Also, you mentioned that your u410 is identified as a MB Air and the 6.0 version of multi beast does not have MB Air as an option. Any help is greatly appreciated.
When you open multibeast, go to the first tab and select "DSDT Free"
------
proceed to the next tab "Drivers"Click on "Disk"
Deselect 3rd Party SATA
Select 10.9.0 Trim Patch
Click on "Network"
Select Realtek - AppleRTL8169Ethernet 2.0.6
Click on "System"
Patched AppleIntelCPUPowerManagement, select OS X 10.9.0
------
proceed to the "Customize"tabClick on "Boot Options"
Deselect Hibernate Mode = Desktop
Select Hibernate Mode = Laptop
Click on "System Definitions"
Select MacBook Pro 8,1
------
proceed to the "Build" tab, Verify:
Quick Start > DSDT Free
Drivers > Disk > TRIM Enabler > 10.9.0 TRIM Patch
Drivers > Misc > FakeSMC v5.3.820
Drivers > Network > Realtek - AppleRTL8169Ethernet 2.0.6
Drivers > System > Patched AppleIntelCPUPowerManagement > OS X 10.9.0
Drivers > System > AppleRTC Patch for CMOS Reset
Bootloaders > Chimera v2.2.1

Customize > Boot Options > Generate CPU States
Customize > Boot Options > Hibernate Mode - Laptop

Then Run/Install
With this you will be able to boot without having already made a DSDT and/or SSDT.
Use the same boot flags that you used to boot the installer:
GraphicsEnabler=No IGPEnabler=Yes IGPlatformID=01660003

After you get that done you can generate one for MBA5,2 easily using Chameleon Wizard (link provided in main post).
