无法访问 grub

我是新手，安装了 ubuntu 14.04 和 windows 7，但 grub 没有启动，直接进入 windows。
我启动了 live cd，在终端中输入了sudo fdisk -l以下内容

WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.

我能做些什么？

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1   *          63    15130079     7565008+   b  W95 FAT32

您可以使用boot-repair实用程序修复此问题。以 EFI 模式启动您的 Live CD，打开终端，然后按顺序输入以下三个命令：

sudo apt-add-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install boot-repair

然后，从 Unity Dash 启动 Boot Repair，它将解决您的问题（希望如此）。
