crwdns2934249:0crwdne2934249:0:
I have upgraded an second hand Imac that had a 1TB hard drive with an I7 upgrade and Replace the 1TB mechanical HD with a 1TB SSD and also installed a 1TB NVMe drive with and apple adaptor. I have been able to install a fresh copy Catalina on it and have been trying to install windows 10 on it also. I keep having errors with bootcamp. When I try to create the windows 10 install disk it give me an error formatting drive. I have searched for help on the internet but what am I doing wrong? Any help would be great.
Thanks
Mike
