 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”

1	parted /dev/sdb set 1 bios_grub on

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

01 02 03 04 05 06 07 08 09 10 11 12 13

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.
