Zorin OS 16.2 not working

Zorin OS 16.2 once ripped onto the USB it doesn't show up on boot options

Laptop is Razer Blade 15 (Late 2020)

I'm not sure if the Razer Blade 15 has a key you can press to temporarily change the boot order without having to edit the BIOS.

If it doesn't, then press F1 or Del repeatedly as you power the machine on to enter the BIOS setup, go to the Boot tab and change the boot order so the Zorin OS USB stick is first in line.

According to a couple forums about the Razer Blade 15, the boot device needs to be formatted as GPT in order for the BIOS to pick it up as bootable.

How do I format it into GPT?

Plug the USB stick in.

If you don't already have gdisk:
sudo apt install gdisk

In Terminal, type:
sudo gdisk

That starts up a child process. Type ? to see the options available.

BE SURE YOU'VE CHOSEN THE USB STICK AS THE DRIVE YOU'RE WORKING ON.

We want to type the o option (create a new empty GUID partition table (GPT)), then confirm the action.

Then we want the w option (write table to disk and exit), then confirm the action.

You should see something like:

OK; writing new GUID partition table (GPT) to /dev/sdb1.
Warning: The kernel is still using the old partition table.
The new table will be used at the next reboot or after you run partprobe(8) or kpartx(8)
The operation has completed successfully.

Now we've got a GPT partition table on the drive. Now you'll have to reboot.

Once Zorin OS has booted, open terminal, and type:
sudo gdisk

The child process starts in Terminal. Now type p to print the partition table.

You'll see something like this:

Disk /dev/sdb1: 62330880 sectors, 29.7 GiB
Sector size (logical/physical): 512/512 bytes
Disk identifier (GUID): 168CC26E-54C1-4F9D-98F0-92227F45620B
Partition table holds up to 128 entries
Main partition table begins at sector 2 and ends at sector 33
First usable sector is 34, last usable sector is 62330846
Partitions will be aligned on 2048-sector boundaries
Total free space is 62330813 sectors (29.7 GiB)

Then type v to verify the disk. You should see "No problems found."

Now you can use the Disks application or any USB burning application to 'burn' the Zorin OS .ISO file to the USB stick.
