This question already has an answer here:
I have been using Windows and ubuntu alongside each other for quite some time. Till Windows 7, things were fine. I installed Ubuntu inside Windows and all was fine. At startup, I would be asked if I want to boot Windows 7 or Ubuntu and I could choose.
However, starting from Windows 8, I could still install Ubuntu inside Windows 8 but while starting up, Windows 8 boots up automatically and in the end I am asked if I wanted to boot Ubuntu. Then if I choose Ubuntu, the machine restarts again and Ubuntu is booted. This is very annoying. If I want to use Ubuntu, I have to boot the device twice.
I have tried reinstalling many times, with different version of Ubunutu, it is always the same. Is there any work around this to make it like Windows 7? Or do you suggest some other method of installing Ubuntu alongside Windows 8?
