这几乎与更新后，我应该为“GRUB 安装设备”选择什么？- 或者可能不是，因此询问，因为我正在通过 Vagrant 在 Virtualbox 机器上运行 Ubuntu。
我无法更新软件包，因此我运行sudo apt-get update了sudo apt-get dist-upgrade。它显示以下消息：
The GRUB boot loader was previously installed to a disk that is no longer present, or whose unique identifier has changed for some reason. It is │
│ important to make sure that the installed GRUB core image stays in sync with GRUB modules and grub.cfg. Please check again to make sure that GRUB is │
│ written to the appropriate boot devices. │
│ │
│ If you're unsure which drive is designated as boot drive by your BIOS, it is often a good idea to install GRUB to all of them. │
│ │
│ Note: it is possible to install GRUB to partition boot records as well, and some appropriate partitions are offered here. However, this forces GRUB to │
│ use the blocklist mechanism, which makes it less reliable, and therefore is not recommended. │
│ │
│ GRUB install devices: │
│ │
│ [ ] /dev/sda (85899 MB; VBOX_HARDDISK) │
│ [ ] - /dev/sda1 (254 MB; /boot) │
│ [ ] /dev/dm-0 (84833 MB; precise64-root)
我猜第一个选项是正确的，就像另一个问题的答案一样，但我不喜欢猜测！ 我将非常感谢任何帮助或见解。

假设您没有使用 UEFI，而我看不出您应该使用的原因。此外，假设您最初没有以某种花哨的方式进行设置，那么是的，第一个选项是正确的。通过选择 /dev/sda，它将安装到 /dev/sda 的 MBR，BIOS 应该能够引导它。
