I have a Sony VAIO T-Series (SVT15117CDS) laptop that came pre-installed with Windows 8. After having the computer for a while, I updated it to Windows 8.1. I now want to put Ubuntu 14.04 LTS onto the computer alongside Windows 8.1. I want to have an Ubuntu 14.04 LTS / Windows 8.1 dual-boot system.
When I try to install Ubuntu in UEFI Boot Mode I get the following error after staring at the Ubuntu loading screen for over a minute:
BusyBox v1.21.1 (Ubuntu 1:1.21.0-1ubuntu1) build-in shell (ash)
Enter 'help' for a list of built-in commands
(initramfs) Unable to find a medium containing a live file system
I am using UNetbootin to set up my USB key with the proper files.
I run into the same problem as above when I try it with Secure Boot enabled and disabled. When I try booting in Legacy Mode, I simply get a black screen saying "No operating system found".
The user in this forum topic seems to have the exact same issue as me: http://ubuntuforums.org/showthread.php?t=2108810 However, I was unable to make sense of how they resolved the problem.
The volumes on the disk are set up using the GPT partition style. Here is a screenshot of my disks:
Is there anything I can do to get Ubuntu working on this laptop?
Thanks!
