Hi,
I have accuretly followed the probook installer guide but still no display output witch is mandatory for me.
If somebody had the same problem, I would appreciate any advice !
Thanks for your kind help.

Many Thanks ! But that means that I have to re-install my dual boot full system ? Damned ! :crazy:
I am not a fan of the new apple OS so I would like to know witch is the faster : Yosemite or El capitan ?
No way with ML ? :oops:
Cheers...

The guide supports all versions of OS X (for your system, 10.7.5->10.11.5).
There is a section on transition from PBI-CE based install.

Please read the guide. Carefully.

Hi,
Thanks for this wonderfull guide that should work for me but I spent my week end on trying to install ML with no success.
I did something wrong... I Don't know what...
I created a usb key with Clover and mac OS install partition.
I booted on this USB on my target Probook (4740s)
Created 2 partitions on my SSD using disk utility just before OSX installation- 1 Fat32 (1 go) - 1 Mac os extended +J
Installed ML on the Mac os Ext+J
Installed clover (Clover_v2.3k_r3577 - witch I previously copied to the usb) on the fat32 partition

But the result is that I face a kernel panic with "CPU power management" each time I try to boot from the SSD. I changed the drop table in the "config.plist" - redone the entire install starting from scratch, but still have this kernel panic.

Any kind advice would be A LOT appreciated.

Thanks for your help.

Something strange I did not mentionned is that after ML installation the installer ask to reboot and it works !!! I have the ML desktop. At this step I install clover to the fat 32 partition and when I try to reeboot from the SSD I see the clover screen then boot from the SSD and get the kernel panic.

Any idea ?

Many thanks.

Last thing : after ML installation as long as I let the usb pluged in, I can boot from the SSD and having ML desktop. If I unplug the usb -> kernel panic.

May be a new idea ? :rolleyes:

Thanks.

Boot verbose, show photo. Attach EFI/Clover folder as ZIP (omit 'themes' folder).
 
Many thanks for your kind help !

After more hours spent on that issue i can only boot to ML desktop if Start ->F9 -> boot from EFI file -> Clover_EFI (on usb) -> EFI -> CLOVER -> CLOVERX64.efi -> then Clover startup screen (where I can choose OSX install (on usb) or ML on SSD so I choose ML on SSD -> ML desktop.
If I try to boot directly from the SSD then bios alert : no boot device.
If Start ->F9 -> boot from USB key -> then no boot device -> esc -> esc -> clover startup screen -> ML on SSD - Kernel Panic
I run Clover_v2.3k_r3577 from the ML desktop but it did not create any EFI folder in the FAT 32 partiton ! As you can see in the zip file : https://www.dropbox.com/s/upnyi48icv4si3u/WDM EFI files and screens.zip?dl=0

I am sure that clover is the best solution comparing to chameleon I would really like to use it correctly on my probook.

Again, thanks for help.

Kind regards.

It means you didn't install Clover to your SSD.

Make sure you follow the guide linked by post #2 carefully.
