Ubuntu: Installation to external hard drive - not booting


I have the same problem as Why does my external hard drive not boot

I tried all suggested solutions on the web even I removed the internal hard drive and I let the installation use all the external hard drive size to install it but it still not able to boot.

If you installed Ubuntu by using the real installer, you just need to install GRUB on the internal drive. If you've used the USB-installer, you need to look in the BIOS.


Not all external HDD can be used to boot operative systems. This is a sad truth I had to uncover with my external 500GB Iomega HDD, that requires a power connection. If your external HDD also requires a separate power connection, then it probably won't work.

Another important thing is the interface it uses to communicate with the machine, it should be USB.

PS: I just saw images of your HDD! online, so unless I got the wrong pictures, I believe it should be able to boot an operative system. Looks like the BIOS theory is better.
