I have Ubuntu 14.04 installed on my machine on a partition. I wanted to install Windows 10, so I installed it to another partition using a USB. Later there was the issue where I could not select the OS as it was always going to Windows 10. So I installed the boot-repair on a live Ubuntu and did the repairs. Now during boot it shows both OSs as expected.
But when I login to Windows 10, and after using for about 3-5 minutes, the machine crashes and restarts.
Any idea on how to find the issue?
