使用 CD 而不是 USB 在 HP xw4600 工作站上安装了 Ubuntu。但安装后它无法从硬盘启动。安装过程中显示：
The entire disk will be used: /dev/mapper/isw_digjcabegb_Volume0(ext4) 250.1GB
Running “grub-install /dev/mapper”…
Error pop-up:
Unable to install GRUB in /dev/mapper
Executing ‘grub-install /dev/mapper’ failed.
This is a fatal error.
然后又出现另一个错误：
Sorry, an error occurred and it was not possible to install the bootloader at the specified location.
How would you like to proceed?
Choose a different device to install the bootloader on:
/dev/mapper
/dev/mapper/isw_digjcabegb_Volume0我从下拉菜单中选择，它又给我一个错误，说它再次失败，这是一个致命错误。然后它说安装完成，我需要重新启动计算机。
