The OP can tell us Hopefully, they made an Image / Clone of their OS drive before they started making adjustments but t doesn't look like they did that.However, on current SSD I messed a lot with partitioning, and want to make some adjustments during cloning.
Which means the Nuclear Option is the fastest, easiest, cleanest way.
And also from MiniTool:
Well, I'm not reinstall system from scratch, because it consumes to much time and effort to configuring everything again.
EFI/ESD partition is on SATA drive, because it used to be a system drive, but now system sits on an older 2 TB M2 drive.
I want to get rid of 500 GB Disk 0 from computer and clone Disk 1 to a new, wider M2 (4TB), but without volume D:.
And asking you if it is possible:
a) to copy EFI/ESD to new drive and also cloning Disk 1 into the same drive, in a way causing Windows to boot and operate normaly
OR
b) to clone Disk 1 (or at least volume C:) to new drive, but with 200 - 500 MB free space before, for recreating EFI manually with bcdedit and bcdboot.
My considerations are from fact, that currently C: sits after 16 MB of MSRP partition, almost on beginning of the drive and I don't know if it safe to move system partition on GPT drisk in another place counting from the beginning of the drive.
I prefer to start from scratch with the new drive. Let's say the new drive is disk 2.
diskpart
select disk 2
clean
convert gpt
select part 1
del part override (these two commands will delete an MSR partition if it was created by the convert gpt command)
create part EFI size=100
format fs=fat32 quick
assign letter=s
create part MSR size=16
exit
Then on the previous Windows installation, run "reagentc /disable"
Then copy the previous Windows installation to the space after the MSR partition on the new disk (I like to use Macrium Reflect Free for that).
Assign the newly copied partition drive letter T:
then "bcdboot T:\Windows /s S: /f UEFI"
Boot from the new disk. Once into Windows booted from the new disk then "reagentc /enable"
Nice clean disk layout with everything fresh and new, except the old Windows system has been transferred over.
The UEFI - GPT drive has the partitions layout like below.
This is what I would do. The results are the same as Navy.
- Do a clean install on the new drive as UEFI - GPT
- Boot from the image software rescue drive and delete the C: partition just created with the clean install and replace with the C: (Windows 10) partition from drive 1
You will end with EFI, MSR and Recovery partition from the clean install and the C: (Windows) partition from the current drive.
