    现在的引导程序是grub2，试一试
    install——修复/重装grub2
    代码:
    grub2-install /dev/sda
    update-grub2

    又觉得可能是device和后面这个对象不对？

    deepin@deepin:~/桌面$ sudo mount /dev/sda7 /mnt
    deepin@deepin:~/桌面$  sudo mount --bind /dev /mnt/dev
    deepin@deepin:~/桌面$ sudo chroot /mnt
    root@deepin:/# grub2-install /dev/sda
    未找到 'grub2-install' 命令，您要输入的是否是：
    命令 'grub-install' 来自于包 'grub2-common' (main)
    命令 'grub-install' 来自于包 'grub' (main)
    命令 'grub-install' 来自于包 'lupin-support' (main)
    grub2-install：未找到命令

    啊啊啊啊啊~~~~我也受打击了，不过我又看到一点
    挂载proc（重要，没有这一步将无法修复grub2）网上说的。
    代码:
    sudo mount --bind /proc /mnt/proc
    要不再试试？~
    到device看看，到底有没有这个设备，坑啊（sda？sdb？……）。
    把原系统的各分区重新挂载到mnt之后，再把dev和proc也挂载到mnt~

    果然，加了proc就可以了，但又出现了

    btrfs文件格式不支持？

    grub2对btrfs的支持不是很好，最好/boot单独分。我不知道你的btrfs及其子卷有没有启用压缩、raid或multi device。
    grub2安装时候会/proc/mount来探测文件系统。所以不挂载/proc就会出错。
