I have a TOSHIBA A660 laptop have intel i5 450M and GPU geforce GT 330M, and I attempted to install Zorin OS 17 using a USB flash drive. I tried installing it using the safe mode. However, during the installation, an error kept appearing.
Can you get it to boot in live mode? If so, can you please install Synaptic Package Manager from Software (yes you can install apps in live mode, they just don't stick after install!),
then try this:
install the "xserver-xorg-video-intel" if it is unchecked.
Just to add Toshiba's are notorious when it comes to GNU/Linux!
Which graphics are you using?
You can double check using LiveUSB if needed:
sudo lshw -C video
It seems likely you need to boot from a different kernel.
This can be done by completing the instalaltion and upon reboot, immediately entering the Grub Menu, selecting Advanced Options for Zorin and selecting the (Recovery) kernel.
From there you can enable networking, then back up to the recovery menu and down to Root - Drop to Prompt.
Using that terminal, you can install a working kernel (We need to know your Graphics in order to suggest a kernel.)
Can you check if there's such special settings in BIOS related to graphics?
I have already installed Zorin 17 on too old mac mini, 2010 model, having only 256MB GPU GeForce 320M and indeed it works fine with kernel 6.5 using nvidia legacy PPA
