I have Sony Vaio Fit computer with a dual boot setup of Windows 8 and Ubuntu 14.10.
After upgrading to 15.04, booting into Linux fails with a number of '
builtin file not found' errors.
I tried toggling Secure Boot but that doesn't help.
The boot-repair info is at http://paste.ubuntu.com/12101145. If anybody has a suggestions, I would appreciate.
