corrupted winload.efi in a windows 10 copy

I have got a mini computer with 32Gb of internal storage. Windows 10 takes at least 20Gb and the disk is now full.

So I decided to move the system to an external HDD SSD drive, using minitool partition wizard.

After the cloning, I have got this configuration:

disk 1 is the internal disk. You can see 2 EFI partitions in the 2 disks(I don't know if it is important but maybe there should be only one).

When I try to start my computer, I am asked to choose which windows to launch. If I choose the first, the OS starts fine(but I have no more enough space). If I choose the second, I have a blue screen and a message :

error 0xc000000e one required file is missing of contains errors. \Windows\system32\winload.efi

thanks to google, I learnt the it means an important boot failure, and saw some ways of fixing that; one way is :

• enter in the terminal via a windows distribution disk
• bootrec /ScanOs
• bootrec /RebuildBcd
• bootrec /FixMbr
• bootrec /FixBoot

but then I have an arror after "bootrec /RebuildBcd" : if lists one disk, I get a question ("add installation to boot list?"), and then I get the error "the system cannot find the file specified".

My questions are:

• maybe a good tool to copy/move a windows 10 system could avoid me too long fixes
• if not, is the problem linked to two EFI? if so, can I remove one?
