A reboot is not a hindrance.
You can boot up Zorin LiveUSB, then tap the e key at the Grub menu to Edit Grub.
Find "quiet splash" on the screen and add the following parameters to it, so that it looks like (No Typos Allowed): "quiet splash i915.modeset=1 acpi_backlight=vendor acpi_osi="
Then exit the grub editor and proceed to boot normally.
If it works in that mode, then once installed, you can permanently edit grub
sudo nano /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.modeset=1 acpi_backlight=vendor acpi_osi="
ctrl+x to exit, the y key to say yes to save, then enter key to save as current configuration.
sudo update-grub
