Ok. Try to explain in detail what issue you are having? What version of clover is installed on your USB drive?

i would use UEFI for install.

Need to know what boot flags you're using and take a screen shot to where your install process is failing at.

Make sure you're using a usb 2.0 port.
 
boot safe mode

thanks for replay


i use now UEFI

I tested it with

dart=0 nv_disable=1 -x -f----- same error
dart=0 nv_disable=1 ------ same error
boot mac os x in safe mode------ same error

i use usb 2.0

i use UniBeast 6.0.1
 
Try the npci=0x2000 bootflag. I always have to use that.

Also confirm that you optimized your bios (F5) and disabled your vt-D and CFGlock
 
Which version of clover are you using?

you might want to try and download the latest clover v_3300+ and install onto your USB drive.


Make sure nothing else is plugged into your computer. (Are you using onboard graphics?)
 
should i install the system first and then install clover ?? i dont install any clover yet ,

i just flow the guide
 
and if you are still having trouble, follow this guide very closely to see if you can get it fixed.

if you can get yosemite to work on your set up, then you are very close and may just need to tweak a few things to get el capitan working (i know the usb drivers are different for el capitan)... but you aren't at the post installation tools yet, are you?
