Hi there, i just installed OS X Yosemite with my usb stick. My pc: asrock h81m-vg4, Asus gt640, corsair 8gb ddr3, i5 4460, ssd Kingstone 240gb. I can only boot into Yosemite by using USB stick. I installed clover selecting the options :"Install for uefi only", "install in the esp", and i selected emuvariable, partitiondxe and optiofx...and target script. Then i converted the EFI partiton from HFS to FAT32 as indicated in the guide. But when i restart computer bootloader wont appear, but if i get in the pen drive it boots up...what s the problem???? Thanks !!!

Did you copy your EFI folder from your usb to your FAT32? Usually if you install clover it will overwrite your config in your EFI on a fresh target and then obviously your setting in the config list all wrong and so are your kext's.

Hey there, thanks for reply...i tried to copy the entire folder EFI of the USB to the EFI folder of the SSD...but i still cannot boot...it seems the pc cannot see the EFI partition at startup..how is it possible? maybe it should not be FAT32? i don't know ...please help me :(

Your EFI partition might be corrupted.  Did you convert to HFS and install Chameleon there previously?

What is the output of "diskutil list" when run in OSX terminal?
eg

diskutil list
/dev/disk0
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *500.1 GB   disk0
   1:                        EFI EFI                     209.7 MB   disk0s1
   2:                  Apple_HFS Mavericks               124.4 GB   disk0s2
   3:                 Apple_Boot Recovery HD             650.0 MB   disk0s3
   4:         Microsoft Reserved                         134.2 MB   disk0s4
   5:       Microsoft Basic Data SHARED DATA             249.8 GB   disk0s5
   6:       Microsoft Basic Data WIN7_X64                125.0 GB   disk0s6

Note "TYPE" and "NAME" should both be "EFI" for partition 1.

 

You can try reformatting the EFI:  In terminal, type the following commands, followed by <Enter>...
 

diskutil unmount /dev/diskXs1 (where X=disk number of your hard disk)
sudo newfs_msdos -v EFI -F 32 /dev/rdiskXs1

If the partition type has been changed from "EFI" to something else, you can repair it using the "GDisk" utility - see part III of post#359.

Hey there! Thanks for reply. So

 

1) i never installed chameleon. This is the first install on my new ssd and i installed clover as UEFI.

 

2) this is the output of the photo:

3) could it be a config.plist problem? I tried to change some options (some fix in ahci with clover configurator) and now i am able to boot up!! How can i see if my config.plist is correct for my configuration?

 

Thanks a lot!!!
