Hello, so i tried installing EndeavourOS on my new device, but installer screamed at me that efi partition should have at least 300MB. Im kinda scared to go further with installation. Should I just ignore the message and install it regardless or will it fail. More in attached images.
It shouldn’t fail as long as your EFI partition isn’t close to full already. That is just a warning.
You can check the available size e.g. with commands
du -hd 1 /boot/efi
Efi files are rather small.
