GRUB 오류 - 적합한 비디오 모드를 찾을 수 없습니다.

최근에 LFS를 만들고 GRUB를 일부 수정했습니다. update-grub 명령을 추가했습니다. 배경색과 하이라이트 색상을 설정할 수 있습니다. 하지만 맞춤 테마를 추가하면 -
update-grub제공 -

Grub 구성 파일 생성 중...
발견된 테마: /boot/grub/theme/dark_squares/theme.txt
발견된 Linux 이미지: /boot/vmlinuz
발견된 initrd 이미지: /boot/initrd.img-no-kmods
완료됨

좋아 보인다. 아니요?

그러나 재부팅하면 일부 오류가 너무 빨리 깜박이지만 정상적으로 부팅됩니다. 그러나 나는 오류를 읽는 데 성공했습니다(방법은 묻지 않음).

오류: /boot/grub/fonts/unicode.pf2파일을 찾을 수 없습니다.
오류: 적합한 비디오 모드를 찾을 수 없습니다.
