If you have an Optimus graphics model you are welcome to follow the link in my signature and use the files for XPS17 machine.
Does your guide also work for the L502x? L702x is almost the same as the L702x right? (I have the optimus with FHD and i7-2630qm)
I have one question:
I do have the UEFI enabled bios, but I would like to turn this option off again because of the problems in Windows. Is it still possible to install OS X then? I want to boot both OS (Windows and OS X) from the main SSD (250GB)
Because you mention this:
In case you want to boot Legacy Windows from primary HDD (because let's face it, Dell made it pretty hard to use UEFI Windows with all the freezing issues caused by their proprietary software while having a UEFI installation) and you have a caddy in place of your DVD drive with a disk you want to dedicate to booting OSX simply put you can't do that by default BIOS means as caddy is not bootable. You can only make it bootable as a UEFI medium and there is why this guide was even put together. Also I should mention that booting Legacy Windows from UEFI Clover is a big no go with Tiano firmware, so don't expect that. The only way to access Legacy Windows is to either use F12 and choosing Hard Disk or exiting Clover.
So does this mean I can boot legacy with both OS on the same primary SSD drive? What steps should I edit then?
And post installation you show this screenshot:
Do we L502x users need to take the 17inch option?
And the same here:
N.B. Make sure to rename EFI/config-17 or config-14 (depending on the computer model) to just config.plist, EFI/ACPI/patched-17 and patched-14 to just patched respectively!
Aslo doesn't it need to be EFI/CLOVER/config-17/14 instead of EFI/config-17/14 and the same for EFI/CLOVER/ACPI/patched-17/14 instead of EFI/ACPI/patched-17/14
