I have an iMac, its OS (EL Capitan) is located on an external hard drive. I want to install WIndows 10 as a second OS on this drive.
But, since it is an external drive, I can't devide it into several partitions, using BootCamp Assistant.
Is there any way I can do it? Maybe I should use different software? Even solution, that includes erasing of the data is acceptable at the moment!
Thank you in advance!
