Disk 1 Partition Issues

VE3YF said:

So if I can create a System Partition on Drive 0, does that mean the Boot Manager can be moved to the new System Partition on Drive 0

If drive 0 is GPT you can just create a EFI partition and load the boot manager on it.

diskpart
select disk 0
select vol c
shrink desired=100
create part EFI
format quick FS=fat32 label=EFI
assign letter=W
exit
bcdboot C:\Windows /s W: /f UEFI
diskpart
select vol W
remove letter=W
exit

Reboot, enter BIOS and set to boot as UEFI - GPT
Set boot priority to Windows boot manager on drive 0

The instructions on the post above are easy and simple.
The down side:
- The EFI partition isn't the first
- There is no MSR partition
- There is a EFI partition between C and the recovery partition.
- The recovery partition is small (should be at least 850M)

If you want to make it right I can give you the instructions

Ok all went well. Many thanks.

I do notice that the system partition on disk 1 has no been given a drive letter of H

Can I delete that partition as it is now empty

Yes, and I just noticed that the recovery partition on Disk 0 is now called a basic data partition and it is now at 546mb. I think the recovery partition should be around 700mb.

Partition letters are assigned by the OS. If drive 1 has no Windows on any partition you can delete the partition.

The recovery partition should be at least 850M
KB5034441: Windows Recovery Environment update for Windows 10

Open a CMD window as administrator and type:
reagentc /info

MS instructions to enlarge the recovery partition won't work as you have now a EFI partition between C: and the recovery partition.

- You can use some space from drive D: to enlarge the recovery partition
- You can make some space on the left of the C: partition, create a new EFI and MSR partition, delete the actual EFI partition and shrink the C: partition in 350M and finally expand the Recovery partition to the left.

You will need a good partition manager as Minitool to do option 1 or 2

Everything has been corrected.

EFI Boot Partition is now on Disk 0 and the recovery partition has been reinstalled at 800mb. Thanks to everyone that has helped out.

Sure saved a lot of grief of doing a re-install of Windows. Thanks again.

You must have a reason not to show the result

Yes actually I had a couple of appointments I had to go to. Here is the result from Computer Management.

But now leaves only one question, is it safe to get rid of the 546mb (Healthy Basic Data Partition - Partition 4) and join it with the Healthy Basic Data Partition on its right)
