My PC triple boot Windows 10, Ubuntu 15.10 and Kali 2016.1. It boots from Ubuntu Grub. Everything worked fine until yesterday. A couple of days ago, Kali released version 4.4 of the kernel and I installed it. Then I moved to Ubuntu and run update-grub to teach Grub that something changed. Then I retry to boot Kali did not boot anymore.

If I selected advanced options and run Kali with previous 4.3 kernel everything works as expected, but if I try to boot updated kernel the system freezes on purple screen and the light of the ssd keeps blinking on, so I'm forced to shutdown the system.

I tried reading /var/log/syslog, but it seems to write anything about latest kernel booting.

The PC has an Intel i7 6700k, 64bit architecture and Nvidia GeForce gtx980m. I installed Nvidia proprietary drivers to get Cuda working.

Is there anyone that knows a possible solution to this annoying issue?

Thanx in advance
