OK, that helps, thanks. Could you test attached patch?
From: Andrei Borzenkov <[email protected]> Subject: [PATCH] efidisk: map EFI_NO_MEDIA to GRUB_ERR_OUT_OF_RANGE This prevents errors from diskfilter for removable devices during device scan. Write case is added for consistency. If read/write from removable is explicitly requested, we still return an error and text string is more clear for user than generic error.
