https://asus-linux.org/ seems to have some guides and tutorials.
Generally:
- Turn off Safe Boot and features that inhibit booting other operating systems and USB media in your BIOS.
- Get the installer running. Try the failsafe and fallback video mode options. Try different distributions next.
- Tackle one problem at a time. Google it. Add your hardware in question ("Asus Strix G15") and error message or exact issue ("black screen") to your query.
- Get the OS installed and then again do one thing at a time. Get it running first, maybe kernel options again help. Then the proprietary NVidia drivers, then the keyboard illumination and other less important stuff.
- If it's running somewhat alright and you're sure you're going to keep it, you can start moving your stuff there and installing applications.
You're somewhat likely to find answers to single issues by googling. Unless the hardware is really new, someone else has faced that issue before. For lots of manufacturers and common hardware, there are dedicated guides, wikis and forums. Try to find those and you might get a step-by-step instruction to get it running. Otherwise you have to isolate single problems by some means to be able to tackle them. This is difficult, especially if there are multiple issues at the same time. But that's why I recommend focusing on one problem at a time and googling it with the most specific query you can come up with.
I'm sorry that your hardware is so difficult to get running. The acpi=off could be a hint. But you have to figure out what exactly is causing the issue. Turning all ACPI off isn't something you want. Maybe you could try installing it this way and see if it's just the installer. Maybe the installed distro (after an update) does better. And choose a recent one with a recent kernel, in case the problem got solved in a recent kernel version.
