I cant even get to the installer screen yet.
From the information you have provided so far (I'll assume you have 1366x768 display), try this:
- create Unibeast USB from scratch
- boot with flags:
IGPlatformID=01660003 -v dart=0 cpus=1
Give the installer adequate time to appear. It is not quick (on my Lenovo u430 with i7, it takes more than a minute).
After you get through the installer (assuming the above flags work with default Unibeast USB), then you can move on to the other tasks.
Multibeast is not used until after installation. When you mentioned Multibeast, I assumed you had already completed installation. You should be familiar with the overall process:

Also, your profile is not filled out. I'm pretty sure I've requested this once already, but here is another...
Please provide complete details
in your profile.
System: manufacturer/model
CPU: detailed CPU model + motherboard chipset
Graphics: all graphics devices + laptop internal screen resolution
For example, typical Ivy laptop:
System: ProBook 4540s
CPU: i5-3320m/HM76
Graphics: HD4000, 1366x768
Use CPU-Z on Windows to find CPU (Core iX-xxx) and motherboard chipset (HMxx). For a laptop, these details are important and affect critical installation procedures.
