This question might be a repeat of several other questions. But I have tried most of the solutions and beaten my head to understand the remaining. To no avail, however.
So I basically have two partitions, which I created using Windows's disk management utility. Partition C: has Windows on it. And Partition E: had nothing.
So I decided to install Ubuntu on it. I wanted to try Ubuntu out and see whether it was faster than Windows and better to use. I downloaded the latest Ubuntu 14.04 and booted it from the pen drive. On the installation options there was no option of "Install Ubuntu alongside Windows 7". So I went to "Something else" and selected the Partition E: and installed Ubuntu on it. Here's what happened afterwards.
When restarting, the computer did no detect the presence of Ubuntu at all. It directly started Windows, without giving me an option to select between the OS. And while in Windows, it did not show the other drive on which Ubuntu was installed.
So I thought, that maybe bootloader of Ubuntu hasn't been installed. So if I re-install Ubuntu, it might detect the presence of an already installed Ubuntu and then maybe I can do automatic installation instead of "Something Else" and install Ubuntu with the bootloader and swap.
I did that and the program did detect Ubuntu and gave me two options: "Erase Disk and install Ubuntu", "Install Ubuntu alongside Ubuntu" and "Erase Ubuntu and Install Ubuntu". I chose the last one.
Now, bootloader only shows Ubuntu. There is no mention of Windows. And moreover, if I select Ubuntu, nothing really happens. The screen turns purple and stays like that. I can only run the test version of Ubuntu from the pendrive. I don't know what to do now.
Is there a reliable, easy way to use both Windows and Ubuntu? I'm an Ubuntu noob --- so I am really struggling with it all.
Earlier I had just one partition with Windows on it. When I used the pendrive to install Ubuntu, it never detected the presence of Windows at all. I really want to give Ubuntu a shot, but at this moment I can't take the risk of not having Windows on my PC. So it's either Ubuntu+Windows or no Ubuntu at all!
