Hoping someone can give me some help to fix my (or my partition software's) mistake. The quick version is, on a mac 5,1, I have an ssd with 4 partitions; 1) my opencore efi, 2) windows, 3) Monterey, and 4) photo storage for mac os. What happened was my Monterey partition was too small, and the only place I was able to format was the windows. I used easeus to allocate space on the windows partition and in doing so it messed up the Monterey and photos partitions. I have full backups of the photos, but not of Monterey. The issue is the Monterey part had all my opencore things on it. I do have a fully functional Catalina drive that is separate on an nvme, and my opencore efi seems to be functioning. I have a bootpicker on startup, and can pick between windows and Catalina. So the question is, can I just format the partitions that are damaged/unreadable (all data is there, file system isn't working), go into Catalina and use opencore to install Monterey fresh, or will that mess anything up as far as the boot efi? I'm pretty new to all this opencore stuff so not really sure how that would work. Thanks for any help you can offer
