我正在尝试正确配置 Ubuntu;令我头疼的问题之一是 rEFInd 启动菜单不再出现。当我检查启动顺序时,我发现 Boot0002 对我来说是未知的,这让我感到困惑。您对未来的发展有什么想法吗?
对 BOOT0002 有什么想法吗?谷歌搜索无结果!
我当前的问题是:没有声音,没有蓝牙,鼠标仅在 75% 的启动时工作,没有 rEFInd 启动菜单。
我的机器:(MBP 13“2016)我的操作系统:Ubuntu 20.04.1 LTS

我也遇到过同样的问题,refind 消失了。不幸的是,我不知道是什么原因导致你没有声音和蓝牙。
对于 refind,对我有用的方法是删除中文字符启动项,然后手动重新添加 refind 作为启动项。
您可以调整以下命令:
efibootmgr -v
#at this point, check the numbers of the boot entries.
sudo efibootmgr -b 0002 -B
#remove all of the Chinese character boot options. For you the boot number appears to be 0002.
sudo nautilus /boot/efi
#this helped me determine the file path for refind on my system. In my case it was /boot/efi/EFI/refind/refind_x64.efi
df -h
#view all of your system partitions. You need to determine which partition on your system corresponds to /boot/efi
sudo efibootmgr -c -d /dev/sda -p 1 -L refind -l /EFI/refind/refind_x64.efi
#you can type "man efibootmgr" for more information. You need to determine which partition on your system corresponds to /boot/efi and put the number of that partition after the -p option.
efibootmgr -v
#at this point, check the numbers of the boot entries. In my case refind was 0000 and ubuntu was 0001.
sudo efibootmgr -o 0000,0001
