i tried to install hackintosh on my dcommand r boot to recovery os dell vostro 2520. i followed all the steps one by one but i couldn't fine any option to change "ide to sata in BIOS ".(my BIOS only have few option not like other BIOS,i don't know why) but there is an default option call " sata config : archi mod " so i skipped BIOS option and started installing using my bootable USB pen drive. in the installation process i tried to change the NTFS formate drive to mac drive to install the OS but the system didn't allow me to do that its says " Couldn't modify partition map". i tried all the formates and partition but still can fix it.
NOTE: im running windows 10 C: drive and D: drive. so i shrink the drive for mac os. i cant delete and create the new partition in mac installation process because i need my windows C: drive and D: drive.
please help me to overcome from this problem. thank you.
