When i go to the screen of the install There is no HDD(Yosemite drive) to select as an install location, and also there is no HDD in Tools> Disk Utility too. it show only USB in Disk Utility and in install location section.
I had this problem in the past when i went install maverik and yosemite, but with inject KextBeast.Pkg into these OS my HDD showed, unfortunately this PKG dosen't work on EL Captain. so is there any similar PKG for EL Captain like KextBeast.Pkg?
