Windows 10: Dual OS with one EFI

I have two operating system running, windows 10 pro and home. I have the windows 10 pro on ssd and windows 10 home on hdd. The problem is that the EFI is on the hhd. I clonned the windows 10 home from ssd to hdd. Then installed the windows 10 pro on ssd. How can i move the efi from hhd to ssd? In the picture, Disk 1 is SSD and Disk 2 is HDD

Hi,

The reason you are having problems is because you cannot dual-boot on a EFI / GPT system.

The system must be a LEGACY BIOS / MBR system as the EFI / GPT system has extra security to prevent the second OS being setup and used.

How I know is because I tried to do it too.

I hope that this helps you get your PC up and running as a dual-boot.

Kind regards,

Mark

 

Use MiniTool Partition Wizard to delete the 16MB MSR partition in front of D: drive in your screenshot (Disk 1). Use the resize partition option to move the front of the D: drive partition over so you get about 500 mb of free, unallocated space at the beginning of disk 1. Then pick up at step 2 here:

Before starting at step 2 above the user entered diskpart and selected disk 0. (In diskpart, drives start at 0, not at 1. You can use the list disk command in diskpart to see the drives.)

UPDATE

Just for you, I deleted my EFI system partition and recreated it . Here's where I started from:





I've got 120 MB unallocated space at the front of my SSD. C: drive is Windows 10 Pro. E: drive is Windows 10 Home.

I ran the following commands:
NOTE: Make sure in the disk part commands you are selecting the correct disks and partitions! Don't just go by my numbers. Especially when you are selecting the new system partition before assigning the drive letter - it might not be partition 3 on your system.

Note, my MSR is only 16mb in size because of my small SSD.

Rebooted the computer into UEFI setup, reset the boot order to boot from the new EFI partition (Windows Boot Manager in UEFI).

Thank you. *Smile But how about if i want to create an EFI for my windows pro?

 

You use the same procedure. Paying attention to the note I included:
NOTE: Make sure in the disk part commands you are selecting the correct disks and partitions! Don't just go by my numbers.

 

Question: Why are you running Windows 10 Pro and Home? Windows Pro is Windows Home with a couple of added features like Bitlocker encryption, networking tools and remote desktop capability.

 

When I assist others, I like to have the version of Windows that they might be using to be sure I am not telling them to do something not available on their version. I also have a hard drive with Windows 7 Home and Pro installed.

 

But how did you do this part?
x:\Windows\system32>bootrec /fixboot
The operation completed successfully.

x:\Windows\system32>bcdboot c:\Windows /s T: /f ALL
Boot files successfully created.

x:\Windows\system32>bcdboot e:\Windows /addlast
Boot files successfully created.

x:\Windows\system32>

 

I am newbie. did you start the command at boot? Can i remove the hdd before the operation? Thank you for helping, gladly appreciated.

 

You can do it with both drives installed. Use your EASEUS Partition Master program to delete the 16MB "other" partition at the front of Disk 1, the SSD. Then move the beginning of the Windows (C: drive) partition to the right a little bit so that you end up with about 120MB empty space at the front of the drive. Once you get the 120MB empty space at the front of the drive, then you can press Win+X keys to open a command list and select Command Prompt (Admin). In the Command Prompt (Admin) window is where you enter the rest of the commands listed.

 

What should I do if i get this message?
