Default [Q] Problem with installing MultiROM for TF300T

I have a problem with installing MultiROM for TF300t. There is another user, AgentTabasco, that has the same following problem

"I have been trying to follow the directions on this and get the multi-rom installed but I keep getting a fail. This is what it says when I try to install from the multi-rom TWRP:

Failed to create fake boot image filePrimary/boot.blob (No such file or directory)!
Restoring mounts...
Updating partition details...
Error flashing zip 'external_sdcard/
updating partition details...

and from here it shows Failed."

I also have the same problem. I just unlocked the bootloader, installed TWRP using terminal emulator, and tried to install MultiROM using TWRP on stock rom but get a failure.
