uefi:windows10+ubuntu15进不去ubuntu

weiyc · **发表于 :** 2016-02-07 13:29

GNU GRUB version 2.0.2~beta2-20 ubuntu0.3
Minimal BASH-I like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device or file completios.
grub>

===============================================================
之前安装了ubuntu15，但一直只能进windows10，efibootmgr里面也没有UBUNTU，但今天开机突然出现了上面那个，感觉还有一线希望，请问该怎么操作才能进ubuntu和添加windows10启动项呢

宏基E5-573G ,UEFI ,secure boot:enable
(secure boot要设超级密码才能关闭，但设置密码好像会有问题。)

这是我的分区结构：
sda2（hd0,gpt2） esp分区
sda4（hd0,gpt4） windows
sdb2（hd1,gpt2） ubuntu /

感谢！！！

1. 使用 Ubuntu Live CD/DVD/USB 開機
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
把結果直接選取/複製貼上來

1. 如果 secure boot 是 enable
檢查看看有沒有這個檔案
\EFI\ubuntu\MokManager.efi

2. 由於種種原因
導致 secure boot 是 enable 要成功開機難度比較高
建議設定 secure boot 為 disable
然後把 \EFI\ubuntu\shimx64.efi
改為 \EFI\ubuntu\grubx64.efi

1. 這個 root hd1,gpt7 表示你的 / 掛載在 /dev/sdb7 uuid (43f89cff-0bb5-4eb3-94e4-1caa3810472f)

2. 但是上面的 /etc/fstab 顯示 / 掛載在 8c9c3544-9baa-4117-8b77-2c6416c7cfb4

3. 核對一下你的 uuid 跟 /dev/sdnx 的對應關係

不是的，按f12只有windows boot manger所以只能進入windows系統，沒有其它入口能讓我進入Ubuntu

一開始安裝完ubuntu時，啟動器寫入了/dev/sda2 安裝過程是正常的但重啟後就直接進入了windows10,沒有任何選擇的餘地。那個時候secure boot是disable的。

前幾天突然冒出grub>命令行，剛設置了超級密碼然後關掉secure boot後開機就沒有grub>直接進入windows了，現在再打開secure boot還是直接進入windows了。

不是的，按f12只有windows boot manger所以只能進入windows系統，沒有其它入口能讓我進入Ubuntu

1. 所以你希望按 f12 除了 windows boot manger 還可以有 Ubuntu 選項讓你直接進入 Ubuntu 不需經過 Windows ?

引用:

一開始安裝完ubuntu時，啟動器寫入了/dev/sda2

2. 如果你寫入分割區就還需借助別的開機載入程式例如 EasyBCD 或 Grub ... 等等開機載入程式來引導向 /dev/sda2 才能進入 Ubuntu
2-1. 你可以選擇寫入 /dev/sda 或 /dev/sdb (先寫入該硬盤前端 MBR 0 ~ 511 bytes) 就可以達到
按 f12 除了 windows boot manger 還可以有 Ubuntu 選項讓你直接進入 Ubuntu 的目標
如果寫進 /dev/sda 的 MBR 通常會覆蓋 Windows 的開機引導程式影響到 Windows 開機
所以建議選擇寫進 /dev/sdb (的 MBR) 不要選擇任何分割區 /dev/sdnx
2-2. 如果你原來安裝 Ubuntu 是成功的
不需重新安裝 Ubuntu
2-2-1. 可以使用同一版本的 Ubuntu Live USB/DVD 重新安裝 Grub 2 到 /dev/sdb 即可
2-2-2. 參閱
http://apexu.com/apexu/tw/modules/publi ... ?itemid=47
使用 ubuntuliveUSB 重新安裝 grub2 (UEFI enabled)
2-2-2-1. 注意

代码:

2. sudo parted -l # 確定你安裝 Ubuntu 時 掛載 / 目錄 的分割區 是 /dev/sdan, a 代表硬碟碼, n 代表分割區順序碼

2-2-2-2. 需要修正的地方

代码:

3. sudo mount /dev/sdan /mnt
3-1. sudo mount /dev/sday /mnt/boot/efi
10. apt-get install --reinstall grub-efi-amd64 # 注意 不加 sudo
10-1. efibootmgr -c --disk /dev/sda --part y

修正為

代码:

3. sudo mount /dev/sdb2 /mnt
3-1. sudo mount /dev/sda2 /mnt/boot/efi
增加
3-2. sudo mount /dev/sdb3 /mnt/home
10. apt-get install --reinstall grub-efi-amd64-signed # 注意 不加 sudo
10-1. efibootmgr -c --disk /dev/sda --part 2

2-2-2. 重新開機以前先檢查
sudo efibootmgr -v
確認按下 F12 有你剛剛增加的 Ubuntu 開機選項
2-2-2-1. 如果成功了請再貼文看看如何刪除多餘不用的開機選項
2-2-2-2. 如果還不成功
2-2-2-2-1. sudo efibootmgr -v
2-2-2-2-2. sudo cat /mnt/EFI/ubuntu/grub.cfg
2-2-2-2-3. sudo cat /mnt/boot/grub/grub.cfg | grep root
貼上來

3. sudo mount /dev/sdb7 /mnt

請問這裡的sdb7是筆誤嗎，因為/是掛載在sdb2上的。

1. 對

代码:

3. sudo mount /dev/sdb2 /mnt

1-1. 另外增加

代码:

3-2. sudo mount /dev/sdb3 /mnt/home

重開機不要按 F12
讓它自動開機
看看會不會從 Linux 開機
