本文介绍了解决在Ubuntu系统中，使用BIOS启动时，GPT分区表下安装grub2遇到的报错问题。通过创建一个2MB的BIOS引导分区并设置其标志为“bios_grub”，成功解决了grub-install的错误，实现了跨磁盘安装。此方法适用于从BIOS设置硬盘为第一启动设备的情况。

Ubuntu使用BIOS启动时, GPT分区表下安装grub2报错的解决办法

报错信息如下:

root@fwhlin:/mnt# grub-install /dev/sdb
Installing for i386-pc platform.
grub-install: warning: this GPT partition label contains no BIOS Boot Partition; embedding won't be possible.
grub-install: error: embedding is not possible, but this is required for cross-disk install.
root@fwhlin:/mnt#

This is fixed by creating a 2 MB partition on the 2 TB hard disk and setting its flag to “bios_grub”

parted /dev/sdb set 1 bios_grub on

Here “1” is the partition number for the 2 MB partition.

root@fwhlin:~# parted /dev/sdb set 1 bios_grub on
Information: You may need to update /etc/fstab.                           
 
root@fwhlin:~# parted /dev/sdb print
Model: ATA WDC WD20EZRX-00D (scsi)
Disk /dev/sdb: 2000GB
Sector size (logical/physical): 512B/4096B
Partition Table: gpt
 
Number  Start   End     Size    File system  Name  Flags
 1      17.4kB  3049kB  3032kB  ext4               bios_grub
 
root@fwhlin:~# 

Now grub-install worked properly.

root@fwhlin:~# grub-install /dev/sdb
Installing for i386-pc platform.
Installation finished. No error reported.
root@fwhlin:~# 

I set /dev/sdb as first boot device in BIOS and it booted perfectly.
