Did you had any Issues during the Installation?
Are Secure Boot and Fast Boot in the BIOS turned off?
Is Fast start-Up in windows turned off?
Did you installed Zorin with Nvidia Drivers or without?
Installation didn't give any errors at all.
Secure Boot is off, I don't see any 'fast boot' option in the bios.

Give up.
Ubuntu 24.04 LTS with Cinnamon works.
You could try it with installing without the Nvidia Drivers. These You can install after the Installation, too.
And as Tool for creating the USB Stick, you could try instead of Etcher Rufus. Because Your BIOS is UEFI, look in Rufus on ''Partition Sheme'' to use GPT.
Did You checked the Checksum of the ISO?
and when You install Zorin, what Installation Mode You have chosen? Install Zorin alongside Windows or Something else?
Oh, and beneath Secure Boot disabled, You should look if TPM is disabled, too.
