Swift SF315-S2. Ubuntu Windows 10 dual boot - partition (size) not recognised

I am trying to install Ubuntu 18.04 LTS alongside Windows 10 on my acer Swift SF315-S2.

I first, on Windows, shrank the partition allocated for that operational system. In total I freed 292 Gb to install Ubuntu

When I tried to install Ubuntu, I got a message that I did not have enough space to install the OS (the message was "You need at least 8.6 GBs disk space to install Ubuntu. This computer has only 4.5 GB", which is not true, as I freed some 300 GB to install Ubuntu.

I read on a few forums and I think this could be related to the SATA mode. Default SATA mode for my laptop was RST with optane, whereas I read people saying that changing it to AHCI would solve the problem. That did not work for me. Windows was no longer booting and I could not install Ubuntu. So I managed to reset the SATA mode to the default value and my windows installation ins back to normal.

Has anyone out there faced the same issue with an Acer laptop? What was then the solution?

Fire up Disk Manager and show us a picture of the current partitioning setup, maybe that will suggest something.

Yes I run Ubuntu 18.04 LTS on my Acer Swift.

Before you change in BIOS the SATA flag from RST to AHCI, you need to disable Optane memory with the Optane tool and then reboot and change the BIOS flag, so both Windows and Linux will see Optane memory and the hard disk as 2 separate disks.

I imagine you wanna keep Windows and dual boot Linux and Windows. In that case I advice you to get to know a partition tool, either in Windows (disk mgmt or mini partition tool) or gparted in the live USB of Ubuntu. In the partition tool you can resize the windows partition to make room for a new partition to install Ubuntu.
Please read and prepare the installation notes of Ubuntu how to install Ubuntu alongside Windows. And as a precaution make a backup of Windows and a recovery USB of Windows.
