I have problems with Windows booting

Hello everyone, I have a problem. I have installed on a disk windows 11 and on another disk windows 10. The problem is that the boot manager is only present on the disk where windows 11 is. When I try to boot from the windows 10 disk it does not boot. Is there any solution to this? Because I want to remove the disk with windows 11 and I can not for this reason. Thank you very much in advance. Best regards
