我最近做了一个LFS并对GRUB做了一些修改。我添加了 update-grub 命令。我可以设置背景颜色和突出显示颜色。但是当我添加自定义主题时-update-grub给出-
正在生成 grub 配置文件...
找到主题：/boot/grub/theme/dark_squares/theme.txt
找到 linux 映像：/boot/vmlinuz
找到 initrd 映像：/boot/initrd.img-no-kmods
完成
看起来不错。不是吗？
但是，当我重新启动时，一些错误闪过太快，但它可以正常启动。但是，我设法（不要问如何）读取错误 -
错误：
/boot/grub/fonts/unicode.pf2找不到文件。
错误：找不到合适的视频模式
这是我的/etc/default/grub-

答案1
就我而言，我尝试使用 GRUB 命令行（无grub.cfg文件）进行启动，因此我必须加载视频模块才能启动我的 TinyCore：
insmod all_video
如果没有这个，我会得到与OP相同的错误。
然而，作为阿尼科特·巴塔查里亚回答，我还必须手动复制unicode.pf2文件才能/boot/grub/fonts输出terminal_output gfxterm有效字符。
答案2
unicode.pf2通过将文件复制到/boot/grub/fonts.
