I've used GTP instead of MBR, is it a problem?

You mean GPT. As I said, many modern laptops will work with either. Try it and see.

Are you using UEFI or legacy? If UEFI, are you certain your laptop has UEFI?

Are you certain you chose the correct options within the Clover installer for legacy?
Which options did you choose?

Are you using your BIOS boot menu to boot directly to the USB?
