Could you help me?

Hi there!

Can you tell me if you're using an UEFI or a Legacy system? I need to know that in order to reproduce and fix this issue.

Thank you.

Use UEFI system

I tried reproducing your issue without success, check if your EFI was formatted as FAT32 nor you selected the correct partition.
