Hey everyone! This question came from askubuntu.com (https://askubuntu.com/questions/948697/problems-with-external-ubuntu-installation) where we couldn't find the answer. I was advised by @sudodus to give it a try on this forum. So here I am! Here comes the problem:
I have a laptop (HP ProBook 470 G3) with a 256 GB internal SSD. It has Windows 10 installed on it. I also have a external (USB) Seagate Expansion drive, which is 1 TB.
Due to the limited size of my SSD, I'd like to install Ubuntu on the Seagate. To be precise: on a partition of the Seagate. (Because I have a NTFS partition with about 600 GB of data on it, and I don't want to loose that).
So I downloaded the Ubuntu 16.04.03 LTS ISO1 and made a bootable USB-stick with Rufus. Booted into the stick and goed trough the installation process. So far so good. I've created three additional partitions and made one of them the swap and the other two ext4. (Mount point / and /home). I also set the boot loader to install on the Seagate, which is sda. (My SSD is sdb). The installation finished and said to me that it was time to reboot. So I removed the USB-stick and rebooted.
But... It gave me the following:
error: unknown filesystem.
Entering rescue mode...
grub rescue> _
I have been troubleshooting for days and I'm really getting tired of this :(
Google told me that i have to reset the root and prefix in the GRUB rescue mode, but whatever I try, it keeps saying 'unknown filesystem'.
However, what did work was booting the USB-stick and hit escape (or C) to give me the GRUB terminal from the stick's GRUB. Setting the root and prefix there, followed by:
insmod normal
nornal
resulted in a proper boot. So yes, I am abled to boot into my Ubuntu, but this ofcourse isn't the way I want it to be. I've also done the thing above, followed by:
sudo grub-update
sudo grub-install /dev/sda
in the Ubuntu terminal, but rebooting, again, resulted in the GRUB rescue mode.
I also discovered that this might be GRUB legacy? Not sure if that's a problem.
So, what are your thoughts about this? I hope that I gave enough info, and I'm really looking forward on solving this issue.
Thanks in advance,
