That’s definitely a frustrating situation you have, and I very much encourage you to take the path that feels most possible to you!
Before moving on, I would like to point to trying what u/mvirts suggested, disabling ACPI from the grub bootloader. It’s easy and great for getting an installer running and working, and sometimes the freshly installed and updated OS whisks the problem away.
But regardless of what you choose, I wish you much luck in your endeavours!
