我正在尝试在具有硬件 raid（raid 5 中的 3 个磁盘）的台式机上安装 Ubuntu 13.04。如果相关的话，我相信我有一个 ICH8 芯片组。
因此，我使用启动盘创建器创建了一个安装 USB 棒，其中包含 amd64 Ubuntu 桌面映像。我继续安装，选择清除所有内容并安装 Ubuntu（无 lvm、无加密或类似的东西）。安装似乎很顺利，直到最后，我收到一条错误消息，提示“无法安装 GRUB”
无法安装 GRUB
我认为它最初尝试了 /dev/sda，但随后我得到了一个菜单，我可以在菜单中选择一个网络分区。我尝试了其他选择，但似乎没有任何效果。我需要卸载某些东西来安装 GRUB 吗？
其他安装路径候选的屏幕截图：
引导加载程序安装失败
以下是输出ls -l /dev/mapper
ubuntu@ubuntu:~$ ls -l /dev/mapper
total 0
crw------- 1 root root 10, 236 Aug 25 06:48 control
brw-rw---- 1 root disk 252, 0 Aug 25 14:17 isw_bifaeaafcc_Volume0

brw-rw---- 1 root disk 252, 3 Aug 25 14:17 isw_bifaeaafcc_Volume0p5
ubuntu@ubuntu:~$
我最终选择了“继续不使用引导加载程序。”，希望能够弄清楚如何在安装后安装 GRUB。
有没有办法安装 GRUB，以便系统可以启动？如果您需要更多详细信息或系统规格，请告诉我。
编辑：这是故障期间 /var/log/syslog 的输出

答案1
这是一个假袭击控制器。除非您必须使用 Windows 双启动，否则最好避免使用它们，而坚持使用普通的旧式 Linux 软件 raid，您可以在 BIOS 实用程序中破坏伪 raid 阵列后使用备用安装程序进行设置。
如果您必须使用假 raid，为了进一步排除故障，您将需要检查 /var/log/syslog 以获取关于 grub-install 失败原因的更详细的错误消息。
