4.5 Manual execution of shim first-stage boot loader may fail in the UEFI shell

Manually loading of shim binaries from the UEFI shell may fail in some scenarios. The following cases are known to fail:

  • FS0:\EFI\redhat\shimaa64.efi

  • FS0:\EFI\redhat\> shimaa64.efi

FS0:\> \EFI\redhat\shimaa64.efi is known to work correctly.

A standard installation is unaffected by this bug. The problem is limited to the manual execution of shim in the UEFI shell.
