put in USB/Extra/Extensions and use this boot flag: -f -v GraphicsEnabler=No npci=ox2000






6. Go back (ESC), go to Power Management

7. Set the ACPI Suspend Type to S3(STR)

8. Set HPET Mode to 64-bit mode

9. Save and Exit, by pressing F10

ok, this because your partition is not active, try active partitition with commands from Terminal app, open Terminal app an put sudo -s



put this i386 folder in the desktop



Look for your boot partition's identifier (diskXsY):



diskutil list : EX: disk0s2 in this example is disk0s2 see for your disk


Get root access:

sudo su


cd /Users/your user/Desktop/i386


Install boot0 to the MBR:


./fdisk440 -f boot0 -u -y /dev/rdisk0


Install boot1h to the bootsector of the boot partition:


dd if=boot1h of=/dev/rdisk0s2


Copy the file "boot" to the partition:


cp boot /


Set the partition active:


./fdisk440 -e /dev/rdisk0


p <-----> (print a list on screen)

f 2 <-----> (makes partition 2 active) see your Partition

w <-----> (write to disk)

y <-----> (yes)

cd /Users/your user/Desktop/i386


cp boot /





cp -R boot /



or copy and paste, see it is only one space in the command for copy : cp space boot space /



Set the partition active:


./fdisk440 -e /dev/rdisk0 enter

p enter <-----> (print a list on screen)

f 2 enter <-----> (makes partition 2 active)

w enter <-----> (write to disk)

y enter <-----> (yes)
