    open /Volumes/OS X Install ESD/BaseSystem.dmg
4. Restore “OS X Base System” to your USB Flash Drive using disk utility
5. Navigate to /System/Installation your USB drive Delete the “Packages” link
   then copy the “Packages” folder from “OS X Install ESD” to this location.
6. Open the Terminal, and enter the following:        
Quotes
cp “/Volumes/OS X Install ESD/BaseSystem.dmg” /Volumes/USB/ 
cp “/Volumes/OS X Install ESD/BaseSystem.chunklist” /Volumes/USB/
and install CLOVER boot loader on USB flash drive (Clover_v2k_r2747)
7.Now Copy the necessary kext which are needed for booting onto the drive.
Make a folder name 10.10 in USB/EFI/CLOVER/Kext/10.10/ and add those kexts on it 

FakeSMC.Kext
NullCpuPowerManagement.Kext 
AppleAHCIPort.kext
GenericUSBXHCI.kext
AppleACPIPS2Nub.kext
ApplePS2Controller.kext

8.Now install Clover Boot Loader on USB
9.Boot with USB and go into “Clover options”. & Change the boot-arguments to 
“-v kext-dev-mode=1” if you have HP laptop then change it like me else you will get 
Kernel Panic with LocalACPI
“-v kext-dev-mode=1 Cpus=1”
10.Install the OS X 10.10 Yosemite but do not restart when installation is done or restart
 and boot with USB again with same argument  
11. Open the Terminal and run the following: 
diskutil listTerminal
and identify your installed partition identifier like mine disk1s5 like mine and do the following
mkdir /Volumes/HD
mount -t hfs /dev//Volumes/HD
and copy your third-party kexts using CP as shown 
For example if I wanted to copy FakeSMC.kext:
cp/System/Library/Extensions/FakeSMC.kext/ /Volumes/HD/System/Library/FakeSMC.kext
Close Terminal and reboot into the OS X 10.10 partition,using the same boot-args as before
 
12.At this point, the system should boot. You may now install anything else you need (kexts, drivers) and begin using the system.
 13.Now once you got the Desktop install Clover Boot Loader on OS X 10.10 partition and Edit Config.plist with the help of Clover Configurator and add kext-dev-mode=1 and uncheck the No Cache on like this because Yosemite won’t boot without Cache 
Clover Config
Clover Config
14.Now save the file and Enjoy the new update of Apple 
Note:-Make sure use correct identifier while coping kext from terminal and make sure to add Boot-argument else your Hackintosh never gonna boot and this guide is tested on OS X Yosemite DP1-DP4
