Dual Booting Ubuntu, Kernel Panic - not syncing: Attempted to kill init! exitcode=0x00000009

I followed the tutorial from the ubuntu website. checked the md5. installed the iso into a usb drive using rufus. i tried a different usb. It still doesn't work. This is the first time im trying to install ubuntu alongside Windows. I tried booting the iso file with a Virtual Machine and it works perfectly fine. It installs and everything. Please help!
