[SOLVED] This computer has only 0 bytes disc space remaining. (Linux Mint)

I'm trying to install linux mint 19.3 Cinnamon on my PC. I get this error message before I can proceed to partition management stage and then everything freezes so I reboot.

• CSM is disabled.
• Secure boot is enabled.
• Windows 10 is installed on my NVMe SSD.
• Flash drive is formatted as GPT UEFI using Rufus.
• My mobo is ASUS Z270F Gaming.
• I have two other SSDs which are left unallocated. One M.2 SSD and another SATA SSD working properly.

What should I do?

Boot to the live environment and run gparted, what does it show?
