Make sure your BIOS is completely up-to-date, get it off the Lenovo website, and set your BIOS settings to boot UEFI first. You can install the Clover with UEFI or old-style DOS bootloader, or even both when you run the Clover Installer which is a download here.
How do I do this with opencore? getting the same error when trying to boot without USB.
 
I've just installed Catalina on my Lenovo E73.

Because the USB installer was configured for UEFI boot, I had to reinstall Clover Legacy Boot Mode v2.5k r5102 to the hard disk afterward.

It now boots from the local disk in Legacy mode, without requiring the USB drive :thumbup:

 
Hi, I also have this problem Dell error 1962 with my lenovo s500, I updated the BIOS but same error, I set the BIOS as described above but no same error, I changed the Clover to Clover lagacy, but nothing starts with USB only inserted, who can help me to start Mac OS with SSD?
THANK YOU
