Convert Windows 10 from Legacy BIOS to UEFI without Data Loss  

Using MiniTool Partition Wizard Free, you would want to delete the System Reserved partition. Then Copy the EFI System Partition to the empty space. Then Delete the old EFI System Partition. Would have have EFI System Partition - unallocated space - C: drive - unallocated space. Then you could MiniTool Partition Wizard Free to expand both ends of C: drive to fill the remaining space on the disk.

Hi,
If it's as easy as copy and paste why can't free minitool do it, I have my doubts in this process
I get the rest done it many times.

I found out that the copy partition in MiniTool Partition Wizard is only supported in the paid version. You could delete the old System Reserved Partition, manually create a new EFI system partition in the unallocated space, then delete the old EFI System Partition and resize your C: partition to fill the empty spaces.

Hi,
Yep
I'm all eye's and on the edge of my seat on how to manually adding the efi in front of C
Disk is the same as last posted last

Free reflect won't do what was said last
Sure it will image anything but it will not allow special placement and leave other partitions alone.

if I can get the efi to the old system reserved it's fine to
I wouldn't care if it's 708mb

format the 708mb to fat32 and set the id.

Then bcdboot or copy the efi folder from the previous esp partition to the new one.

I am lazy so I would do the above with the nice easy diskgenius.
