5 Things to do before dual booting Linux with Windows

1. Disable Secure Boot :

This is the most important step you have to do if you are planning to dual boot Linux with Windows — Disable Secure Boot.

Secure Boot helps to make sure that your PC boots using only firmware that is trusted by the manufacturer which usually only supports OS Microsoft Windows 8.1 and higher. And you have to disable Secure Boot to run some  PC graphics cards, hardware, or operating systems such as Linux or previous version of Windows.

So how to disable Secure Boot ? — All you have to do is to open the PC BIOS menu (access this menu by pressing a key during the bootup sequence, such as F1, F2, F12, or Esc — different for different manufactures) and find the Secure Boot setting and set it to Disabled.

If you using Windows 8.1 or Windows 10, then you can disable Secure Boot without entering BIOS. You just have to hold the Shift key while selecting Restart. Go to Troubleshoot > Advanced Options: UEFI Firmware Settings and choose disable option for Secure Boot settings.

**NOTE : In some cases, you may need to change other settings in the firmware, such as enabling a Compatibility Support Module (CSM) to disable Secure Boot. To use a CSM, you may also need to reformat the hard drive using the Master Boot Record (MBR) format, and then reinstall Windows.

2. Disable Fast Startup :

Majority of users forget to disable Fast Boot or Fast Startup before dual booting Linux with Windows — which results system to boot into Windows after Linux insatallation without showing the GRUB menu. Fast Startup is a setting that helps your PC start up faster after shutdown and by default it is enabled in Windows.

How to disable Fast Startup ? —  Unlike Secure Boot you don’t have to enter in BIOS to disable Fast Startup you can do it by going into Power Options in Control Panel like as follows :

  • Open Control Panel change view by “Large icons/Small icons”
  • Click Power Options.
  • Click Choose what the power buttons do.
  • Click Change settings that are currently unavailable.
  • Scroll down to Shutdown settings and uncheck Turn on fast startup.
  • Click Save changes.

3. Create New Partition for Linux :

This is not important but it would be better if you create a separate partition for Linux before installing. Yes I know you can create it during installation process but if you accidentally messes up with wrong partition during installation process may wipe your hard disk. So always createa new partition before dual booting Linux with Windows.

4. Install Windows first :

Sure you can install Linux and Windows in any order but highly recommend that you should install Windows first because setting up the Windows boot loader to load Linux is a challenging task. Because after installation Windows completely overwrites any boot loader that is already there, so if you have Linux installed already you can no longer boot Linux without playing around for hours or reinstalling Grub from a boot CD.

So it would be better and less complicated if you install Linux after Windows because most of the popular Linux distros automatically add Windows installation to its GRUB loader so that you can choose either Linux or Windows during system startup.

5. Live Boot then Install :

An interesting unique feature of popular Linux distributions is that you can try them without being installed.  So if you are new to Linux then you could be confused to choose your first Linux distro — that time just create bootable USB of your Linux distro and live boot it.Live booting helps you to lookup the features of that Linux distro.

Once you installed a Linux distribution along with Windows and you didn’t liked its features — it will be a royal pain in the butt to uninstall that Linux without messing Windows Master Boot Record (MBR). So always live boot to choose right Linux distro for you.
