I had the same message at some point in my search to boot linux. I wanted to boot linux without using grub, directly with OpenCore. After trials and error I succeeded with OpenCore 0.7.4, with drivers ext4_x64.efi and OpenLinuxBoot.efi, with the following settings in config.plist:Boot MacOS OK
Boot Windows OK
Boot Ubuntu OK but...
if:
- I remove BlessOverRide item0 "\EFI\ubuntu/grubx64.efi",
- OpenLinuxBoot.efi is ON
then: when I choose the Linux drive on OpenCore GUI, it starts but it fails with the following message displayed on the screen
Misc: Security: ScanPolicy=16129
UEFIDrivers: Ext4_x64.efi: Enabled= true
UEFIDrivers: OpenLinuxBoot.efi. Enabled= true + Arguments= flags=0x0000018F
The flags for OpenLinuxBott.efi refer to:
- 0x00000001 (bit 0) — LINUX_BOOT_SCAN_ESP, Allows scanning for entries on EFI System Partition.
- 0x00000002 (bit 1) — LINUX_BOOT_SCAN_XBOOTLDR, Allows scanning for entries on Extended Boot Loader Partition.
- 0x00000004 (bit 2) — LINUX_BOOT_SCAN_LINUX_ROOT, Allows scanning for entries on Linux Root filesystems.
- 0x00000008 (bit 3) — LINUX_BOOT_SCAN_LINUX_DATA, Allows scanning for entries on Linux Data filesystems.
- 0x00000080 (bit 7) — LINUX_BOOT_SCAN_OTHER, Allows scanning for entries on file systems not matched by any of the above
- 0x00000100 (bit 8) — LINUX_BOOT_ALLOW_AUTODETECT, If set allows autodetecting and linking vmlinuz* and init* ramdisk files when loader/entries files are not found.
With those settings (no BlessOverride, no Entries) Linux (Ubuntu in my case) doesn't use grub, boots super fast, without problems.
