Ubuntu使用BIOS啟動時, GPT分區表下安裝grub2報錯 的解決辦法
報錯信息如下:
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.

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