My laptop always turns itself off when installing zorin os, the installation is not finished and suddenly it turns itself off. Yes, I have followed all the instructions in the installation guide such as disabling secure boot and fast boot and creating bootable using balenaEtcher. fyi My laptop doesn't have an OS yet.
I see you're installing with networking - I normally don't suggest doing that as it may break the system before booting the first time lol happens to me every time I install with networking enabled; doesn't matter what distro.
Also, how much RAM do you have; and what make / model is the laptop?
Test your hard drive. Bad sectors of blocks can create an i/o error that can shut everything down during an installation, too.
Check temperatures. Overheating during the installation process can cause a shutdown. You may need to clean the notebook computer vents, check thermal paste or place notebook computer on a cooling tray.
Do you know if (or rather, have you made sure that) you have the latest UEFI/BIOS and firmwares available for the motherboard and peripherals in your pc?
The software upgrades I neglected to flash initially was a serious cause of different problems for me, not just with Zorin but with different installations as well.
