Had a really productive night last night, managed to create the right USB setup to install Sierra.
After about 1 hour, the Latitude finally booted showed Sierra running in all it's glory.
Remembering from when i got Yosemite running earlier this week, I needed to mount the EFI of both the USB drive and the internal hard drive.
So i copied the clover directory from the USB over to the EFI on the hard drive....and rebooted
I then get invalid partition again.......nevermind i thought......inserted the USB and requested a boot from that again.
The only boot options (even after pressing F4) is boot from recovery or reinstall.
Thinking that I've done something wrong, re-installed for the 2nd time......alll installed fine, did updated etc.
Did the same again as per the instructions here :.. https://osxlatitude.com/index.php?/topic/7539-yosemite-installation-guide-latitude-e5440-intel-i5-clover-uefi/
Same again.......so after a 3rd time re-installed, I thought I'd reboot the mac from the USB (without copying clover over) & there is no option to boot from the internal hard drive.
What am I missing (sorry for the long thread)
