit Done button which is in topmost left.
Accept the summary of changes that’s it.
