This happens when there is no AptioFix driver in /efi/drivers64UEFI folder, or when "slide=0" is not present in boot args when booting ML. So:
- double check your /efi/drivers64UEFI folder (not /efi/drivers64 folder) to have: FSInject-64.efi, HFSPlusX64.efi, OsxFatBinaryDrv-64.efi and OsxAptioFixDrv-64.efi, and nothing more.
- check if you have more then one config.plist in /efi/ folder and/or /efi/oem/.../folder - maybe you added slide=0 to the wrong one?
Thank you so much, dmazar! It was precisely this kind of info i was in need: concise, step by step troubleshooting. I'll try it in a couple of hours and report back.
No need to move kernel anywhere.
And you can leave boot1, boot ... files on the stick - the same stick can be used for BIOS CloverEFI boot and UEFI boot. You can test both ways from USB stick. No need to install/copy it to EFI partition until it works fine.
Did you already install it to EFI partition? Are you maybe changing config.plist and drivers64UEFI on the stick but booting from HD? Or vice versa?
I don't have an USB stick with Clover anymore, so i'm trying this with my main OSX partition. I already have Clover running in a smooth setup, albeit from BIOS. I want to try UEFI first because my board is UEFI, so why not use it?, second because i want to avoid resort to DSDT edits, since i'm so bad with it, third (but related to the second) because i want to try to use both my integrated and my discrete graphics card at the same time and, since i know it's possible with DSDT edits, perhaps i'll nail that using UEFI.
That's the one i already have. But thank you anyway.
EDIT: It worked! I don't understand why, since i own a Gigabyte UEFI board (the H77-DS3H), i needed to add these two other drivers (specially the Aptio one), but what really matters is it worked! Now i have both EFI and BIOS boot with clover. Thank you very much, dmazar!
I added also the CRMVideo driver, to get proper boot screen resolution, along the correct keys/strings under "Graphics" in the config.plist (i had already added my EDID from darwin dumper since i was using BIOS boot, much like with my netbook). Still no luck: the boot screen is inside a black frame circa two inches tick. I hope i have better luck with my system now, since its chipset is Intel.

UEFI boot didn't get both my cards (HD4000 and 9800GT) to work together, as i was expecting. On the contrary, when i enabled my internal graphics and set it as primary, Clover simply refused to boot from UEFI. Strange. But on the other hand, my system is booting in less than 20 seconds. Not bad for a system that relies on an old 2'5'' HDD scavenged from a broken EeePC 1005H.
