Can't partition disk for Boot Camp When partitioning my disk to install Windows, it said an error occurred and that my disk couldn't be partitioned. But Disk Utility couldn't repair it. Can I do something to fix it without having to erase it completely?

Boot Camp error occurred while copying Windows files (novice help please) Hello, while I downloaded 64-bit Windows 10 from microsoft.com then tried to install via BootCamp and got the error about copying Windows files. It then got stuck rolling back the partitions created. I'm a complete novice at this, so I read other threads for help. I'm not skilled enough to even attempt the 9-step work arounds and things like that that I've seen. I found one thread that suggested this: diskutil eraseVolume fat32 BOOTCAMP disk0s4 and now run BC Assistant and try to Remove/Restore. I actually got that to work after a reboot. Yay me! However I'm still wanting to install Windows via BCA but I am not capable of complex coding and such. I've seen one suggestion of installing a later version of Windows and that has worked. Is anyone familiar with a simple fix like this work and would be able to walk me through? THANK YOU!

Boot camp - MacOs Mojave - "Your disk could not be partitioned" when patition size is above 40BG Hi, So i tried to install windows 10 in my macbook pro using boot camp and always got this error "Your disk could not be partitioned" no matter what i did unless the partition size for boot camp is 40GB. I have no idea what is the problem. Someone please help me, I'm an engineering student and I really need windows 10 in macbook with at least 90 GB of partition size. I have a Macbook pro 13" with touch bar 256GB late 2016 model. (FYI when i first bought my macbook(2017) with macos sierra at that time, i installed windows 10 using boot camp and it worked well, but later removed it.) my macbook is equipped with mojave up to date as of oct19, never used time machine and file vault. Attempt 1: I downloaded windows 10 May19 ISO and opened Boot camp, set 90GB as partition size. got this error. but when i set the partition size as 40gb it worked. Attempt 2: Formatted main internal disk and reinstalled macOs mojave. Still got the same error. Attempt 3: Formatted main internal disk, downgraded to High sierra and Still got the same error. Attempt 4: Upgraded to mojave and still have the same error.
