I cleaned my Mac disk while dual-booting Mac and Windows

I was trying to dual-boot Mac and My Windows and as I was using Mac mini 2012 it was showing an error Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disks So I was watching a fix on YouTube which asked to use diskpart and clean the drive then I realised my Mac os was cleaned. So I just continued to install windows and made a disk partition and left space for the macos

Could someone help me figure out on how to install Mac os back
