I am running the following command to install GRUB:grub-install --target=i386-pc --recheck --debug /dev/sdaI get the following error:grub-install: warning: this GPT partition label contains no BIOS Boot Partition; embedding won't be possible.grub-install: warning: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are UNREL
I run the following commands to install grub in a CentOS 6.4 image I am creating manually:
chroot /mntPoint grub-install --just-copy
echo 'root (hd0,0)
install --stage2=/boot/grub/stage2 /grub/stage1 d (hd0) /grub/stage2 p (hd0,0)/grub/grub.conf'|\
chroot /mntPoint grub --batch --no-floppy --device-map=/boot/grub/device.map
Ordinarily these operations complete in just a few seconds.
Is it possible to use grub-install or update-grub to just search on specific disk/partition? (or ignore specific)?
I installed Ubuntu 12.04 on my hard drive, but i wished to do some testing on it without harming current installation, so I "rsynced" root partition (the only) to the USB partition (ext4). I did fix /etc/fstab on USB partition.
