Help me have the recovery partition install my windows 11 again

[agalvis]

hello, I recently bought this EliteDesk mini computer. It has an M2 disk. The first time I turned it on, it went directly into win11 install and installed correclty. Then, I wanted to add a second HDD with a win1o installation. It gave me a lot of trouble but finally using EasyBcd it managed to work, but it never booted back into win 11. After long hours I decided to download a pirated win11 partition that finally let me in but I want to recover the real authentic one that came pre-installed in this equipment. I know I must have messed up everytying when I decided to use EasyBCD, but after booting into the pirated (2nd HDD) I can see my M2 disk has the following partitions:

FAT 16 (100 MB)

Other (16MB)

NTFS (476.23GB)

NTF S (604MB)

It used to be disk 0 now it became disk 1. The second HDD that I brought it now became disk 0 and is running some torrent win11 on it that I don't like

The million dollar question: how can I have my elite desk boot into that beautiful recovery partition, reinstall windows11 (authentic) and be happy and move on with my life? 

Also, I have tried to use boot recovery and nothing works. It actually shows me a win10 boot screen not win 11

Is that FAT 16 a problem Easy BCD created? 

I want to recover my authentic windows partition and have dual boot systems. 

Your help highly appreciated

hi

Why try a pirated version!
you can use microsoft tool without problem normally
As for the installation in multi boot it would be necessary to check
but I had made the same error with windows 7 at the time, finally I did not want to reinstall everything
easy bcd had been very helpful
but I had read that you had to do the installation in a specific order at the time windows xp and after windows 7
maybe it's still the case

The pirated helps me bypass the TPM 2.0. This one has TPM 1.X. How can I recover that previous partition without reinstalling everything? is the FAT partiti9on in the VME even normal?
