I'm attempting a fresh install of Ubuntu 15.10 on a new Lattitude E7250 laptop off of a USB stick.
The process goes well and copies all the files to the hard drive and then asks me to restart to continue the process. When I click okay the following error appears before the laptop reboots: "error the master control interrupt lied" and am assuming the full text is: log error: “[drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!”
after reboot one of two things happen. If I leave in the usb drive the installation process recommences from zero and if I remove the USB then I receive a message: "no Boot device is found"
When running a live session I can see the ubuntu folders installed on my laptops' hard drive.
I've tried to boot both in Legacy and UEFI and have disabled fast-boot without changes
I'm not using any external monitors.
any suggestions about what might be causing this and how to complete a successful install would be much appreciated.
Regards,
Daniel

Just had the same and found a possible solution by luck.
If you switch to another console, eg CTRL+ALT+F3, you can log on. Try to delete (or move) the xorg.conf file. You can find the file under /etc/X11
Mine started the graphical user interface almost immediately after I deleted that file.
Hope this helps.
