[GUIDE] Dual Booting on KitKat ROM's [Easiest] [NOOB Friendly] topic

Welcome to the NOOB Friendly GUIDE to DUAL BOOT 2 KitKat Roms on Samsung Galaxy S2!!
I know there already many guides on how to dual boot, but I found them confusing and wanted to clean out the process

Prerequisites :
1) Need Atleast 2.5 GB free on Internal Storage
2) Download the 1st Rom (Primary Rom) and save it on any storage on your phone
3) Download Latest Dorimanx Test Kernel v10.43.xx from Here - http://www.dorimanx.com/beta-test/
4) Download the 2nd Rom (Secondary Rom) on your computer.

Modifiying 2nd ROM :
1) Make sure you have WinRar installed on your PC
2) Download Patch for you 2nd ROM from here Dev-Host Link
3) Delete META-INF folder from Original 2nd ROM Zip (without extracting)
4) Copy META-INF folder from the patch you downloaded to the 2nd ROM Zip by using drag and drop (without extracting)
5) Now your 2nd ROM is Modified and Ready to be flashed as Secondary ROM

Steps :
1)Make sure you are on a KitKat Compatible Recovery
2) Flash any KitKat ROM (along with GAPPS etc.) you want as your Primary ROM
3) Reboot and check weather the ROM is working fine.
4) Reboot to Recovery
5) Flash Dorimanx v10.43.xx Kernel you downloaded earlier
6) Go to advanced in CWM recovery and Reboot Recovery
7) Go to dual boot options in new CWM and select Wipe 2nd ROM data/cache (takes 5-10 minutes)
8) Then select Wipe 2nd ROM dalvik-cache
9) After that Install 2nd ROM from Internal SD card or External SD card and flash the modified version of the 2nd ROM.
10) Reboot System and Enjow :laugh:
