[Solved] E7440 won't boot from OC USB
LyonLeBrun posted a topic in The ArchiveMy Latitude e7440 won't boot from an OpenCore installer USB stick. Here's what I've done: 1. I created the USB stick by formatting the entire USB device in macOS (Catalina) to be GUID Partition Map and Mac OS Extended (Journaled) file system. I used createinstallmedia to copy Catalina onto the USB drive. I also copied Jake Lo's OC 0.6.0 folder from the post below into the EFI partition (I used MountEFI to make the EFI partition visible in the Finder). 2. I plugged the USB drive into my Latitude E7440, and got to Boot Options. I set the USB drive to be first in the list, and used Hervé's list to configure the rest of my E7440 BIOS Settings. 3. Each time I boot, the USB drive is skipped/ignored, and the laptop boots from the internal drive. What should I investigate to make the computer boot OpenCore from the USB drive? PS I don't think it would matter, but I should note that the laptop has a previous macOS install based on Clover. Once I get OpenCore booting, my plan is to erase the entire internal drive and do a clean install of macOS Catalina ... Thanks!
