I want to download ubuntu for my win10 as a secondary OS for... reasons. Too long story.
I downloaded ubuntu 14.04 from disk I found from library. I had to use disk instead of internet download because poor connection. (it would take few days to download all)
First of all i had to use tools disk offered because computer did not open ubuntu in next restart.
Now each time my whole computer starts, it says something like Windows could not be started and do you want to see OS selection screen.
Beginning in windows selection begins windows normally, as I now write this post in it.
But start with ubuntu makes another ' Windows could not be started' screen. Strange. I can just begin with windows.
How can I launch pc with ubuntu in this case?
