如何在使用 rEFIt 安装 Lion 后恢复 Ubuntu

Question

今天早上升级到 Lion，大部分都很顺利，但是当我尝试重新启动到 Ubuntu（我在 Linux 上完成大部分工作）时，我只能进入 grub 命令模式。

我花了一大段时间来学习 Windows 机器上类似问题的指南，从 Ubuntu 安装盘启动并重新安装 grub，但我仍然无法启动到我的 Linux 分区。

我最终得到了一个非常简单易行的解决方案，但导致了一些数据丢失。

在多次尝试从 livecd 重新安装失败后，我放弃了 grub，只能重新格式化分区并重新安装 ubuntu，并注意到启动安装程序后在当前副本上重新安装 11.04 的选项。

I re-installed, and must have gotten a new copy of grub set up correctly during this step. Only side effect was most of my applications I had installed through the softwarecenter were missing, but when I re-installed them settings were still there.

After 20 or 30 minutes of re-installing applications rEFIt and both OS installs are working the same way they were before the Lion install.
