ubuntu 14.04 安装后没有多重引导求助

[samuelgl]

以前在有 windows 的机器上安装 ubuntu 在其它的空闲分区后，默认都有 grub2 的启动选择。这次安装后没有出现菜单。想请教一下各位前辈大侠。暂时不知道需要提供哪些具体的信息给大家参考。见谅。谢谢。

开机直接进去windows？
是的话到引导区找win下引导ubuntu什么的
谁人唤吾名，循声不知处

Uefi enabled 或 Legacy Bios ?

Uefi enabled 或 Legacy Bios ?

主机板是支持 efi 的，不知道要怎么判断，谢谢。

开机直接进入 ubuntu 14.04 了。

[qy117121]

哦，这样的话sudo update-grub
看能不能搜索到windows，
能搜索到的话就重启看看有没有grub2菜单，
没搜索到的话，挂载windows系统所在分区在执行一次命令看看

主机板是支持 uefi
一般開機時可以設定 uefi / legacy Bios 選項
重點是問你
你的 Ubuntu 時 是在 uefi 還是 Legacy Bios 選擇下 安裝的

如果不確定 :

开机直接进入 ubuntu 14.04 了。

把下面指令 複製 貼進終端機 執行
1-1. sudo fdisk -l
1-2. sudo parted -l print
把結果直接複製 貼上來

[samuelgl]

硬盘分区是 mbr 格式
主板是 gigabyte H61M-DS2
原先的 windows 7 用了3个分区, 1个是隐藏的，1个是C盘，1个是D盘，
在安装ubuntu时，把数据合并了，清理出的扩展分区，在扩展分区里划分了若干逻辑分区装的
改天再把对应的信息贴上来，谢谢帮助

3. grub 分為兩代

主机板是支持 uefi
一般開機時可以設定 uefi / legacy Bios 選項
重點是問你
你的 Ubuntu 時 是在 uefi 還是 Legacy Bios 選擇下 安裝的

sudo parted -l print
Partition Table: msdos
1 1049kB 106MB 105MB primary ntfs boot

1. 你的 Ubuntu 時 是在 uefi 還是 Legacy Bios 選擇下 安裝的 ?
你還是沒給答案
2. 從你的 /dev/sda1 是 ntfs 猜測你是在 Legacy Bios 安裝 windows 以及 ubuntu
如果不確定 請繼續 3.
3. 登入 Ubuntu 桌面後
sudo mount -t ntfs /dev/sdb1 /mnt
sudo ls -alvRU /mnt
把結果 全部複製 貼上來

1 我真的不记得安装 ubuntu 时的选择了，不知道有没有记录可以查找？
3 是不是 应该 用 sudo mount -t ntfs /dev/sda1 /mnt
