When installing Ubuntu on 2 TB HDD i got following error.
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.
