ubuntu16.04开机出现grub>,显示error:failure reading sector 0xe0 from 'hd1'和error:failure reading sector 0x0 from 'hd1'，set root和set prefix后能进入引导，但重启后还是grub,我的是gpt分区.

1. https://help.ubuntu.com/community/Grub2 ... ng#grub.3E

2. https://help.ubuntu.com/community/Grub2 ... #grub.3E-1

3. uefi 開機 還是 legacy bios 開機 ?

uefi

使用 Ubuntu Live CD/DVD/USB 開機
1. 登入 試用桌面 把下面指令 複製 貼進終端機 執行
1-1. sudo efibootmgr -v
1-2. sudo parted -l print
1-3. 把結果全部直接 選取/複製/貼上來
不要摘錄 以免遺漏重要訊息
不要擷圖 方便回文直接引用你貼上來的資料 方便你閱讀
1-4. 請說明 安裝時 把 / 掛載在哪個分割區

我直接进入现在的系统操作可以吗，因为我在grub设置了root和prefix后可以进入系统

在/boot/grub找不到normal.mod,/boot/grub/i386-pc里面的不能用

1. 當然可以 (應該說 更好)
2. 如果可以进入现在的系统操作 請增加執行下述指令 (請使用複製/貼上 以免打錯字)
2-1. sudo cat /etc/fstab
2-2. sudo ls -al /dev/disk/by-uuid/*
2-3. sudo ls -al /dev/disk/by-partuuid/*
2-4. sudo cat /boot/efi/EFI/ubuntu/grub.cfg
2-5. sudo cat /boot/grub/grub.cfg | grep menuentry

1. 安裝時
沒有分割一個 esp 分割 FAT32 格式 掛載 /boot/efi
1-1. 參見
