Windows and Linux Coexistence: Managing Dual Boot Systems with Windows on C: Drive and Linux on G: Drive

In today's digital world, it's common for users to work with multiple operating systems. One such scenario is running Windows as the primary operating system on the C: drive and Linux on a separate drive, say G:. This article provides a comprehensive guide on how to install and manage dual boot systems with Windows on C: and Linux on G:.

Preparation

Before you begin, ensure your system meets the minimum requirements for both Windows and Linux. You'll need a minimum of 20GB free space on the G: drive for a Linux distribution like Ubuntu.

Installing Linux

Create a Bootable USB: Download the Linux ISO file and use a tool like Rufus to create a bootable USB drive.
Boot from USB: Restart your computer and enter the BIOS settings. Change the boot order to prioritize the USB drive. Save and exit.
Install Linux: Boot from the USB drive, and you'll be presented with the Linux installation interface. Follow the prompts to install Linux on the G: drive, ensuring you don't overwrite your Windows partition.

Configuring GRUB

After installing Linux, you'll find GRUB, the Linux bootloader, installed on your MBR (Master Boot Record). By default, it should detect both Windows and Linux, allowing you to choose which operating system to boot at startup.

Adjusting Windows Boot Manager

Windows Boot Manager is responsible for starting Windows. By default, it doesn't recognize Linux, so you'll need to modify the Windows Boot Manager to include Linux.

Edit Boot Configuration Data (BCD): Open Command Prompt as an administrator and type bcdedit /create /d "Linux" /application osloader "EFI\ubuntu\shimx64.efi" /number 1. Replace ubuntu with your Linux distribution's name.
Create a Boot Entry: Type bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi. Again, replace ubuntu with your Linux distribution's name.
Reboot: Restart your computer, and you should see both Windows and Linux in the boot menu.

Troubleshooting

If you encounter issues, such as Windows not booting, you can repair the Windows Boot Manager using the Windows Recovery Environment (Windows RE).
