Partition Help Needed

With minitool partition wizard you can enlarge recovery partition as it is in current location.

Install minitool partition wizard. Launch and right click on the recovery partition, choose extend, next to take free space from: in the drop-down menu choose the c: partition (if there was unallocated space you will have the choice to choose the unallocated space too, but this is not required) , drag the slider right or left to choose the quantity, click OK, and at the top left click apply.

You can reduce the first partition to a size of 100MB to redo the efi partition, and 16MB for the msr partition. The space that will remain you recover it with minitool partition wizard in the same way as to extend the recovery partition indicated above.

You do everything with minitool partition wizard. You can gobble up unallocated space or partitions regardless of their location.

Playing with partitions is a risky task. Make a backup before you begin

This is what I would do:

- Delete the old System partition, create a new EFI and MSR partitions and load the boot manager to it.
Open a CMD window as administrator and type:

diskpart
list disk (it will list all drives. Identify the main drive number)
select disk n (replace n by the main drive number obtained with list disk)
select part 1
del part override
create part EFI size=100
format fs=FAT32 quick
assign letter=W
create part MSR size=16
exit (to exit diskpart)

bcdboot C:\Windows /s W: /f UEFI

diskpart
select vol W
remove letter=W
exit

- Delete the current EFI partition and create an unallocated space

Diskpart
list disk (it will list all drives. Identify the main drive number)
select disk n (replace n by the main drive number obtained with list disk)
list par <- note which partition is the old EFI System partition
select part # <- replace # with the partition number identified above
del part override
select vol C:
shrink desired=350
exit

Now you should have:
- 100M EFI Fat32 - partition
- 16M MSR RAW - partition
- 484 M unallocated space
- 1861G C: NTFS - partition
- 450M unallocated space
- 557M Recovery NTFS - partition

Reboot to see if everything is working as it should

- Join the unallocated space to the recovery partition

Open a CMD window as administrator and type:
reagentc /disable (Important)

Now use Minitool to expand the recovery partition to the left, taking all the unallocated space.
Use Minitool to expand the C: partition to the left, taking all the unallocated space

You will end with
- 100M EFI Fat32 - partition
- 16M MSR RAW - partition
- 1861G C: NTFS - partition
- 1007M Recovery NTFS - partition

Finally
Open a CMD window as administrator and type:
reagentc /enable
