I have macbook air 2015 on Catalina Version 10.15.2 . So previously I had ran into this issue MacBook filesystem FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF after deleting linux partition and thank god I fixed it but I was not able after that to boot into windows 10 it was entering in recovery screen with error code 0xc00000e. So I deleted bootcamp and tried to reinstall it. I download latest windows 10 64 bit iso file and when I tried to install it via bootcamp it says Disk Could Not Be Partitioned! I tried running first aid from disk utility but it says that there are no problems. I just don't know what to do any help would be appreciated!
