Although Microsoft wants you to trust Windows, a Linux operating system and a Windows operating system can coexist on the same PC. This article will guide you how to run a Ubuntu system and a Windows operating system in parallel.
You must consider two scenarios and decide which one is suitable for you. The installation sequence must be considered here. Installing Windows after you have installed the Ubuntu operating system is a problem, because Microsoft does not seem to care much about other friends.
If you have installed Ubuntu after Windows, it will be much simpler and almost no work or preparation is required.
Let's start to solve more difficult problems. If you already have a Ubuntu system and want to install Windows, you will lose GRUB, which is the default boot program. Windows does not care about it and erased it.
If you have already made this mistake, but you have not rewritten the Linux partition, don't be frustrated. The data is still there. What you need is a startup live CD containing Ubuntu (latest to 13.10. You need to install an application named Boot-Repair and use PPA to install it.
Remember, if you use a USB flash drive, it will be quite simple to install the application, because the Ubuntu installation image is a hybrid image. Start a Ubuntu session with Live CD, open the terminal, and enter the following commands:
sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get updatesudo apt-get install -y boot-repair && (boot-repair &)
Open the application, click "Recommended Repair", and wait. After this step is completed, restart the machine and you will see GRUB again to achieve dual startup.
On the other hand, if you have installed Windows and want to install Ubuntu, it will be easier. Start Ubuntu installation, select a non-Windows partition, format it as EXT4, select the boot program location, and then complete it.
If you choose to install the boot program on the same hard disk as Windows, it will erase Microsoft boot program. This is fine, because GRUB will recognize the WIndows operating system and you will not lose it. If you install it elsewhere, such as on another hard disk, when you choose to start from a different hard disk, you will see two of them.
