osx slow when boot from hdd, works ok from usb

[snikrs]

Hello,
I did clean install and post installation with multibeast (legacy boot, sound and network driver, ssdt sandy bridge i7, iMac12.2 definition). It works fine if I start OSX from usb installer (created with unibeast), but if I start OSX from HDD everything becomes slow and unresponsive, freezing for few seconds all the time (rotating bar). Did I miss something?

Copy the EFI folder of your usb installer drive to the desktop, now mount the EFI partition of your hard drive, find and delete the EFI folder that is currently on the hard drive and replace it with the one you copied from the usb drive.
