I installed Ubuntu 15.04 on a Seagate expansion drive. I tried booting it up from my machine, but it hangs (and I waited over 30 mins, just to be sure).
I tried using the drive from an Intel based PC, and it worked like a charm.
I then tried loading up the drivers using this guide.
I am stuck at step 3.1.6, which says to run
sudo amdconfig --adapter=all --initial.
This did not work from the USB installer.
How do I resolve this issue?
I tried using bootrepair, and the information it gave me is available here.
Here is a screenshot of the GRUB2 configuration and boot line (click here for a new window link of this for full size so you can clearly see what's there):
I tried adding nomodeset to the grub2 screen in the the line containing Linux instead of quiet splash in recovery mode and upstart mode. I have tried replacing the $linux_gfx_mode with nomodeset.
In the recovery scenario, I see the message Loading initial ramdisk, where it then hangs. I have tried installing it on my internal hard drive as well,the results are no different. I have also updated my BIOS to this,however the problem persists.
I can chroot into the installation using this,here I tried to install the amd graphics drivers but it was unable to find them.
Is it nessecary to:
- reinstall Ubuntu 15.04
- install an older version of Ubuntu
- fix GRUB
Or is there something else that I should do?
