Converting GPT to MBR without Booting into Windows: A Step-by-Step Guide for Kali Linux Installation alongside Windows 10 'gpt iso to mbr'

When installing multiple operating systems like Kali Linux and Windows 10 together, it's essential to understand the differences between GUID Partition Table (GPT) and Master Boot Record (MBR). GPT is a newer partitioning standard that supports larger hard drive sizes than MBR. However, when dual-booting older versions of Windows with Linux or other operating systems like KLI, you may need to convert your existing setup from GPT to MBR.

Below are the steps on how to do this:

Step 1: Prepare a USB Drive

To begin converting your hard drive's partition table without booting into an operating system (OS), first ensure that you have a USB drive handy. Connect it to your computer and then launch EaseUS Partition Master, which is free software available for download from its official website.

Step 2: Access the BIOS/UEFI Settings

After launching Easeus Partition Manager, navigate through the top menu bar until you see "WinPE Creator". Click on this option. Then click 'Next' to proceed with creating a Win PE environment USB drive that can be used for booting into your computer's Recovery mode.

Step 3: Create A Bootable USB Drive

Once the process is complete, safely eject the USB device from your system and then plug it back in again before powering down. Now restart your machine while holding down F2 keys simultaneously until you see a list of options appear on screen - select 'UEFI firmware settings' by pressing Enter key twice at once when prompted do so now since we want booting into UEFI mode instead normal legacy bios mode.

Step 4: Convert GPT to MBR Using EaseUS Partition Manager

After accessing the BIOS/BIETE setting, navigate through various menus until you find an option labeled as 'Boot Order' or something similar depending on your motherboard's manufacturer and model. In this menu, move USB drive up so that it becomes first in boot sequence followed by hard drives if they exist already present there.

Once done press F10 key to save changes then restart once again once prompted do not remove any external devices yet!

Step 5: Format the Target Partition as MBR

After successfully entering into EaseUS Partition Manager without having access to an operating system, you'll see all available partitions listed on your hard drive. Select the partition that contains Kali Linux and click 'MBR' at the top-right corner of this window.

Confirm by clicking yes when prompted whether you are sure about formatting data present within chosen area since once done there will be no turning back! After completion, you should see a message saying 'The disk needs to be initialized' - press Next button twice until finished.

Step 6: Install Kali Linux

Now that your target partition is formatted as MBR, it's time to install Kali Linux. Insert the installation media (USB stick or DVD) and reboot your computer while holding down Shift + F2 keys simultaneously during boot process if necessary depending on UEFI/BIOS settings.

Follow prompts until you reach 'Something Else' option during initial setup - select this choice then use mouse pointer to highlight free space at bottom left corner of window where we previously created MBR partition earlier today; click 'Continue' button once done. Then follow rest instructions provided by Kali installer software which should now automatically detect our newly formatted GPT drive as /dev/sdx1 (replace 'x' with actual letter assigned) ready for installation without any further intervention required from your side!

That's it! Your hard drive is now set up to dual-boot both Windows 10 and KLI alongside each other seamlessly. Remember always create backups before attempting such advanced operations though, just in case something goes awry during process...
