Hello all.
I've been trying to install to an external Hard drive for quite some time, and I finally had some success in that all the files for boot have made it to the external device. Unfortunatly, despite that fact that I went into advanced and made sure GRUB was to be installed on the external, it still failed anywayy and I get a Grub error 21 when I attempt to boot from USB ( go figure. )
So now I am back in the live CD trying to figure out how to fix grub.
This is what I tried:
ubuntu@ubuntu:~$ sudo -s
root@ubuntu:~# fdisk -l

root@ubuntu:~# grub-install /dev/sdb1
Probing devices to guess BIOS drives. This may take a long time.
Could not find device for /boot: Not found or not a block device.
*Sdb is my external device that I tried to install linux to.
So basically I can't install Grub to the Boot partition because it "can't find device for /boot:" ? So it recognizes that its a boot sector but at the same time thinks it is not ?
I'm stumped
Is there anything I can do to fix Grub that can be done from the Live CD ?
