[SOLVED] Invalid magic number when creating a mint 19.2 USB boot

I was using Linux Mint Cinnamon 17 installed as a dual boot along with Windows 10.
I decided to get rid of Windows all together since I don't use it anymore and I need to allow more memory to Cinnamon who sends me a warning for having low space available.
I created a USB boot with Cinnamon 19.2 and I was hoping to install it and change the memory allocation.
The boot sees the USB key and asks if I want to start with Cinnamon 19.2, but as soon as I hit enter I get :

- error: invalid magic number
- error: you need to load the kernel first

If I use my previous USB key (with Cinnamon 17) it works fine.

What am I doing wrong?

Thanks,
Frederic

When googling this error, most articles I found indicate that either your Live USB creation process went wrong, or your USB drive is unreliable. Try another drive.

Sorry for responding late.
I tried a different port, same thing, then I recreated the USB key using a different key (larger size as a matter of fact...) and BINGO! It works.
Thanks for your suggestion which made me think of using a different key.
Cheers,
