If you use separate disks there shouldn’t be any issues.
Out of morbid curiosity I just installed Windows 11 on a spare ssd alongside my main Fedora install. All I had to do was re-add the Fedora disk to first in the boot order and rebuild the grub config with os-prober enabled to add the windows install to grub
No issues apart from Windows 11 being horrible
noice! I just switched to using Fuzzel yesterday.
